Experts,

I have 14,00 records which I have calc;ulated a percentage.  How canI calculate the mean percentage of these records and then the standard deviation.  I am not sure if this is correct.  If possible I would like to  select all of those where the standard deviation is greater than 2 times the standard deviation.

I would like to do this in SAS.   Any ideas!!

Hi

Assuming your database is called "dsname" and the percentage variable name is "perc1" then

proc sql;
  create table test2 as
    select * from dsname
	having Perc1 >= mean(Perc1)+2*std(Perc1);

To calculate the mean and std dev use:

proc sql;
  create table test2 as
    select mean(perc1) as MeanPerc, std(Perc1) as StdDevPerc from dsname
;
