Question:

The accompanying data set contains three variables, x₁, x₂, and x₃.

a. Create a new variable called “Difference” that contains the difference between the values of x₁ and x₂ for each observation (i.e., x₂ − x₁). What is the average difference?

b. Create a new variable called “PercentDifference” that contains the percent difference between the values of x₁ and x₂ for each observation (i.e., (x₂ − x₁)/x₁). What is the average percent difference?

c. Create a new variable called “Log” that contains the natural logarithms for x₃. What is the average logarithm value?
