Choose the most appropriate statistic for measuring spread for the following data sets.
a.) A medical survey asks for patients' body fat percentages. Most people in the study had body fat percentages in the 20's, while a few had body fat percentages over 40. Which is the best measure of the spread of body fat percentages?
range, proportion, standard deviation, IQR, median, or mean
b.) The same survey also asks for patients' heights. Which is the best measure of the spread of height?
range, proportion, standard deviation, IQR, median, or mean

There are 2 data sets below, choose which statistic to use and
conduct your analysis . This is
completely up to you but note that your data will dictate what test
you will run (see the book for examples and then compare to the
examples below). Be creative and thorough in your analysis. I will
expect 2 write-ups for both data sets.
Note: You will again need to use the tables in the back of the
book to determine significance....
