What Is a Population Parameter

In statistics, a population parameter is a number that describes something about an entire group or population. This should not be confused with parameters in other types of math, which refer to values that are held constant for a given mathematical function. Note also that a population parameter is not a statistic, which is data that refers to a sample, or subset, of a given population. With a well-designed study, you may be able to obtain a statistic that accurately estimates the true value of a population. Key Takeaways: Population Parameter In statistics, a population refers to all the members of a group of people or things. A population can be large or small depending on what you are interested in studying.A parameter is data that describes the entire population, while a statistic is data that describes a sample of that population.A sample is a part, or a subset, of a population.With a well-designed study, a sample statistic may provide an accurate estimate of a population parameter. What Is a Population? In statistics, a population refers to all the members of a group. A population can be large or small depending on what you are interested in studying. For example, a population could be â€Å"all the residents of Germany†Ã¢â‚¬â€which in 2017 was estimated to be about 83 million people—or â€Å"all the freshman in a certain high school†Ã¢â‚¬â€which can range from a single person to a couple thousand depending on the school. And though you may have heard the term â€Å"population† in reference to people, a population can refer to other groups of things as well. For example, you may be interested in studying the population of birds that live near a certain beachside area, or the balloons produced by a specific manufacturer. Population vs. Sample No matter how large or small a population may be, a sample refers to a subset, or part, of that population. For example, if the number of freshmen in a high school class is 100, you may choose to study only 45 of the students. Statistical studies typically use samples instead of populations because it may be costly, time-consuming, or simply impossible to find or reach out to everyone in a population. Nevertheless, if you are conducting a statistical study, you should try to design your study so that it accurately represents the population. For example, if you want a sample representing all the people residing in Germany, you may want to randomly select people from every part of the country. You should also make sure your sample size, or number of things you are studying, is large enough so that your data becomes statistically significant: it accurately estimates the true statistics regarding a population. What Is a Parameter? You may have already heard of parameters in math, which are values that are held constant for a given mathematical function. In statistics, the definition of parameter is different. A parameter is data that refers to something about an entire population. If your population is all the lunches that the students in X high school eat on a certain day, a population parameter might be that 35 percent of the lunches are brought from home. Parameter vs. Statistic Parameters and statistics are very similar in that they both say something about a group—for example, that â€Å"20% of MMs are the color red†Ã¢â‚¬â€but the key difference is who or what they are describing. Whereas parameters refer to an entire population, statistics refer to part of that population, or the sample of the population that was researched in a study. For example, in the above example, instead of going through all the MMs in existence and counting how many red ones there are to obtain a population parameter, you may count how many red MMs are in several packs to obtain your sample’s statistic.  If your study was designed well, the statistic you obtain should closely estimate the actual population parameter.

Estrangement in Joseph Conrads Amy Foster and in Rebecca...

Estrangement in Joseph Conrads Amy Foster and in Rebecca Wests The Return of the Soldier The concept of male estrangement in an alien environment is portrayed in both Joseph Conrad’s short story, Amy Foster, as well as in Rebecca West’s book, The Return of the Soldier. First, there are adverse reactions to the male protagonists’ placement in their environments. The reactions vary between the protagonists and the people they come into contact with. Second, there are similarities and differences between the way the two authors chose to explore the situations presented. Third, both protagonists handle their estrangement differently. It is hard to behave appropriately when you are among peculiar customs. It seems ironic that†¦show more content†¦This causes him to develop â€Å"A complete case of amnesia†¦His unconscious self is refusing to let him resume his relations with his normal life, and so we get this loss of memory† (West 79). In a sense, Chris becomes trapped in his past. Fifteen years earlier to be precise. Because of his amnesia, Chris responds to the reality of his â€Å"current life† with a sort of disbelief. For example, when his wife Kitty is mentioned, he replies: â€Å"I haven’t got a wife! Has some woman been turning up with a cock-and-bull story of being my wife? Because it’s the damnedest lie!† (West 20). Of course his wife has her own take on the entire matter, and one that is hardly full of sympathy and support. For example, West writes on page 31: â€Å"†¦her pink mouth went on manufacturing malice. â€Å"This is all a blind,† she said at the end of an unpardonable sentence. â€Å"He’ s pretending†¦Ã¢â‚¬ . Kitty refuses to accept the current situation, and views it with a sort of vindictiveness. In both situations, the protagonist is alienated, and in both situations, others treat the protagonist harshly. The people involved in the harsh behavior are not consistent in both stories. In Amy Foster, the people conducting themselves in a harsh manner are the average citizens with which Yanko Goorall has contact. For example, there is the milkman, who whipped at Yanko; Mrs. Finn, who berated Yanko with an umbrella; and Mrs. Smith who failed to ever trust Yanko.

