search for: proporion

Hello, I have several ordered groups (20), each with several observations. Each group has fewer observations roughly linearly from 30 to 0. Each observation is a proportion. As I know the max and min values for a proporion are 1 and 0, I am adding these values to each group to allow bootstrap for groups with <= 1 observations. Sometimes the bootstrap confidence interval is > 1, which makes me think that I am doing something deeply wrong. How can I do bootstrap properly with observations which are proportions?...
