|---|
| Bonferroni adjustment | Setting a more stringent alpha level for multiple tests to minimize Type I errors |
| ANOVA (analysis of variance) | An inferential statistical test for comparing the means of three or more groups |
| one-way randomized ANOVA | An inferential statistical test for comparing the means of three or more groups using a between-participants design and one independent variable |
| grand mean | The mean performance across all participants in a study |
| error variance | The amound of variability among the scores caused by chance or uncontrolled variables |
| within-groups variance | The variance within each condition; an estimate of the population error variance |
| between-groups variance | An estimate of the effect of the independent variable and error variance |
| F-ratio | The ratio between-groups variance to within-groups variance |
| total sum of squares | The sum of the squared deviations of each score from the grand mean |
| within-groups sum of squares | The sum of the squared deviations of each score from its group mean |
| between-groups sum of squares | The sum of the deviations of each group's mean from the grand mean, multiplied by the number of participants in each group |
| mean square | An estimate of either variance between groups of variance within groups |
| eta-squared | An inferential statistic for measuring effect size with an ANOVA |
| post hoc test | When used with an ANOVA, a means of comparing all possible pairs of groups to determine which ones differ significantly from each other |
| Tukey's honestly significant difference (HSD) | A post hoc test used with ANOVAs for making all pairwise comparisons when conditions have equal n |
| one-way repeated measures ANOVA | An inferential statistical test for comparing the means of three or more groups using a correlated-groups design and one independent variable |
