paired sample. one sample t test is if you want to compare a group mean to a specific mean (e.g., see if the mean of a variable is significantly different from 100).Midna wrote: First: I'm not sure if I should use a one-sample t-test (I think so ...) or a paired t-test seeing as the data comes from the same person.
I really wonder what you have done with the one sample t-test, because it does not seem possible to do this with your design. What have you clicked on?? Maybe you compared both variables means with 0 by accident.Second: I have done the one-sample and the paired one and both show ,000 sign for all my data. Which to me seems very strange.
people tend to use likert scales in these types of situations, but indeed it is not correct. if it is ordinal, use Wilcoxon signed ranks test.As some of the data (Agreeableness) only has 0,3 difference in mean if you compare the social against the personal situation (if you put it in a graph the means are nearly identical). I'm thinking it's maybe because of my data. It's a 7 point scale (from "very like me" to "totally not like me") because as I understand data should be continuos for this test (and mine is not). But my professor told me to use a t-test, so not sure what I should do ... Normally we get a whole course about this but I was allowed to do a shorter program because of a pervious degree, but now I'm having a lot of trouble with SPSS since I've never used it before until a few months ago .
