Normality test
Posted: Tue Feb 21, 2023 3:10 pm
Hello everyone!
I am following a course, the first of my life, in statistics
with jamovi 
Anyway, I was given an exercise, to test the normality of 3 variables (2 continuous such as IQ, and the score of a test; 1 categorical such as the economic status expressed numerically) with Shapiro-Wilx.
But each variable count 2287 observations, and I guess it's an error to use S-W due to the large size. Anyway, the p for S-W was <.05
Then I wanted to perform the Kolmogorov-Smirnov test and to do it I used this path:
T-TEST>One Sample t-test, I selected the 3 variables, than Assumption Checks>Normality test.
The results of K-S were p<.05
Have I done it correctly?
Thanks
