I have been cracking my head for 2 weeks but i havent been able to figure out this, so i decided to ask for help.
I have done a regression between my independent and independent variable and found nothing.
Now my supervisor wants me to find out if what i wanted to find, can only be found at the extremes.
So participants with the lowest scores (10% left) and participants with the highest scores (10% right).
My supervisor didnt give me much help, she only said something about using ANOVA?
I hope someone can help me.
