Survey Sample Size Determination Using SAS

Out of other options, I was wondering if I could calculate required sample size using #SAS for one of my surveys. Here are the details - population size: 6000; error tolerance: 5%; expected response rate: 25%; Confidence Interval: 95%. I know the answer but couldn't do it in SAS. Any help would be highly appreciated. Thanks, Ash

Re: Survey Sample Size Determination Using SAS

Read the SAS/STAT documentation about PROC POWER.  If your survey is a complex sample survey with design effects and respondent sampling weights, you'll have to consider the estimated design effect [=the ratio of the variance for the complex survey to the variance from a survey using simple random sample] possibly from previous, similar surveys.
