1/15뒤로Skip to main content뒤로One-Way ANOVA
A statistical method for comparing means across three or more groups using a single test to detect significant differences. Null Hypothesis
The initial assumption that all group means are equal in the context of comparing multiple groups. Alternative Hypothesis
The statement that at least one group mean differs from the others in a multi-group comparison. F-Statistic
A value calculated as the ratio of mean square between groups to mean square within groups, used to assess group differences. P-Value
A probability measure indicating the likelihood of observing the data if the null hypothesis is true; compared to alpha for decisions. Alpha Level
A threshold probability, often set at 0.05, used to determine statistical significance in hypothesis testing. Mean Square Between Groups
A measure of variance reflecting how much group means differ from the overall mean. Mean Square Within Groups
A measure of variance showing how much individual values differ within each group. Data Analysis Toolpak
An Excel add-in providing tools for statistical analysis, including options for running ANOVA tests. Source of Variation
A component in ANOVA output identifying whether variance arises from differences between groups or within groups. Experimental Design
A structured approach for assigning participants to groups and collecting data to test hypotheses. Group Mean
The average value calculated for each group in a dataset, used for comparison in ANOVA. Hypothesis Test
A formal procedure for deciding if observed data provide enough evidence to reject an initial assumption. Variance Between Groups
The extent to which group averages differ from each other, indicating potential differences among groups. Variance Within Groups
The spread of data points inside each group, reflecting consistency or variability among group members.