Economy, Society and Politics in 19th Century London free essay sample

Indeed, studying the large-scale improvement scheme of London’s streets in the nineteenth century brings to light the radical change in sanitation levels, the presence of poverty and social disparity which was still rife and the advent of leisure and a growing middle class, visible in new public spaces which continue on from the street, such as parks and gardens. These ideas will form around the analysis of three pieces of visual art dating from nineteenth century London. Let us first look at Figure 1 of the crossing sweeper and the lady. In this painting by William Powell Frith is depicted a typical street scene of Victorian London. Indeed, crossing sweepers were very present, as expressed by Henry Mayhew in his extensive study of London, London Labour and the London Poor: â€Å"We can scarcely walk along a street of any extent, or pass through a square of the least pretensions to gentility, without meeting one or more of these private scavengers. † (Mayhew, 1861). These ‘scavengers’ constituted a large part of London’s poor; in the painting the young boy offering his services is barefooted, his trousers and vest ripped and his overall appearance one of ruggedness and misery. This is perfectly contrasted by the lady, who on the contrary is in luxurious attire; a velvet overall covering her and her leather boots shining. Behind her stand white and grandiose buildings with stucco facades which place the painting somewhere in West London. As explained by Bills (2004) the presence of a Notting Hill omnibus and the painter’s familiarity with Lancaster Gate suggests the painting could more precisely be inspired from the Notting Hill area. Beyond the very organisation of the painting however is its message. The lady, who is trying to cross the street whilst ignoring the young boy who asks for money, is walking by foot rather than travelling by carriage, which would have been expected by a woman of her stature at the beginning of the century. This change in behaviour was brought about by the major development scheme to clear the streets of London organized by the Metropolitan Board of Works. At the start of the century, sewage management was highly inefficient and, needless to say, extremely unhygienic. Before the research completed by pioneering physician John Snow, the miasmatic theory was largely held that disease was spread through the air rather than, as Mr Snow elucidated, through water, which he demonstrated to cause the spread of cholera. This new information, along with the Great Stink of 1858, compelled legislators to better manage London’s sewage works. The city moved from private enterprise of water supplies and sewage treatments to modern hydrological systems that worked as a whole. By 1855, the Metropolis Management Act was passed which created the Metropolitan Board of Works, an authority aimed towards developing London’s infrastructure in such a way that would cover all boroughs of the city, regardless of municipal governments. The Board of Works created a complex system of intercepting sewers, including fourteen pumping stations and two wastewater treatment plants (Bruce, 1969). Not only were the streets deodorized, they were also cleaner and starting to become more safe and hygienic, paved by granite and macadam. In addition, electric street lights were introduced around 1880 to modernize the urban experience. In a study of London’s transformation, urban technologies are explained as shaping London; â€Å"on the one hand, they could shield the eyes and ears of genteel urbanites from the offensive and barbarous workings of backstreet butchers. On the other, they enhanced the sensory vocabulary of London’s populations, first through gas lamps and later via electric lighting. † (Mort Ogborn, 2004). This concealment process was as effective for odour as it was for unsightly areas. Pooley (1984) talks about bus and tram routes which went through main streets lined with shops, by design hiding the unsanitary living courts below. He describes how a suburban dweller could then be oblivious to ‘unsightliness’: â€Å"the suburban dweller could thus avoid living in, and may even have been unaware of, the unhealthy districts with their polluted water supply, inefficient street cleansing, insanitary houses and all the other negative externalities associated with inner-city living. † These slums or rookeries were therefore to be cut off or cut out by the Metropolitan Board of Works street clearances and other public transportation schemes. Indeed, entire areas were pulled down in the hope to reduce poverty and restore cleaner air as well as increase visibility on social differences between classes. Unfortunately, though the long-term effect of this scheme was eventually successful, the immediate outcome is believed to have been very severe; â€Å"as land values rose, slum housing was demolished, forcing those with limited geographical mobility to crowd into adjacent neighbourhoods, thus continuing the cycle [of poverty]† (Baer, 1979). This ‘delocalisation’ entailed even further segregation between rich and poor in the modern city. A study of the distribution of the most poor, the paupers (who relied upon the Poor Law for survival), was carried out in an attempt to understand the development of pauperism. The results showed that â€Å"if the statistical curve of pauperism for 1881 be compared with that of 1891 [the] curve is sliding across from right to left [ ] showing that poverty breeds poverty, and the result of that breeding is ever growing concentrations of the poor† (Dorling Pritchard, 2009). This was most obvious in the residential patterns of Victorian cities, as stated by Canadine (1977), â€Å"segregation, which is much more widespread, is by status and income. The poor, whatever their occupation, huddle together on the edge of the central business district, whilst those with time and money to spare flee to the periphery. And between these extremes are the increasingly segregated lower and middle classes, in a variety overlapping zonal, sectorial and clustered residential patterns. † With this in mind, Firth’s painting is all the more powerful, skilfully representing the division of the classes between the wealthy and the destitute. Indeed, the painting seems split vertically: the boy, on the left side, with a broom in his hand, is complemented by another seemingly poor boy like himself in the carriage to represent London’s poor. The lady, on the right side, is looking in the opposite direction and contributes, along with the man walking away behind her, to creating the imagery of London’s wealthy, upper-middle class. The physical aversion to the scene by the gentleman and the lady could also translate a general social aversion of the rich towards the poor. At the time, it was believed by many that poverty was in the majority of cases self-inflicted; â€Å"the poor were expected to become ‘manly’; and ‘independent’ through the practice of thrift and self-help† (Baer, 1979). This controversy concerning a person’s capacity to disengage themselves from poverty was rife, not only among the rich, but throughout society. Figure 2 shows an example of a young boy blackening a client’s shoe. The photo, from Street Life in London by John Thomson and Adolph Smith, is followed by a detailed explanation of the shoe-blacking community which relied upon the freedom of the streets for survival. Within these workers were two parallel opinions: some boys believed the work should be reserved to children and exclude able-bodied adults who could perform another line of work; whereas others believed that a man should be free to choose whichever profession he pleased. However, regardless of the existence of these two beliefs, one prevailed, backed by the Metropolitan Police. The police force, created in 1829 in the context of London’s urban renewal and centralisation of the municipality, was henceforth able to influence the fate of street tradesmen. In the study of street life in London, policemen’s authority is clearly depicted explaining how certain policemen have been known to kick the boot-black’s box under a clients’ feet to prevent the blackener from working on the street without a licence. (Thompson Smith, 1877).

