So, I’m not really good with statistics but I need some help in determining the sample size for my study. I want to do a pre-intervention/post-intervention study in the same group of people. In the study I would measure my outcome in the population before my intervention, then, in the same population, I would implement my intervention and measure the outcome then.

So I opened WinPepi to help calculate my sample size. I went to Compare2, opened Sample size, clicked on Change (using before-after ratings) and then input the parameters of my study and hit calculate.

The calculator than said that I need 1000 participants, 500 in each group. But according to the type of study I am trying to do, I would only need one group? Should I use a single group of 1000 or 500? Am I doing this all wrong?

Any help would be appreciated.
