Seriously. The best two-way repeated measure tutorial on the planet earth. Thank you!

You are a saviour sir. From last two days I was stuck with chat gpt and bird in inderstanding this. Your 20 minutes explanation solved it all.

Thank you does not cut it in explaining how grateful I am to you for this video. You have solved a month-old challenge for me. You provided all the answers in clear, simple and straightforward words. I could use it directly to interpret the data I am currently working on. I will definitely share it with my circle.

Your explanation helped me to further explore my data for my doctoral dissertation from a different perspective. Especially the programming part at the end of comparing time and treatment groups. A simple "Thank You" feels inadequate as this little nugget of a video was a tremendous help! A heartfelt appreciation, for you Dr. Crowson!

Such a useful video it was! This video just made me relieved of confusion. There is only one question left for me. If there were two dependent variables (like Anxiety and maladaptive schemas), should I do two-way repeated measures for each one separately?

[matheushausen]

Thanks a lot! Great explanation. Please, could you provide any reference for rules of thumb?

[thanhchaunhut]

thank you for your videos Sir. Very helpful!!

[alinewoine]

Thank you for your wonderful video. Regarding the Levene test - I hope I understood you correctly - is it acceptable to "ignore" a positive test regarding one or two measurement points if the groups are equivalent (n largest / n smallest < 1.5) ? Do you have a source of literature on this topic?

Hello, thank you, in the comparison of 3 times; What should be done if the number of people at the 3rd time is less than the first 2 times? Pretest and posttest were taken from the control (n=17) and experimental (n=17) groups, but the follow-up measurement was taken only from the experimental group and could only be taken from 13 people. Which tests do you recommend?

[yuqiguo]

This is so useful and everything is just so clear! Thank you so much!!!

Hi Sir, Thanks a lot. This video made my day!

[minahabibi]

thank you so much you explain everything in detail. do you have any example or power point about the situation if we have one between factor and two within factor in repeated measure to share please

Hi @Mike Crowson! Thanks so much for this massively helpful tutorial video. I was wondering if you might have a sample corresponding write-up that you would be willing to add to the end of the slides or share elsewhere. This video has helped to walk me through my own data a great deal, but I'm struggling to figure out whether to discuss the overall model and then how to situate that vis-a-vis any presentation of the tests of within-subjects effects and tests of within-subjects contrasts etc. I've got Warner's Applied Statistics manual but find myself getting a bit confused as I move across multiple sources and I thus wonder if comparing your write up of this data to the video presentation of the analysis might allow me to see where I've run myself into confusion about what each of these bits are telling me with my data. Thank you in advance for your time and consideration (as a fellow academic I can understand what it is like to teach your classes and to also feel like you are running an additional course with internet students).

[Libra_Focus]

Thank you. The explanation is very clear. Can you give an example on reporting the results of the two-way repeated measures ANOVA and how to arrange the tables (or what tables to be included?) in the results and disucussion section of the thesis?

[errianejustineenverga]

Good day, Dr. Mike! In your example, the interaction is significant How about if it has no significant effect? Thank you!

I’ve just cried happy tears watching this. So god damn stressful
