Fitting data to distributions
... A probability distribution describes the probability of each measure. Statisticians have described several theoretical probability distributions that can be mathematically described by parameters such as mean and ...

Estimation with Confidence Intervals
... Generally the variance of the population under study is unknown. As a result s has to be estimated. The most common sources of estimates for s are: 1. A pilot sample which is drawn from the population and used as an estimate of s. 2. Estimates of s from previous or similar studies. 3. In a normally ...
