An Introduction to Statistics and Data Analysis Using Stata

Chapter 6 Exercise 2

2. Using the data set that you created from Exercise 1 in Chapter 4 (about

binge watching television), follow the instructions below.

a. Identify both the variable type and scale of measurement for each of the

four variables (TV Source, Hours per week, Binge frequency, and Sex) in

your data set.

b. What is the mode for Binge frequency? Show your Stata command and

output as part of this and for all following answers.

c. What is the 25th percentile value for Hours per week? Explain what

this means in words.

d. What is the variance for Hours per week?

e. Make a table that shows Sex in the rows and the mean and median of

Hours per week in the columns. Format the table so that there are no

numbers to the right of the decimal point. In other words, use only whole

numbers.

f. Calculate the coefficient of variation for Hours per week (use a

calculator for this after obtaining the numbers that you need).

g. Generate a cross tabulation of Sex and Binge frequency. Be sure to

think about whether the rows or columns should add up to 100%. Based

on your table, what percentage of women binge watch frequently and

what percentage of men binge watch frequently?

h. Generate a bar chart that shows the average Hours per week that men

and women binge watch TV.

i. Generate a histogram of Hours per week.

j. Generate a pie chart of Binge frequency. Label each slice of the pie with

the percentage value.
