Running a Mixed Model in R with lmer

In this final video of the series, I demonstrate running a simple mixed model in R with the function lmer.

This video is a step-by-step demonstration of how to run a mixed model in R with lmer, using the sleepstudy dataset.

Find the script and the slides at these links. Also, here is an additional script to practice this method on the stroop dataset.

Here is the introductory talk of this series, and a demonstration of this mixed model in SPSS (achieving the same output) by my colleague Mary Agyapong.

I also provided an essential tutorial to read the output of lmer when fitting this mixed model in R.

Hope you enjoyed this series, and you will enjoy even more fitting mixed models on your data in R (and SPSS, if that fits you better).
