SPSS Syntax and Output for Univariate and 2-Way ANOVA

This article provides SPSS syntax and output for conducting Univariate and 2-Way ANOVA on datasets related to punishment and dislikeability. The article includes graphs, tables, and statistical tests for analyzing the data. The datasets used in the analysis are from Griffith and UQ universities. The article also provides information on post-hoc tests and estimated marginal means.
