In conducting a simple linear regression analysis, an R2 of 0.72 is obtained. This results in an F-value of 1027 and a p-value that is less than 0.0001.
 
  During a final check of the model, it is noticed that the distribution of the residuals is highly positively skewed. What does this mean?

Question 2

The range is an ideal measure of variation since it is not sensitive to extreme values in the data.
 
  Indicate whether the statement is true or false

Answer to Question 1

It means that though the linear model explains the relationship quite well, the linear model may not be the best model to apply. In fact, the highly positive skew suggests that the relationship might actually be exponential in nature. Exponential relationships look linear at the lower values.

Answer to Question 2

FALSE
