Analyzing Dislikeability & Group Effects on Score via SPSS UNIANOVA

This document presents an SPSS UNIANOVA analysis examining the effects of dislikeability and group membership on perceived dislike and score. The analysis includes tests of between-subjects effects, post hoc tests (Bonferroni), descriptive statistics, Levene's test for equality of variances, and estimated marginal means. The perceived dislike was analyzed based on dislikeability and group, revealing significant effects of dislikeability. Further analysis explores the impact of dislikeability and group on a score variable, with significant interaction effects observed. Post-hoc tests and pairwise comparisons provide detailed insights into group differences across dislikeability levels. A bar graph visually represents the mean level of punishment as a function of dislikeability and group membership. This solved assignment is available on Desklib, where students can find a wealth of study resources including past papers and assignments.
