    HELP! T-test, normality assumption. Great difference between Shapiro Wilk and Q-Qplot/ Z-score calculation

    You're right about this. The thing is I need to write down the interpretation of the assumptions I've tested prior to my T-test. That's why I want to know whether I should interpret the normality output of the Shapiro Wilk or of the Q-Q plots/ Z-score calculations

    Hey there! I have a question about the difference in results between the Shapiro Wilk test and the calculation of a Z score with skweness and kurtosis (divided by SE). I have a sample size of N = 143. It is divided into two groups (Western candidates N = 71 and non-Western candidates N = 72)...

    Testing covariables ( doing an(c)ova with multiple independent variables?)? in SPSS

    Yes, that's true, but which results do I report in my "results section". Do I report the F-value and significance of educational level only if I want to answer my question? Or do I report more? (like also the interaction ?) And as you can see the values are different, depending if I put all...

    Testing covariables ( doing an(c)ova with multiple independent variables?)? in SPSS

    Hi, Thanks for your reply! I have 16 groups which can be divided into four groups: e.g.: both primes, ethnic prime only, personal objectivity prime only, control groups (no prime at all). (See attachment). Within these groups participants either got a western candidate (variable candidate...

    How to create 1 (continuous) variable by using two (continuous) variables (and ignore the missing) in SPSS?

    Thanks I fixed it ! :) I did the following: compute appl_credent = Wes_appl_credent . if sysmis(Wes_appl_credent) appl_credent = NonWes_appl_credent . execute.
