Experiments with a mixture of repeated measures and between subjects factors

I often speak to researchers who need to analyse an experiment with a combination of between subjects and repeated measures factors.

Some Examples:

• 5 x 3 Design: 5 levels of task type (repeated measures); and 3 levels of group (between subjects)
• 2 x 2 x 2 Design: 2 levels of order (between subjects); by 2 levels of instructions (between subjects); by 2 levels of task feature (repeated measures)

This post directs such researchers to some resources on the web.

Resources:

• UCLA has several examples of how examine such designs using SPSS Repeated Measures ANOVA; It also talks about how to test contrasts and run follow up test more generally.
• Andy Field provides a gentle introduction to repeated measures ANOVA using SPSS.
