The research firm LL Research collected data from 200 client businesses. They want to determine how the businesses compare among four variables: 2015 Profit in millions of dollars 2016 Profit in millions of dollars 2015-2016 Two-Year Change in Daily Average Customer Visits Two-Year Average Number of Employees Data collected for the sample of 200 businesses is contained in the file named Businesses, linked at the bottom of the page. Be sure to use all 200 data points. Managerial Report Prepare a report (see below) using the numerical methods of descriptive statistics presented in this module to learn how each of the variables contributes to the success of a client’s business. Be sure to include the following three items in your report. Compute descriptive sample statistics (mean, median, two quartiles Q1 and Q3 (using QUARTILE.EXC), minimum, maximum, range, interquartile range, sample standard deviation, and coefficient of variation) for each of the four variables along with an explanation of what the descriptive statistics tell us about the client businesses. In this case, which measure of central tendency would be best for this application? Explain why. Which measure of variation would be best for this application? Explain why. How can one use the above descriptive statistics to understand the businesses better? Which graphical displays of data would you use to help understand or complement the above descriptive statistics? Explain how and why. Compute the percent change in profit from 2015 to 2016 for each business. What would the percent change tell us in this application? Then use the z-score to determine which businesses were outliers with respect to percent change in profit. How would identifying outliers be useful in this application? What advice might you give to businesses that are outliers? How else would you determine outliers? Compute the sample correlation coefficient, showing the relationship between percent change in profit and each of the other two variables (2015-2016 Two-Year Change in Daily Average Customer Visits and Two-Year Average Number of Employees). Explain what the correlation coefficients tell us about the three pairs of relationships. Use tables, charts, or graphs to support your conclusions. 

For this Assignment, you will examine the one-way ANOVA based on a research question.To prepare for this Assignment:Review this week’s Learning Resources and media program related to one-way ANOVA testing.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.Based on the dataset you chose, construct a research question that can be answered with a one-way ANOVA.Once you perform your one-way ANOVA analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 2- to 3-paragraph analysis of your one-way ANOVA results for your research question. Do not forget to evaluate if the assumptions of the test are met. Include any post-hoc tests with an analysis of the strength of any relationship found (effect size). Also, in your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output.Required mediaLaureate Education (Producer).
