I like that Dr. Grande is making videos that deal just with the statistics themselves, focus on these concepts outside of their use in statistical software.
I found this video to be helpful to determine when to use a two-way mixed ANOVA compared to when you use a two-way repeated measures ANOVA, this helped to clarify what the differences are between the two.
This video was helpful for me to understand this concept. I like how Dr. Grande reviews interval and ratio levels in each of these videos as well. It helps me to remember the concepts.
I found this video to be very helpful and easy to follow and understand, especially for when designing a study that requires the use of a two-way mixed repeated measures ANOVA
I agree, my research proposal requires a SPANOVA and I was having difficulty understanding this test and how to conduct it/describe it until this video. Overall, very helpful for replication. His Split-Plot ANOVA SPSS video is a good addition to this video if you are interested more in this test.
If a participants are split into two groups to test a new drug (group 1: new drug / group 2: placebo) and they all complete questionnaire before taking the drug and an hour later, would this be a mixed-design ANOVA? Or does it need at least two post-tests and not just one?
Thank you for this video, subscribed! I have one question. I used a few control variables in my data-collection and am now wondering which ones to consider in my ANOVA. I assume you look at the correlations between the control variables and your outcome measure. Is there a certain cut-off? (for example considering those with a correlation of over .70 with the DV)?
Hello, when i test Homogeneity of Variances in Split-Plot design, am i supposed to test it for all levels and combinations? like in normality? or just the subject factor?
Thank you for the video. In SPSS, what does a non significant interaction mean? (but means effects are significant). I can not reject the null hypotesis? Thank you for your answer!
A non-statistically significant result for the interaction would mean there is no interaction effect. There can be significant main effects, but still be a non-significant interaction effect.

Thank you for the comprehensive video, repeated measures ANOVA is useful statistical method in many majors.
You're welcome, thanks for watching -

Super helpful thank you so much.
Would you post a video about how to check each of the assumptions?

May I ask what is the minimum sample size for a two-way mixed ANOVA?

How if our data is not normally distributed?
