Question

Quizplus · Accepted Answer

Nelson's h statistic is a measure of effect size for ANOPs. It is calculated by dividing the difference between the proportions of two groups by the square root of the sum of the proportions. The sample size per group used to obtain Nelson's h statistic should be as large as possible, as this will increase the precision of the estimate. In practice, a sample size of at least 30 per group is recommended.