Federal Government Funding Enron Exploring Challenges

Government should have supported Enron, a large energy corporation, because the company advocated strict global regulations and followed the environmental principle of energy distribution (Carney, 2006). In addition, Enron have significant influence on the government in Washington, which is the second reason why the government should have supported this company. In particular, by providing financial support, the authorities could have taken greater control of bureaucracy and bribes.Advertising We will write a custom case study sample on Federal Government Funding Enron: Exploring Challenges specifically for you for only $16.05 $11/page Learn More At the same time, excess support of such large company as Enron could have hampered significantly the development of smaller businesses. In this respect, funding of Enron would have led to a shifted balance of small and big businesses. Another reason to withdraw funds allocation among big businesses lies in a po ssibility to support environmental and ecological reform because Enron would have had a direct impact on the polluted environment. Influence of Enron on Political Environment Enron actively engaged political leaders into their business activities to monitor the economic situation in the country (Milbank Kessler, 2002). In particular, close relationships political leaders – Bush and Lindsey – and Enron company can be considered the brightest example of the company’s political influence on the government. The case presented above discourages authorities to support big companies because they can also have a negative influence on a democratic system in the United States. Specifically, having influential people to support corporate activities provides a seed of misunderstanding between the US people and the government since the former strongly believes in transparency and equality in making political decisions. However, in case political power had supported big comp any’s initiate to advance economy, such as the example of supporting the Kyoto protocol for climate change, Enron would have had a good impact on the US development. Analysis of a Free Enterprise System The benefit of a free enterprise business lies in providing private owners with freedom of choices (Meyer, 1997). Free corporate systems and business groups often pursue their own interest rather than focus on global development. Therefore, they can significantly hamper the global integration of company into the globalization process. Shifts in production process and business management can lead to decreased control of the government of the trade market and, therefore, an enterprise system develops apart from the overall economic context in the United States. Moreover, it can significantly change the course of orientation and create an independent system of production.Advertising Looking for case study on business economics? Let's see if we can help you!

