Step 1: Enter your data into the calculator. However, sampling statistics can be used to calculate what are called confidence intervals, which are an indication of how close the estimate p is to the true value p. The uncertainty in a given random sample (namely that is expected that the proportion estimate, p, is a good, but not perfect, approximation for the true proportion p) can be summarized by saying that the estimate p is normally distributed with mean p and variance p(1-p)/n.
