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.

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

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)
