Use the Table below to answer the following questions. Descriptive Statistics for Monthly Sales in 1000s by Month For 3 Dealerships (2007-20011) Which dealership had the highest sales? Which dealership has the most consistent sales?

Solution

a)

When it comes to \"highest sales\", we look at the mean.

Southlawn has the highest sales. As you can see, it has the highest mean of 378.

b)

When it comes to \"consistency\", we look at the standard deviation and range, which both measure variability. The lower these values are, the more consistent it is.

Here, the most consistent, therefore, is Eastville, as it has the lowest standard deviation and range among the three.