In particular, it succeeded in selling organic products and furnishing their hotel rooms with environmentally free items. Second, it has gained recognition on a global level and satisfied global requirements. Third, the company developed environmental partnerships with other related companies and programs. With regard to the above-presented case, the introduction of a global corporate citizenship provides an overview of new roles that free enterprise systems can perform at the international level. Therefore, encouraging global corporate citizenship development is appropriate because it contributes to enhancing ethical responsibilities and adhering to quality standards of production and service delivery. It also provides a solid platform for sustaining societal morale, ethics, and values by advancing such fields as political philosophy, international relations, and management studies (Anderson, 2010). Finally, it enables the companies to share experience with each other for creating of an advanced global community. References Anderson, R. (2010). Global Corporate Citizenship – A Trend to Watch.

A Guide to Homeschooling in North Carolina

A Guide to Homeschooling in North Carolina If youre considering homeschooling, learning the requirements of your state is one of the first steps. Homeschooling in North Carolina isnt complicated, but its important to understand how to get started and how to follow the law.   Making the Decision Deciding to homeschool your child is an incredibly significant decision and one that will certainly change your life. People decide to homeschool their children for many different reasons, some of which include: dissatisfaction with the public school system, desire to train their child within a specific religious framework, frustration with their childs current school situation, in order to meet a child’s special learning needs or wishing to keep a close family bond throughout the early school years. If you live in North Carolina, one or more of the other 33,000 families in the state who have already decided to homeschool one or more of their children may also influence your decision. Most everyone in North Carolina probably knows at least one family who has chosen to homeschool their kids. These families are wonderful sources of information and support as you make this important decision, and they can give you an honest appraisal of the ups and downs of committing to the homeschool journey. Following the Laws to Homeschool in North Carolina Homeschooling in North Carolina is not overly regulated, but there are a few edicts that everyone must follow. North Carolina does not require you to register your child as a homeschooler until he or she reaches the age of seven. Depending on the age your child is when you begin homeschooling, you may complete one or two grades before you even formally register your school. Approximately one month before your child reaches the minimum age, or one month before you plan to begin homeschooling an older child, a parent or guardian sends a Notice of Intent to the North Carolina DNPE. This Notice of Intent includes choosing your schools name and certifying that the primary supervisor of the homeschool has at least a high school diploma. Besides the requirement to file the Notice of Intent, North Carolina has the following other legal requirements for homeschooling in the state: Operating on a regular schedule  at least nine months out of the calendar yearMaintaining immunization records and attendance records for each child being schooled at homeAdministering a nationally standardized test to each child at least once per school yearMaking attendance, testing and immunization records available to the DNPE for examination each yearNotification to DNPE when deciding to terminate your homeschool A 180-day school year is recommended but not required. Deciding What to Teach The most important part of choosing what to teach your child is understanding exactly who your child is. Before you begin perusing curriculum catalogs and internet curriculum reviews, it is wise to find out how your child best learns. Learning style inventories and personality quizzes are abundant in most homeschooling resource books or on the internet, and these are wonderful for understanding how your childs mind works, and therefore which type of curriculum would be best for him or her. Families new to homeschooling quickly discover a dizzying array of choices when it comes to selecting a homeschool curriculum. There is no more popular discussion on the web than homeschool curriculum reviews by homeschool families. After sifting through the reviews, most parents end up mixing and matching homeschool curricula, trying to create the best match for their child. For families with more than one child, choosing a homeschool curriculum can even be more problematic. What works for one child may not work for another. What works for one subject may not work on the next. Experienced homeschooling families will tell you that there is actually no single, best homeschool material. Rather than feeling torn between homeschool resources, parents should feel free to select a diverse blend of materials and activities. Locating Resources Making the decision to homeschool your child and choosing the curricula you want to begin with are just a part of the homeschooling experience. The homeschool community has grown exponentially, and the resources available to homeschoolers now can seem endless in scope. Some common resources to investigate are: Online Homeschool mega-sites, such as NHEN or About Homeschooling for researching specific homeschool informationOnline homeschool forums and Facebook groupsHomeschooling magazines and newslettersOnline homeschool articles and blogsLocal or regional support groups, often including curriculum and resource sharing, as well as group field trips and outingsBooks about homeschooling from your favorite bookstore or local libraryStatewide homeschool organizations, such as NCHE, HA-NC, and NCAA whose goals are to support the rights and resources of those choosing to homeschool in North CarolinaHomeschool programs available through your local library, YMCA, 4H-Club, or Parks and Recreation Department Many museums, state parks, and businesses offer special classes and discounts for homeschool students. Check your local resources for opportunities available to you as a homeschooling family. Keeping the Dream Alive When your homeschooling adventure begins, everything is new and exciting. Your homeschool books smell like they came straight from the printer. Even lesson planning and record keeping seem more fun than a chore at first. But be prepared for the honeymoon phase to ebb and tide. No one has a perfect homeschool year, month or even week. It is important to intersperse your daily curriculum with field trips, play dates and  hands-on activities. North Carolina is full of  educational destinations  that are an easy day’s drive. Also, take advantage of your city’s visitor’s center or website to discover treasures in your own town that you might have overlooked. Whether you chose to homeschool from the beginning or came upon homeschooling accidentally, you are bound to experience slumps. It is almost certain that over time your homeschool will relax into something more familiar and predictable, but that is also the time when you usually notice that  this homeschooling thing  is more than just a passing phase. You have become one of the over 33,000 families in North Carolina who are proud to call themselves homeschoolers!

