You could perform Kruskal-Wallis on these data. However, the Kruskal-Wallis procedure would convert the raw (continuous) scores into ranks, and the K-W procedure would test the null hypothesis of equal mean ranks across groups. Most people are not interested in testing the differences between the mean ranks across groups, so, they conduct the one-way between groups ANOVA, when the assumptions are satisfied.
Hi the lesson is very clear and informative. Is there a followup lesson?
Hello, could you tell me what could be the reason my "teacher group" variable is not showing up when i try to run anova?
Change it to numerical
Dude, you seriously could cut out the first 2 minutes
Why can't we perform kruskal Wallis in this data?

You didn't really talk about how to interpret the results...
+Dinnah Didulo this is only part 1 of 5
For future reference.. You talk way to much.. Get to the point. But otherwise this is appreciated greatly!
