This video has helped me more than you will ever know. Went from a politics student way out of his depth, to a politics student with an undergrad diss observing a significant statistical difference between political orientation and personality types, which is super exciting (at least for me). this video is the difference between a 2:1 and a first for me so thank you
That is true when you are constructing your hypotheses at the beginning. You are looking for a difference only. Once you have the findings, however, you can note that the outcome was higher (or lower) because you now know the actual direction of change. At the outset, you are looking for change in either direction. Hope that clarifies. Best!
What do you need to do if both Normality and Equality of variances assumptions had been violated please? (my sample is less than 30 and the two groups are not of equal sizes - and I still need to draw some results from it). Many thanks for your help!
With that many violations, any conclusions that you draw from that data are unlikely to be reliable. You can still run a test and interpret it, but you really only know something about your sample, nothing you can extrapolate back to a population. Any conclusions may be right, may be wrong, but you will not know which one. Best option is to collect more data. Good luck
Hi, i have been following your videos for a while but it seems like the majority of them are about very basic hypothesis tests. Would you make videos about more advanced hypothesis tests in the future like two way or three-way paired ANOVA or MONOVA with SPSS?
I started with the basics because, honestly, more people view them. I have some deeper stuff on data handling on the channel, but the good news is that more advanced stats are coming. I am currently working on several scripts including advanced techniques in ANOVA.

You are a genius! This video really helped me.
hey I think you were mistaken at 15:50, since it is a two tailed test you should report saying we expect to find a difference only

To check for equality of variances, my JASP only shows Brown-Forsythe instead of the Levene’s. How do I set it to the Levene’s. Thank you.

Hi, how can you tell there is a significant difference?

@@ResearchByDesign so at the same time if lavines test is significant the variables can be homogeneity?
t= NaN
