Test Statistic

A numerical figure derived from sample data for the purpose of testing a hypothesis within the field of statistics.

Randomized Block

A design in experiments where the experimental subjects are first divided into blocks based on external factors that might influence the results, and then randomly assign treatments within each block to minimize variability.

Analysis of Variance

A statistical method used to test differences between two or more means by analyzing variance among and between groups.

Sign Test

The Sign Test is a nonparametric test used to determine if there are significant differences between the medians of two paired samples.
