Finding Chi-Square Functions in Excel

Statistics is a subject with a number of probability distributions and formulas. Historically many of the calculations involving these formulas were quite tedious. Tables of values were generated for some of the more commonly used distributions and most textbooks still print excerpts of these tables in appendices. Although it is important to understand the conceptual framework that works behind the scenes for a particular table of values, quick and accurate results require the use of statistical software. There are a number of statistical software packages. One that is commonly used for calculations at the introductory is Microsoft Excel. Many distributions are programmed into Excel. One of these is the chi-square distribution. There are several Excel functions that use the chi-square distribution. Details of Chi-square Before seeing what Excel can do, let’s remind ourselves about some details concerning the chi-square distribution. This is a probability distribution that is asymmetric and highly skewed to the right. Values for the distribution are always nonnegative. There is actually an infinite number of chi-square distributions. The one in particular that we are interested in is determined by the number of degrees of freedom that we have in our application. The greater the number of degrees of freedom, the less skewed our chi-square distribution will be. Use of Chi-square A chi-square distribution  is used for several applications. These include: Chi-square test—To determine if the levels of two categorical variables are independent of one another.Goodness of fit test—To determine how well-observed values of a single categorical variable match with values expected by a theoretical model.Multinomial Experiment—This is a specific use of a chi-square test. All of these applications require us to use a chi-square distribution. Software is indispensable for calculations concerning this distribution. CHISQ.DIST and CHISQ.DIST.RT in Excel There are several functions in Excel that we can use when dealing with chi-square distributions. The first of these is CHISQ.DIST( ). This function returns the left-tailed probability of the chi-squared distribution indicated. The first argument of the function is the observed value of the chi-square statistic. The second argument is the number of degrees of freedom. The third argument is used to obtain a cumulative distribution. Closely related to CHISQ.DIST is CHISQ.DIST.RT( ). This function returns the right-tailed probability of the selected chi-squared distribution. The first argument is the observed value of the chi-square statistic, and the second argument is the number of degrees of freedom. For example, entering CHISQ.DIST(3, 4, true) into a cell will output 0.442175. This means that for the chi-square distribution with four degrees of freedom, 44.2175% of the area under the curve lies to the left of 3. Entering CHISQ.DIST.RT(3, 4 ) into a cell will output 0.557825. This means that for the chi-square distribution with four degrees of freedom, 55.7825% of the area under the curve lies to the right of 3. For any values of the arguments, CHISQ.DIST.RT(x, r) 1 – CHISQ.DIST(x, r, true). This is because the part of the distribution that does not lie to the left of a value x must lie to the right. CHISQ.INV Sometimes we start with an area for a particular chi-square distribution. We wish to know what value of a statistic we would need in order to have this area to the left or the right of the statistic. This is an inverse chi-square problem and is helpful when we want to know the critical value for a certain level of significance. Excel handles this sort of problem by using an inverse chi-square function. The function CHISQ.INV returns the inverse of the left tailed probability for a chi-square distribution with specified degrees of freedom. The first argument of this function is the probability to the left of the unknown value. The second argument is the number of degrees of freedom. Thus, for example, entering CHISQ.INV(0.442175, 4) into a cell will give an output of 3. Note how this is the inverse of the calculation we looked at earlier concerning the CHISQ.DIST function. In general, if P CHISQ.DIST(x, r), then x CHISQ.INV( P, r). Closely related to this is the CHISQ.INV.RT function. This is the same as CHISQ.INV, with the exception that it deals with right-tailed probabilities. This function is particularly helpful in determining the critical value for a given chi-square test. All we need to do is to enter the level of significance as our right-tailed probability, and the number of degrees of freedom. Excel 2007 and Earlier Earlier versions of Excel use slightly different functions to work with chi-square. Previous versions of Excel only had a function to directly calculate right-tailed probabilities. Thus CHIDIST corresponds with the newer CHISQ.DIST.RT, In a similar way, CHIINV corresponds to CHI.INV.RT.

