Lecture 5: More 2x2 Factorial Design

3x2 ANOVA

6 conditions, one IV has 3 levels and the other IV has 2 levels

Mixed ANOVA

One between-subjects and one within-subjects

On SPSS for repeated measures

We have a column for each measure

2x2 Independent Groups Design

both factors are between subjects e.g. experience and age

2x2 Repeated Measures Design

both factors are within-subjects e.g. target type and timing of assessment

To make interpreting results easier

break down into three 2x2 interactions, if one is significant then the interaction is significant

When using more than 2 levels

need to look at Mauchly's test of sphericity and Levene's test

Parallel lines probably indicate

no interaction

Assumptions made when 3x2

the same as 2x2
