Significance Level


New Member
Hi there,
I have to perform a hypothesis test at the alpha = 0.02 significance level to compare two means. In SPSS, I have chosen Analyze/Compare Means/Independent sample t-test, but how do i enter the 0.02 significance level? I hope you can follow what i'm trying to ask?

Any help would be appreciated,

You don't enter the significance level anywhere - the t-test will give you the probability of the results, if Ho is true, and you compare this probability to your significance level.
