based on this assignment: For this assignment, you will undertake an analysis based on a self-designed fictitious study that utilizes statistical methodologies. You will first develop a fictitious problem to examine - it can be anything. For example, maybe you want to look at whether scores on a standardized college placement test (like the SAT) are related to the level of income a person makes 10 years after college; Or, whether those who participate in a Leadership Training program rated as better managers compared to those who do not; Or, whether ones political affiliation is related to gender. These are just a few examples; be creative and think about what piques your interest. You might also address a problem that you may want to look at in future research for a dissertation. Your analysis report should include the following components: 1. Describe your research study. 2. State a hypothesis. 3. List and explain the variables you would collect in this study. There must be a minimum of three variables and two must meet the assumptions for a correlational analysis. 4. Create a fictitious data set that you will analyze. The data should have a minimum of 30 cases, but not more than 50 cases. 5. Conduct a descriptive data analysis that includes the following: a. a measure of central tendency b. a measure of dispersion c. at least one graph 6. Briefly interpret the descriptive data analysis. 7. Conduct the appropriate statistical test that will answer your hypothesis. It must be a statistical test covered in this course such as regression analysis, single t-test, independent t-test, cross-tabulations, Chi-square, or One-Way ANOVA. Explain your justification for using the test based on the type of data and the level of measurement that the data lends to for the statistical analysis. 8. Report and interpret your findings. Use APA style and include a statement about whether you reject or fail to reject the null hypothesis. 9. Copy and paste your data output and place it in an appendix. I want to use this data of improper payment root cause underpayment or overpayment data:

This document is a scientific hypothesis report in order to
investigate the “Climatic Changes” over past one decade. The
climatic changes have been very fast since the development and the
carbon emission rates have soaring high through out. The depleting
forest cover and the exhausts from the automobiles and the
industries have changed the temperature and the rainfall through
out the world. The Icebergs are melting and the level of the sea
water has been changing. There are a lot of climatic variations
introduced as result of the global warming.
Here in this report, we would not investigate the reasons and the
impacts of global warming but the point of investigation is to
analyze the changes in the temperature and the rainfall, from the
data related to the same. We would use many statistical means to
get to the conclusion.
2.
As discussed above, there have been a lot of climatic changes through out the century. We would analyze the scenario by using the data for the two cities of Kuwait and Melbourne. We gathered the data from the climate change portal of World Bank. The portal can be reached as http://sdwebx.worldbank.org/climateportal. We have provided the tables of the data collected in Appendix-I for Kuwait and Appendix-II for Melbourne.
Now, let us suppose the null hypothesis and the alternate hypothesis for the report as:
We would calculate the means of the temperature and update the hypothesis as we proceed through the results.
3.
Data Collection methods: This is the secondary data available to
us through a reliable and reputable source. Making primary data for
the temperature and the rainfall would have been a time taking
experience and the sample of the data collected would have lesser
variations as compared to the large population of the whole
century. So, we have collected the data from the historical part of
the site. The data can be found out by clicking on a particular
region.
Methods.
We would now, discuss the various methods we are going to use
for the project. The methods have been enlisted as follows:
1. The column charts help us in the comparison of data along the
identical horizontal axis.
2. The line graphs show us the rise and fall of the data along the
vertical axes in a more explicit way and let us compare the
variables between the two graphs.
3. Descriptive statistics give the values of different statistical
values related to the data.
4. One sample t-tests compares the means of the sample with
population and gives the reason whether to accept the null
hypothesis.
4.
We have made the column charts of the temperature (in degree Celsius) from the data available to us in the Appendix-I and Appendix-II. Similarly, we have made the line-chart of average rainfall of the two cities from January to December during the different periods which can be found from the chart titles above the graphs. It should be noted that we have taken two different vertical axes for each of the graphs shown here, the primary vertical axis for the temperature and the secondary vertical axis for the rainfall. However, we have only one horizontal corresponding to both the vertical axes, which gives the months of a year.
Appendix-I
The data for Kuwait has been presented in the following table.
Statistical data include the temperature (in degrees) and the
Rainfall (in mm).

Data Analysis is designed to build a strong foundation for development of statistical literacy and statistical thinking. Both are essential for business success and further studies in business. Recent research showed that “On average for 15-year-old Australian students, females achieved at a significantly lower level than male students (in mathematics)” (p.2, Buckley 2016)1 . However, there is also research evidence that “Despite the stereotype that boys do better in math and science, girls have made higher grades than boys throughout...

Assignment 3 Winter 2020 You will have a chance to analyze taxic response data using observational data from Planeria. You will use Pearson's chi square test which allows you to determine whether your planario are showing a taxic response to environmental variables. Pearson's chi-squared test is a statistical test applied to sets of categorical data to evaluate how likely it is that any observed difference between the sets arose by chance. It is the most widely used of many chi-squared...
