Mean Square Treatments (MST)

A measure used in analysis of variance (ANOVA) to evaluate the variance within treatment groups, helping to identify whether differences between groups are statistically significant.

Test Statistic

A statistic calculated from sample data, used to decide whether to reject the null hypothesis in hypothesis testing.

Within-treatments Variation

The variability among experimental units that are exposed to the same level of treatment in an experiment.
