SPSS analysis method urgent

Hi all,

I got raw data from a group of students sample, sample size 100, 3 independent variables, 1 dependent variables.

Between multiple regression, one way anova, two way anova, and ancova, which one should i use to analyse?

and how to analyse them?

Could you please draft a procedure on which test should i use and how to test for my data?

Thank you very much.

Best regards,

a poor girl trying to analyse my raw data

One should define the null hypothesis and the statistical test(s) to be used before the experiment is run is the more kosher route.

Perhaps post the data. Also, provide more details on the independent variables and the dependent variables.