Critical Response Paper Free Essays

The development of political thought was always close-knit with the author’s epoch and regime of governance he lived under; however, in spite of the ethical and technological limitations, associated with the temporal factor, the majority of political scientists sought to build a universalized framework of justice and legitimate state power. John Rawls is distinguished for his positivist, or â€Å"realistic utopian† approach to justice and principles of peaceful coexistence among individuals as well as peace between government and population. However, the proportion of utopianism is much higher in his writings, as compared to the realism ratio, given that he fails to address the challenges, related to diversity and class inequality which are dominating the modern North American society. We will write a custom essay sample on Critical Response Paper or any similar topic only for you Order Now First of all, it is important to pay attention to Rawls’s dynamic and positivistic model of justice. According to the article, instead of seeking the ideal of justice beyond the existing order of affairs, the scholar tries to enable reasonable and gradual improvements of the internal structure and situation: â€Å"We can see this idea through the rather well-worn metaphor of the difference between the efforts needed to fix a boat that is at sea one plank at a time rather than trying to rebuild it from scratch. Generally speaking, it makes more sense to engage the first sort of repair job than a complete rebuild† (Mini-lecture, p.4). Interestingly, the author focuses predominantly on the strong points of the current ideas of justice as articulated both in legal terms and through societal behaviours. However, this task might appear extremely challenging given the focus of diversity in most European and North American policies. Diversity is a delicate issue, since there is a number of conflicts among beliefs, interests and practices, underlying each cultural or social group. Obtaining true impartiality also turns into a difficult task, as the society, which lacks uniformity in certain vital political issues, is likely to encourage its groups to perceive and assess the objective reality from the intragroup value system; as a result, such judgments can seem neither objective nor neutral. According to the article, â€Å"He does not propose a vision of justice that would stretch our character too and tries to build a theory that is responsive to our current conditions† (Mini-lecture, p.5). However, taking into consideration the above provided chain of reasoning, one can assume that the existing disproportion and divergence of political values will inevitably result in the necessity of â€Å"stretching† the philosophies or ideologies of certain minority groups, either religious or cultural. However, for the purpose of maintaining/ establishing social cohesion, this step can be justified, since the vast majority is likely to benefit from it. This excessive pluralism is partially addressed in the reading: â€Å"Bearing this point in mind, he tries to find a way to build an impartial model for deliberating about principles of justice that everyone can reasonably be expected to endorse despite holding different religious and moral views† (Mini-lecture, p.5). The statement is quite abstractive, whereas the particular scenarios of its realization point to the existence of disparities in core values of each group. For instance, in the United States, there are several large Muslim communities, whose polity greatly resembles the lifestyles of Middle Asian societies. The U.S.-based communities might engage with political activity and unite into a faction, requiring, for instance, the cancellation of women’s right to take certain jobs, and referring to the fact that the existing state-of-art offends their vision of gender morality. Surprisingly, this faction might be supported by other political groups, which also share this view on gender equality – as a result, the society might be torn by the debate over the true justice. As one can notice, the representation of the core values of liberty might be uneven in our society, so both federal and state legislations necessarily challenge the beliefs of a certain minority.   Furthermore, Rawls’s concept of justice and stability is quite unrealistic, since it provides an abstractive picture, barely imaginable in the current world. According to the political philosophy article, â€Å"His core insight is that a stable and enduring society is one that is also just, that is, where citizens are considered to be free and equal. More importantly, citizens have to be able to see themselves and each other as free and equal† (Mini-lecture, p.6). However, inequality is inescapable, it is often referred to as an engine of social and political development, which motivates individuals to participate in political processes. The true equality, as articulated in the paper, consists in people’s outlooks and convictions, yet the formation of â€Å"equality beliefs† is normally realized only partly, since there still exist economic, social, regional, gender and age boundaries which make people feel underprivileged or superior. In this sense, Rawls refers to Kant and observes that the greatest political ideas were realized from the personal to the public, i.e. if an individual considers certain pattern ‘fair’, this pattern is likely to appear to be ‘fair’ in the whole society. However, this logic of reasoning fails to take into consideration the fact that the idea of equality was first born in autocratic societies, bearing much higher uniformity within its aristocratic and power circles, as compared to the modern Western world. Given that Rawls himself states that the relevance of political ideas depends on temporal and spatial (regional) factors, so the ideas of liberty and equality, which existed in the ancient world and Enlightenment society, are not fully suitable in the modern North American society. Thus, given that the author implies a positivist approach o the development of political values and proposes that they be formulated â€Å"from within†, Rawls should have also looked closely at specific cases and considered the workability of his perspective in real macrogroup situations.

