Hello everyone I am an undergraduate psychology student and I'm facing lots of troubles with the statistic analysis.
Firstly, I've got 1 independent variable and 7 depended ones and my data is not normally distributed.
My main problem is that I don't know when and why to use a specific statistic test.
For example, I run a Kendall's tau for correlations. Most of my dependent-independent correlations are not significant (NS).
So, my first question is if I should run a linear regression analysis (is there a non parametric equivallent?) for NS correlations? Keep in mind that my grouping variables are not equal in size.
