F Statistic

A ratio of variances used in the analysis of variance (ANOVA) to assess the significance of the difference between group means.

Least Squares Regression

A statistical method used to determine the line of best fit by minimizing the sum of squares of the differences between observed values and those predicted by a linear model.

P-value