Segmentation Motivation Rural Tourism Activities †MyAssignmenthelp.co

Question: Discuss about the Segmentation Motivation Rural Tourism Activities. Answer: Introduction The main purpose of these two discussion papers is to recognize and analyze the importance of rural tourism in two different areas and to see what are the similarities and the differences in the path of the propagation of the same in both the areas. It is seen from the two discussion papers that rural tourism is one of the most rather the most important activity for promoting economic development on the rural regions, it not only encourages the development of the rural economy but also the using up of the lost working places. There are usually several links that one can find between ecotourism and rural tourism as the main purpose is to uplift the rural areas economically, socially and culturally also keeping in mind the environmental aspects of the rural regions. Problem definition- The main problem that were identified was the poor economic condition of the rural areas and also the loss of the cultural heritage, the natural uplifting of the rural regions and the different challenges that might be faced in developing the rural areas through rural tourism. Agenda setting- It is the first step where issues come before the eyes of the Government and are also labelled as matters of utmost importance that are in need of government attention. This can be linked easily to the issue of the development of rural tourism as well. (Saarinen Lenao 2014, p.363-372). Policy formulation- The finding out of several alternative measures that could deal with the problem of sustainable development existing in the rural areas. (Komppula 2014, p.361-371). Hence, attempts were made in order to frame and formulate policies for the sustainable rural development and rural tourism. Decision making-Government took the necessary decisions that are essential for the purpose of solving the problems that are persistent in the rural economies, and finding out the solutions and the process in which those solutions must be implemented. It includes conducting interviews with the local people including the villagers and also the farm owners about the changes that they have faced recently or the advantages and disadvantages that they have to come across from this rural tourism development in their areas. Eurobodalla Shire, known as the land of many seas richly adorned with the coastal beauty of oysters, orchids, sea creatures and the pure sea breeze is a local eco tourist spot located in NSW region of Australia. As records suggest, the urbanization rate has increased a lot during the past few years and it is mainly because of the lack of proper educational and employment opportunities. Hence, in order to solve this problem, the agenda set was to train the local people about the usefulness of this project and also providing them with better employment opportunities so that the chances of migration is reduced. Several policies were made for the proper implementation of the rural development methods, some of it was exercised but it was seen from the policy evaluation system that there were still chances of migration due to the lack of proper training and awareness and rural tourism developmental activities often clashed with the local agricultural practices. Alpine Shire also is a new endeavor made towards the development of the rural tourism. It has been recognized as the most versatile and valuable cultivable land of the NSW region of Australia. The agenda set to develop this place as a rural tourist spot was almost similar to that of Eurobodalla Shire, but the policy setting and policy implementation has been done in a better way and is seen to be much more successful. It has used Agri Tourism as one of its main promotional activity which has not only attracted a huge number of customers but also has created a good market for the local products. To begin with both Alpine Shire and Eurobodalla Shire mainly attract the tourists based on the scenic beauties and the view of the beautiful rural landscape. As is seen from both the discussion papers, rural tourism is a very modern concept that has emerged in the recent times that is over the past few years with a very positive approach. It is so because the main motto of rural tourism development is to promote sustainable economic growth in the remote, rural and economically backward regions. Rural tourism brings along with it a huge scope for opening up many new job opportunities for the rural local people (Randelli, Romei Tortora 2014, p.276-281). As it was decided that the rural tourism development project will be undertaken in these regions, a large number of villagers had to be trained and properly educated so that they have no difficulty in understanding the whole area of changers that would be taking place around them (Rid, Ezeuduji Prbstl-Haider 2014, p.102-116). As there are very frequent cases of sudden closure of the mining and other factories, the villagers often lose their jobs and are forced to leave and migrate from the villages, but with the arrival of this project of rural development, these villagers once again got several new employment opportunities (Saarinen Lenao 2014, p. 363-372). A