Yes Mary, you do use the values mentioned aboved (original sample).

And thanks again Christian for the reference.

Hey Mary, you don't need to actually "work out" the "a"s and "b"s. As I stated above, a and b are the path coefficients of the original sample. You can find them in your Bootstrap-Report under: Bootstrapping -> Path Coefficients (Mean, STDEV, T-Values) -> The first colu...

Calculating T-Value for indirect effects: a*b/sd(ai*bi) ?

Hello everybody, i am trying to calculate the t-value for an indirect effect in my model. The number of participants in my experiment is quite small (n=104). Therefore, I can't compute the t-value using the Sobel-Test because the results will be biased if "n" is less than 200. As far as I ...
