Since you mention SAS, lookup the documentation for PROC MEANS, the FREQ
statement ...
"specifies a numeric variable whose value represents the frequency of the
observation. If you use the FREQ statement, the procedure assumes that each
observation represents n observations, where n is the value of variable. If
n is not an integer, the SAS System truncates it. If n is less than 1 or is
missing, the procedure does not use that observation to calculate
statistics.
The sum of the frequency variable represents the total number of
observations."
