The One-Way Analysis of Variance (ANOVA) calculator computes the ANOVA F score and degrees of freedom for a number of groups. INSTRUCTIONS: Enter the following in comma separated lists: (OB) Observation Table of Groups (OC) Output Choice (F-Score or Details) ANOVA F-Score: The calculator returns the F-score and degrees of freedom for the null hypothesis. Note: there has to be an equal number of observations in the three groups. The calculator also returns the following support statistics: F Score Numerator: degrees of freedom Between: Denominator: degrees of freedom Within: Details Mean of Groups Grand Mean of All Groups Combined Sum of Squares (total) Sum of Squares (Within) Sum of Squares (Between) Variance Between Variance Within Example A school administrator want to know if the time / day of taking tests significantly affect test scores. Let's consider four groups of students taking pop quizzes. Group 1 only gets tested on Mondays first period. Group 2 only gets tested Wednesday after lunch. Group 3 only gets tested in the last period on Fridays, and Group 4 on random days and times. The quiz has 12 questions with a range of potential scores from 0 to 12.
