Project on using MS-Excel in descriptive analysis of data: Assuming that you have conducted a survey in a company for a sample of at least 50 employees, you collected data about employees’ job title, academic qualification, years of experience, and salary of the employee (four variables). Required: a. Input the data about the four variables in MS-Excel sheet. b. Prepare frequency distribution tables for the variables. c. Prepare appropriate graph for each of the frequency tables. d. Prepare a pivot table (cross tabulation) for the two qualitative variables. e. Conduct descriptive analysis for the two quantitative variables (summary measures). f. Find the coefficient of variation (CV) and compare the dispersion of the two quantitative variables.

A statistics content developer at Aplia wanted to know whether study skills are related to memory quality. She invited student volunteers to perform an online memory task. The students saw a list of 60 words and were then asked to recognize a list of 10 words that were on the original list. Students were also asked to provide their GPAs. Consider the following data set, which was collected from student volunteers in 2009. The table gives the frequency for five intervals of scores on the number of correctly identified words. Use the dropdown menus to complete the table by filling in the missing values for the proportions and percentages. Score Interval f Proportion Percentage 9–10 29 0.19 19% 7–8 53 5–6 50 3–4 22 0.14 14% 1–2 1 0.01 1%
A marketing firm is doing research for an Internet-based company. It wants to appeal to the age group of people who spend the most money online. The company wants to know if there is a difference in the mean amount of money people spend per month on Internet purchases depending on their age bracket. The marketing firm looked at two age groups, 1818-2424 years and 2525-3030 years, and collected the data shown in the following table. Let Population 1 be the amount of money spent per month on Internet purchases by people in the 1818-2424 age bracket and Population 2 be the amount of money spent per month on Internet purchases by people in the 2525-3030 age bracket. Assume that the population variances are not the same.
