By default, PROC TTEST uses the most recently created SAS data set. The input data set can contain summary statistics of the observations instead of the observations themselves. The number, mean, and standard deviation of the observations are required for each BY group (one sample and paired differences) or for each class within each BY group (two samples).

Oct 28, 2018 · If you don't know what a level is, how can you even consider doing a T-test? That's what a t-test does, it compares the means of two different levels (conditions, settings, etc.) of a variable (in this case WEIGHT_STATUS) in your data. You can check the levels in any number of ways; by doing a PROC PRINT or a PROC FREQ on the variable WEIGHT_STATUS.

The dollar sign ($) following Gender in the INPUT statement indicates that Gender is a character variable. The trailing at signs (@@) enable the procedure to read more than one observation per line. You can use a group test to determine whether the mean golf score for the men in the class differs significantly from the mean score for the women. If you also suspect that the distributions of the ...

Try thinking of it as akin to the syntax used to specify a data set in a SAS procedure. In the DATA= option, the OUT= option, the OUTEST= option, etc,the name of the data set is specified on the right.
