Calculate the skewness for your data set using Pearson's
Skewness Formula:
Skewness = 3 * (Mean - Median) / SD
And also determine all three (3) quartiles.
Test the Empirical Rule on your data set by finding the answers to the following questions:
(A) What percentage of YOUR data values lies within one (1) SD-unit of the sample mean?
