Road condition data

A safety analyst wants to compare how well experienced and inexperienced drivers drive on three types of roads: paved, gravel, and dirt. To measure driving performance, the analyst records the time in seconds that each driver uses to make steering corrections on each type of road.

You can use this data to demonstrate Test for Equal Variances and Analysis of Means.
