Is mixed ANOVA the same as repeated measures ANOVA?

Is mixed ANOVA the same as repeated measures ANOVA?

However, the fundamental difference is that a two-way repeated measures ANOVA has two “within-subjects” factors, whereas a mixed ANOVA has only one “within-subjects” factor because the other factor is a “between-subjects” factor.

What is a repeated measures mixed ANOVA?

While a ‘repeated-measures ANOVA’ contains only within participants variables (where participants take part in all conditions) and an ‘independent ANOVA’ uses only between participants variables (where participants only take part in one condition), ‘Mixed ANOVA’ contains BOTH variable types. In this case, one of each.

Why use linear mixed models instead of repeated measures ANOVA?

From what I’ve read linear mixed models are usually more accurate and flexbile than repeated measures ANOVA. So, using the lme4 package in R to perform a linear mixed model, my dependet variable would be heart rate, the fixed effect would be the condition and the random effect would be the high and low group, right?

When to use repeated measures in mixed model?

As implied above, mixed models do a much better job of handling missing data. Repeated measures ANOVA can only use listwise deletion, which can cause bias and reduce power substantially. So use repeated measures only when missing data is minimal.

Can a repeated measures ANOVA be performed with SAS proc mixed?

SAS proc mixed is a very powerful procedure for a wide variety of statistical analyses, including repeated measures analysis of variance. We will illustrate how you can perform a repeated measures ANOVA using a standard type of analysis using proc glm and then show how you can perform the same analysis using proc mixed.

When does repeated measures ANOVA start to fall apart?

Repeated measures ANOVA falls apart when repeats are unbalanced. For example, a common design is to observe behaviors of different types, then compare them. One of the data sets we use in our Repeated Measures workshop compares the time it takes an infant to breath out while uttering different types of sounds.
