You sir just explained to me in HALF AN HOUR what many other failed ! HA! this is BRILLIANT!! Absolutely in love how you explain things and make them EASILY UNDERTSOOD (coming from a student who's watching this at midnight cuz I'm desperately trying to save my skin)

Really nice video and informative. I would like to know about the post hoct test in Two Way Anova. Should we compare the data between two group or within group ?

Hi David Question: How to create a difference (significance) between groups with the letters a, b, c, or ab, bc,... with the two-way ANOVA test in SPSS?

[@mathslearningUofA]

Sorry I don't know how to make SPSS do things.

what if the interaction shows significant? do we do post hoc for different types of treatment used? for this video 2: dry and wet

[@mathslearningUofA]

The Tukey HSD is the post-hoc test either way.

@@mathslearningUofAYour video is Awesome. For my project, I was comparing different milks at different concentrations and in ANOVA I got F>Fcritcal in interaction. Therefore, do I need to do the Tukey HSD as I am rejecting the null hypothesis. I thought it would be a bit tough, so. Thanks

@@madhavsunar6398 You’re always supposed to do a post-hoc test. The only time you don’t need to is if everything is not significant when you do the ANOVA. If anything is significant when you do the ANOVA, you’re supposed to do the post-hoc test. Note I suggest you talk to a professional about this, rather than someone who made a KZbin video!
