Question: Define the primary purpose of an ANOVA table in psychological research, and list the six standard types of values or components that are typically organized and reported within its columns.
Sample answer: The primary purpose of an ANOVA table is to serve as a standardized format to organize and report both the intermediate steps and the final results of an analysis of variance. A standard ANOVA table typically displays the following six components: the sources of variation (between groups and within groups), the sum of squares (), the degrees of freedom (), the mean squares (), the calculated statistic, and the associated -value.
Key points:
- Defines the purpose as organizing and reporting intermediate calculations and final results of an analysis of variance.
- Lists sources of variation (between groups and within groups) as a standard component.
- Lists sum of squares () and degrees of freedom () as standard components.
- Lists mean squares () as a standard component.
- Lists the calculated statistic and associated -value as standard components.
Rubric: To receive full credit, the student must: 1) State that the ANOVA table's purpose is to organize and report intermediate steps and final results of an analysis of variance. 2) List all six standard components: sources of variation (between/within groups), sum of squares (), degrees of freedom (), mean squares (), the calculated statistic, and the associated -value.

What is the primary function of a standard ANOVA table?
To properly report results in an ANOVA table, specific values must be calculated in a logical progression. Arrange the following steps in the correct order, starting from the initial partitioning of variance and ending with the determination of statistical significance.
A psychology researcher conducts a one-way ANOVA to compare the effect of four different sleep durations (4, 6, 8, and 10 hours) on reaction time using a total sample of 44 participants (11 per group). The analysis results in a Between-groups Sum of Squares () of 60 and a Within-groups Sum of Squares () of 200. Match each ANOVA table component to its correct calculated value.
A researcher presents an ANOVA table for a study comparing three treatment groups with a total sample of participants. The table displays a Between-groups Sum of Squares () of with , a Within-groups Sum of Squares () of with , and a calculated statistic of . This ANOVA table is internally consistent and mathematically correct.
In a standard ANOVA table, which statistic is calculated by finding the ratio of the between-groups mean square () to the within-groups mean square ()?
In a standard ANOVA table, the total variability of a study is partitioned into specific components. Match each source of variation with the type of differences it represents.
In a standard ANOVA table, the 'Between-groups' source of variation is listed with a Sum of Squares () of and a degrees of freedom () of . If the calculated statistic is , the Mean Square Within-groups () must be _____.
A researcher conducts a one-way ANOVA comparing three caffeine conditions (no caffeine, low caffeine, high caffeine) using a total of 30 participants (10 per group). According to standard ANOVA table structure, the correct degrees of freedom for the within-groups source of variation is 27.

Explain how the researchers should structure their ANOVA table to clearly partition the sources of variation, and describe how each column contributes to the final statistical decision.
A researcher is finalizing an ANOVA table for a study comparing three groups with a total of 21 participants. The table lists a between-groups sum of squares () of 40 and a within-groups sum of squares () of 90. Given that the degrees of freedom are and , show the calculations to find the mean squares () and the calculated statistic to complete these empty sections of the table.
