These materials walk through the basics of MLMs: why/whether you need one, fixed and random effects, specifying models, estimation options, effect sizes, troubleshooting errors. We start from linear regression and take you to running your own MLMs. (3/6)

There are examples with built-in code and output in every chapter. You can download code, data files, and worksheets to follow along at home, or just to use as a jumping off point for your own analyses. (4/6)

If you're an instructor creating an MLM course at your institution, feel free to take the code, data, worksheets, etc. for your own course prep!
