Mean and Standard Deviation of the Teacher salaries in 3 different regions

In this activity, you will be calculating the mean and standard deviation of teacher salaries data for 3 different regions located in the United States.  The standard deviation will tell us how far to the right or the left the teacher salaries are from the mean in the 3 different regions.

Using either Excel or the TI-83 graphing calculator, calculate the mean, median and mode for the entire data set including the 3 separate regions. Then, using either Excel or the TI-83 graphing calculator, calculate the standard deviation for the entire data set and the 3 different regions.

This data exists in two files; one is in Excel Data format, and the other is in Text format.

Comparing the 3 different regions, In which region would a teacher want to work in based on the mean value? What does the standard deviation reveal about the teachers salary data? In which region would the teacher salaries vary the most from the mean? Which region has the most consistent salaries?
