Yes, your are right! The video is part of my playlist on measurement invariance: th-cam.com/play/PL-kVjeOVYChrkO8lMrRsHZuYxvYY6KW35.html Best, Christian Geiser
Great video! Can we test measurement equivalence with more than 2 groups (at the same time) e.g. younger vs. middle-aged vs. older adults? I am asking because so far I have only seen examples with 2 groups.
Excellent! I am wondering if there is a technique to test measurement equivalence across continuous variables such as age (e.g., ranging from 20 to 80 years old) or if we must create 2 or more groups even with variables that are continuous. @@QuantFish
@@will74lsn Great question. Continuous variables are somewhat tricky. Age groups (e.g., 20-30, 31-40, 41-50 etc.) would work for the sake of invariance testing to at least screen for non-invariance in different age ranges. (It is likely not necessary to look at every single age separately.) Best, Christian Geiser
@@will74lsn For testing measurement equivalence across levels of a continuous variables, you can also check out the following paper: Bauer, D. J. (2017).

So thankful I stumbled upon your channel. Really appreciate the clarity and intuition you teach with.
I really appreciate your positive comment. I'm glad my content is helpful for you!

Yes, there can be more than 2 groups.
