Hello!

I am new to statistics and I was wondering if you could help me.

I have collected weight and height of 80 people, those have performed a test twice. This mean, I have two final scores for each person (160 scores).

With jamovi I got the IQR of weight and height, and I need to understand if these variables could impact the scores. This mean I have to find evidence against the null hypothesis by percentile (25th, 50th, 75th) comparing the scores by height and weight and BMI.

How do I proceed?

Thanks for your support