group of the local villagers were trained with a special art of tree cutting which was needed to create the exteriors and the surrounding gardens of the tourist lodges and the resorts, as a result of which these localities got appointed in a new job role and they could in turn train more number of villagers to work with them but even after promoting these employment opportunities, there have been several cases of migration because many villagers were unable to understand this whole new concept and lacked the patience and the will to adapt to these changes(Jepson Sharpley 2015, p.1157-1178). They have also made sure that there is a strong market that promotes and sells the local handmade products to the tourists (Calabr Della Spina 2014, p.43-48) similar strategies have also been undertaken in Eurobodalla Shire as well, but still many villagers have left the village, perhaps because of the lack of a strong market and also because of the lack of proper training programs to inculcate among them the usefulness of the rural tourism. On contrary, Alpine Shire has a different picture. It not only conducts several training and awareness programs but also a large number of events like annual fairs where many people gather in order to by the local products, thus giving a boost to the rural economy and giving them a global platform to expand (Hernndez-Maestro Gonzlez-Benito 2014,p.83-95). At the same time there has been the identification of some issues in the Eurobodalla Shire, like there has been a clash between the agricultural activities and the tourism developmental activities (Jepson Sharpley 2015, p.1157-1178). As there are many cultivable lands located in and around the tourist spot, the local farmers fear that their farmlands might be harmed due to the tourist spot developmental activities (Cornet, 2015,p.29-43.). On contrary, one can notice that Alpine Shire has promoted Agri-Tourism, by the means of which, they have opened a new and unique arena for the visitors to develop a keen interest in visiting those places from where their food comes and also see the processes involved in the food production. Moreover, Alpine Shire has an additional advantage as it has been identified as the most versatile agricultural lands of Australia, with fertile soil, moderate rainfall, and fresh air altogether making it a refreshing and ideal place for the tourists. Now coming back to Eurobodalla Shire, another challenge faced is the waterway maintenance and the supply of clear potable water to the local residents and the tourists. As ecotourism is mainly based on the preservation of the cultural heritage, there must be the proper maintenance of the Shires heritage as well, particularly in the rural areas which in turn will increase the opportunities for tourism. Alpine Shire on one hand has promoted rural tourism and on the other hand has also opened for many new job and education opportunities for the villagers, as it conducts many seminars and education programs for the local people to develop knowledge on the production of new innovative products. Similarly, both these places have been successful in providing the tourists with all the necessary facilities related to their accommodation and the site seeing as well. A large number of natural sites seeing like parks, national parks, bird watching, horse riding etc have been set up. But it is also evident from the two discussion papers that, there are still some areas of improvement on which the endeavors of rural tourism have to work upon in the future days. I have been able to enrich my knowledge a great deal through this analysis regarding the ecotourism and also the different steps involved in preserving and improving the social, cultural and the ecological aspects of the rural tourist spots. Being a part of the tourism industry, this research has helped me immensely to understand about the two beautiful ecotourism spots of Eurobodalla and Alpine Shires which are gradually becoming the favorite ecotourism spots. I find that this present scenario is the scenario of change and diversity (Phillips et al., 2013, p.93-104). It is a time when the customers are more inclined towards something new and something very unique, in other words, they like to think our of the box. In order to spend their holidays, most of the customers are looking for a calm, quiet, peaceful and refreshing place. This analysis of the rural tourism will now help me to easily reach out to my targeted customers and thus develop a strong customer base. Conclusion These regions might be rural in terms of economy and their geographic locations but at the same time; they are richly adorned with natural beauty. In other words, these regions have a great potential for economic development if they are given proper financial aids and are properly managed through the proper channels. As tourism industry is a labor intensive industry, hence it can at once open a huge plethora of opportunities for these economically weak backward regions. Though it is a very newly emerging concept at the same time, it is a plethora of opportunities. The Government must be more active towards the uplifting of the rural tourist spots with new and helpful laws and policies. Reference list Butler, R., 2014.
