cheers thank u anyway

please help me I dont understand!!!

I do use SPSS, part correlation is the same as semi-partial correlation. The question is just on the theoretical concept, not an actual calculation using SPSS. The question says which of the following are true? 1) in a multiple regression with statistically significant predictors, the part correlation for any predictor will always be greater in value than the partial correlation. 2) in a multiple regression with statistically significant predictors, the part correlation for any predictor will always be lesser in value than the partial correlation. 3) in a multiple regression with statistically significant predictors, the part correlation for any predictor will be greater in value than the partial correlation if the predictors do not share variance. 4) in a multiple regression with statistically significant predictors, the part correlation for any predictor will always be greater in value than the zero order correlation correlation. 5) none of the above.

sorry i didnt know! thanx for the advice

In a multiple regression with statistically significant predictors, the part correlation for any predictor will always be greater or lesser in value than the partial correlation??? Or is it just that it will be higher/lower than the partial correlation if the predictors do not share variance??

if anyone has any clues on this other question that has been puzzling me any help would be greatly appreciated! * someone who runs a correlational analysis says that an effect size of 64% has been found. What value of Pearson's r did they obtain? 1) +0.8 2) -0.8 3) 0.8, we cannot tell whether the value is positive or negative 4) +0.64 5) none of the above

thanx guys if anyone has any clues on the other question that has been puzzling me any help would be greatly appreciated! * someone who runs a correlational analysis says that an effect size of 64% has been found.

is it possible to calculate effect size if u hav pearson's r value?

thanx i thought it would be either zero or none of the above but i guess i didn't really understand the question (or the theory behind it)

Hey I need sum help wif a Research Methods assignment. The question is if two variables are totally independent, then the correlation between them is: 1) -.01 2) -1 3) +1 4) zero 5) none of the above Any help would be great Im very stressed!!!
