Creating treatment and control group

[sherry88]

Hi,

I would like to get advice on how can I create a 2 treatment and 1 control group with 95% confidence/5% margin error in SAS

Thanks

Can you please describe the experiment in a lot more detail? Could you provide a few more details about what you want to do?

Which of the following do you want?

1. You have study participants and you want to randomly allocate each participant to either the Treatment1 group, the Treatment2 group, or the control group.  If so, use PROC SURVEYSELECT.

2. You have a response variable for each of the three groups and you want to estimate the mean response in each group, along with 95% CIs for the mean? If so, use PROC GLM for a fixed effect model.