Sociological Theory in Sports Coursework Example | Topics and Well Written Essays - 2750 words - 1

Sociological Theory in Sports - Coursework Example Skinner, Zakus & Edwards (2005) posit that sociology theory may contribute to the discussion regarding the development of sport management practices and policies.   This essay aims to analyze the significance of sociology theory to sports management by studying modern sports issues.This paper is concerned with how sports play a role in fostering social inclusion to aid in social inclusion and community development. According to Coalter (2007), there have been two sports policies brought up: to increase social and sports participation trough geographically targeted programs in socially deprived locations and to emphasize the contribution that sports volunteering can make to activate citizenship.Relatively, sports sociology is still a new term. Chalip, Thomas & Voyle (1996) defines it as the study of â€Å"the sportsperson as a sociological being in a particular context† Giddens (1997). He also postulates that it includes the study of contemporary social models which influence sport, specifically those that have lasted. They also believe that sports sociology is morally bound to consider the process and results of inequality and ignorance that exist in sport. Sociology also allows the range of common beliefs practices and attitudes to be reviewed and analyzed with the sole purpose of giving the best quality of sporting experience to shareholders. Chalip, Thomas & Voyle (1996) discuss the value of the sociological theory relation in four areas: as a stimulus for new ideas, the ability to clarify or to destroy myths surrounding sports, theoretical or hypothesis testing in sports research, and allowing the explanation and generalization of the sport.In the past decade, sport and recreational policy makers have had to adjust globalization and neoliberal processes since they affect social, economic and state activities, including those of social and community development. The governments' methods to shift from support and financial provision for sport and oth er embedded liberalism provisions to modern neoliberal state ones resulted in significant changes Coalter (2007). In the â€Å"neo-liberal† state private-public partnerships, tax advantages for corporate social duty, and the reduction of social solidarity are key aspects of the new institutional frameworks.  According to Thompson (2004), this implies that development and community level sport should operate under market conditions and frameworks inherent in neoliberalism and globalism. This means that sport should fulfill two roles: traditional sport development system for society and elite sport programs; as a function of legislation, programs, policies, funding, and sports management, secondly, where a sport is employed as a platform to deal with issues in the society and offer opportunities for disadvantaged members of the society. Research proves that one of the biggest challenges facing the disadvantaged is to find a community which they can identify with and belong un der declining social program provision and persistent breakdown of social solidarity (Atherley, 2006).Long term reliability and sustainability in delivering social outcomes is essential to the success of these developments through sport participation programs. Modern society demands additional flexibility and choice. The challenge for the traditional sports sector in most places is to move beyond current sport delivery norms and provide a range of products at low cost locally developed opportunities and extended public, private and third sector social capital programs. According to Giddens (1997), there is always a risk relying on these predominantly volunteer organizations to determine social outcomes.In such as the United Kingdom, there is an opportunity for the organizations to establish long term programs to support the use of sport to engage the community to deliver positive social outcomes. Partnerships between the traditional sports organization and the community-based organi zations could be forged to support participation in sports across the time from outreach to mainstream participation (Atherley, 2006).
