Yes. You may use it for analysis. You have to check the assumptions of each statistical analysis. If normality is an assumption, then go for non-parametric tests.
Based on the context. if the Dichotomy is based on the total score (dividing to two categories), it has to be biserial correlation. Sorry for the confusion.
Well taught yes BUT are you writing on glass?? That means you're writing in mirror language in real time with any issue! This is soo cool I've never seen this in educational videos or anywhere actually, but also kinda distracting cus i was so baffled that couldn't focus on the topic😅 Or you just flipped the foootage nv lol

Thank you so much for helping us. Please help me how to draw ROC curve.

Hello Sir , I just got confused at the end... scale construction uses biserial or point biserial ?
Based on the context. if the Dichotomy is based on the total score (dividing to two categories), it has to be biserial correlation.
Sorry for the confusion.
Point biserial is a non parametric test, but then why it's assumption s normality. Can I use it n non normal data
point biserial is a parametric test
I want to calculculate effect size for Mann-whitney test, is this suitable to it please? Thank you!
Z/root(n) is the meaure we generally use for it. I shall try to get some reference too. Sorry for the delay.
@@dr.justinesclassroom7979 no prob bro... It's ok
Its really helpful
Glad to hear that
Well
