This tutorial is going to take the theory learned in our Two-Way ANOVA tutorial and walk through how to apply it using SPSS. We will use the Moore dataset which can be downloaded using this link.

The data is from an experimental study which consists of subjects in a “social-psychological experiment who were faced with manipulated disagreement from a partner of either of low or high status. The subjects could either conform to the partner’s judgment or stick with their own judgment.” (John Fox, Sanford Weisberg and Brad Price (2018). carData: Companion to Applied Regression Data Sets. R package version 3.0-2. https://CRAN.R-project.org/package=carData).

• Low
• Medium
• High

Our sample size is $$N = 45$$. First, let’s inspect the data for outliers or funky distributions by creating a boxplot of conformity scores within each combination of partner.status and fcategory. To create the boxplot in SPSS, go to Graphs $$\rightarrow$$ Chart Builder…
