Hi everyone. I made this post but realized that I may have left out some vital information. I have a data of about 300 observations (sch) from which I want to draw a sample of 100. I've used the proc surveyselect for the simple random sampling but I now want to do a stratified sample because my simple random sample gives me more of high SES (1) and I want the sample to have equal representation of each SES and each county.

Sch SES County Rate1 Rate2 Rate3 Rate4
AAG 2 cga 0.39 0.63 0.39 0.63
ALB 1 rls 0.00 0.28 0.00 0.28
OCA 2 tbe 0.43 0.18 0.43 0.18
APl 1 dce 0.10 0.35 0.10 0.35
AYD 1 ffe 0.25 0.34 0.25 0.34
AAL 1 lle 0.14 0.35 0.14 0.35
AEY 1 ctt 0.12 0.57 0.12 0.57
