A statistical method for comparing three or more group means by analyzing variance between and within groups. Variance Between Groups
A measure of how far apart group data values are, indicating differences among group means. Variance Within Groups
A measure of data spread within each group, reflecting how similar or diverse individual group values are. F Statistic
A ratio of variance between groups to variance within groups, used to assess if group means differ. Null Hypothesis
A statement asserting all group means are equal, forming the basis for statistical testing in ANOVA. Alternative Hypothesis
A statement suggesting at least one group mean differs from the others, opposing the null hypothesis. Degrees of Freedom
Numerical values used in ANOVA calculations, based on the number of groups and total observations. P Value
A probability indicating the strength of evidence against the null hypothesis, compared to alpha. Alpha
A threshold for statistical significance, commonly set at 0.05, guiding decision-making in hypothesis tests. F Distribution
A probability distribution used in ANOVA for evaluating the F statistic and determining significance. Random Sample
A selection method ensuring each member of the population has an equal chance of being chosen. Independent Sample
A group where the selection or outcome of one member does not affect others, crucial for ANOVA validity. Normal Distribution
A bell-shaped data pattern assumed for populations in ANOVA, supporting reliable statistical inference. Equal Variances
A condition where group populations have similar variability, required for accurate ANOVA results. Critical Value
A cutoff from statistical tables used to compare with the F statistic to decide on hypothesis rejection.
