Yes, please send me free statistics resources, news on webinars, workshops, and more!

Mixed modeling is rarely, if ever, covered in even upper-level statistics courses.

Trying to learn it on your own is like prepping to perform your own appendectomy — and just about as painful…

But there IS an easier path to learning mixed models, one that researchers without a Ph.D. in statistics can understand.

In this free, one-hour webinar, Karen will provide a clear explanation for getting past the equations, math, and confusion that come with mixed models as she introduces and demonstrates two of the core concepts of mixed modeling.

Covered in this webinar:


  1. How Random Intercepts control for the correlation among responses from the same individual
  2. How a Random Intercept is not much different from adding a fixed effect to a model
  3. Why a Random Slope doesn’t work in many designs
  4. And more!
