SPSS : One Way ANOVA and Posthoc Analysis

The One-Way ANOVA test in SPSS is used to compare the means of three or more independent groups to identify significant differences. If a difference is found, post hoc analysis (such as Tukey’s test) helps determine which specific groups differ. This test is widely used in experimental research to analyze group variations. SPSS provides a straightforward approach to performing ANOVA, checking assumptions, and interpreting results. Mastering this test allows researchers to analyze multiple group comparisons efficiently.
