Question: 1. Calculate the mean, median, standard deviation, the first quartile, the third quartile and the IQR. Round to one decimal place.
2. Construct a box plot for the FTES for 2005-2006 through 2010-2011 and a box plot for the FTES for 1976-1977 through 2004-2005.
3. Compare the IQR for the FTES for 1976-77 through 2004-2005 with the IQR for the FTES for 2005-2006 through 2010-2011. Why do you suppose the IQRs are so different?
