1) If I have five psychological test battery scores (would that be independent variables) and want to see which of the five tests would predict higher academic grades (would that be dependent variable)...would I use multiple regression analysis? and should i also do predictive validity (i.e. correlation)
2) There is only 100 participants in the study...would I use raw scores over stanine scores (no demographic info in the data set i.e. gender, age)
3) what does it mean to show the distribution of scores (i.e. would i show a gragh with a normal distribution curve)
Thaks in advance
