This calculator computes the F-statistic and an approximate p-value for a one-way ANOVA, given the sum of squares between (SSB), sum of squares within (SSW), and their respective degrees of freedom. Enter SSB, dfBetween, SSW, and dfWithin to obtain the F-statistic and p-value. Results are for educational and preliminary use only.

This calculator will tell you the minimum sample size required for a hierarchical multiple regression analysis; i.e., the minimum sample size required for a significance test of the addition of a set of independent variables B to the model, over and above another set of independent variables A. The value returned by the calculator is…
Use this calculator to estimate the Beta (Type II Error Rate) in your hierarchical multiple regression analysis. By inputting the number of predictors, effect size, sample size, desired power, and alpha level, you can understand the likelihood of failing to reject the null hypothesis when it is false. For critical decisions, verify results with professional…
