Statistics are sometimes used to compare or identify authors of different works. The lengths of the first 20 words in the foreword by Tennessee Williams in Cat on a Hot Tin Roof are listed along with the lengths of the first 20 words in The Cat in the Hat by Dr. Seuss. Does there appear to be a difference in variation?

Find the range and standard deviation for each of the two samples and then compare the two sets of results.
