I'd just like to say - thank you so much for posting these videos. I was a student of yours a few years ago, and really loved your classes. Unfortunately, I did not keep my mind sharp and practice stats for the most part of my post-grad... Now that I need them again, these videos are a life saver!
How can I analyse 3 groups of rats all given before treatment and after treatment oral glucose tolerance tests? Each test has 4 results (0mins 30mins 60mins 120mins). So for every rat I have 8 results (before and after treatment). ATM I have done repeated measures using 1 with-in subjects factor that has 4 levels and I added two measure names (before and after). Am I on the right track here? If so what is this called? Would very much appreciate some help. Thank you!
Hi, I'm working on a 2x3 mixed ANOVA. I'm wondering how to find the direction of effect, or exactly where the effect is happening? Do I use a post hoc test? Or can I do this by conducting multiple paired samples t tests? thanks!
Hi, amazing help, is there a way of implementing different covariates on the different repeated measures for example adding temperature of time 1 to time 1 only and temperature of time 2 to time 2 only? at the moment I am only able to add an overall covariate to both repeats, not separate them which may not be accurate.
Hi, I have designed a testing situation where all students are exposed to treated completion questions and untreated. Treated means underscoring and highlighting certain key words or phrases, which is meant to increase student focus and possibly produce better results on average. I am using 1 for correct and 0 or incorrect, as completion question answers are basically either correct or incorrect. This is action research meant to start an investigation into learner-centered testing strategies. After designing 30 completion questions, I randomly selected 15 for my experimental and control questions. My sample of 21 students took 2 different exams (in the same course) with the same 'experimental' design. I want to see if students, on average, did better on the treated questions compared to the untreated questions in both exams. I also want to see if students did better on the second exam on treated questions compared to the first exam, with reference to performance on control questions. How do I analyze these two questions? Thank you very much for your time. AS

Thank you so much!!! You saved my life and my bachelor degree!!
And now my master degree as well! :)
Man!.. I owe you a dinner!!!..thanks a lot, it helped me in my assignment!!
Thank you so much for these interesting videos! Love watching them and learning SPSS before bed :)
Outstanding, brilliantly simple very very nicely explained, I was able to do a 6x6 mixed measure anova thank you so much
Thank you so much! I am using this video as a guide for my assignment
Thanks for all the videos, helped me alot with learning for spss practica!
Thanks for this video. It was incredibly helpful.
Hi, have you got a vidoe that goes through writing up the mixed design anova?
Thanks so much!!! It worked
LIFESAVING VIDEO!
I have a similar experiment but I have 3 replicates - how do I analyse this?

Is this about multilevel modeling? the last version of SPSS seems quite nice for that. Have you prepared a video on that?
Hi,
I'm working on a 2x3 mixed ANOVA. I'm wondering how to find the direction of effect, or exactly where the effect is happening? Do I use a post hoc test? Or can I do this by conducting multiple paired samples t tests? thanks!
Thanks, this is great! Will this also work for a 3 x 2 Mixed (between x within) design. Are contrasts necessary?
can u please tell me which post hoc test can be used after a split-plot ANOVA? Thanks

What if theres more than one variable being measured (before and after) what analysis would i use then?
I wonder if there is a non-parametric equivalent to the split-plot ANOVA
If you find, would you let me know please??
+Joe Varghese In SPSS, no. However, there are suggestions and/or alternative methods to do the analysis.

Can you use this method with a crossover design?
thanx for the video
Becasue I DID NOT USED split-plot correctly,my paper was rejected by SOIL BIOLOGY AND BIOCHEMISTRY.
what is the test to be used if I study pre/post test in single group?
If I understand you correctly, a paired samples t-test: ruclips.net/video/sym7pddXzzI/видео.html
