Oh Dear Lord.

Thank you so much!

And what statistical tests should I know?

ahhh thanks man never knew we need to know this :frown:

do we only need to focus on mann-whitney u-test, chi-squared test, and t-test??? what about spearman's rank correlation, for example it came in question 3 of the sample paper do we just mention it or give details
