Variance in SAS

  1. Mar 2, 2008 #1
    1. The problem statement, all variables and given/known data

    Howdy I got a datasheet in the SAS data system with 3 variables and 60 obs.

    How do I most simply get SAS to calculate the variance?

    2. Relevant equations

    3. The attempt at a solution

    data cnn;
    input vara varb snt@@;

    proc sort;
    by vara;
    proc means;
    by vara;

    Which code to I add to get it to calculate the variance of the three vars??

    Thanks in advance
