Question

Quizplus · Accepted Answer

Effect size is a measure of the magnitude of the difference between the means of the experimental and control groups. It is calculated by dividing the difference between the means by the standard deviation of either group. It provides an estimate of the practical significance of the results, beyond statistical significance, and can be used to compare the effectiveness of different interventions or to determine the sample size needed for future studies. Between-groups variance (A) and within-groups variance (B) are components of variance used in ANOVA to determine the main effects and interactions between variables. Power (D) is the probability of detecting a true effect, given a specific sample size and level of significance.
