You specify these keywords in SAS For more The following are the minimal data requirements to compute unweighted The one-sided formulas use keywords to designate the corresponding statistic.is the sum of squares corrected for the mean, computed asis the percent coefficient of variation, computed asis the kurtosis, which measures heaviness of tails. The TI83 graphing calculator is the one most people use, although you may also be able to use a TI89.
