mean and standard deviation of formative measurements

Post by Oemsi123 »

Hello,

I am wondering if it is okay to indicate mean and standard deviation of a formative construct.
I guess it is not really reasonable since the indicators of the formative construct do not correlate highly.
What would you say? Is it still okay to give this information or is it better to only indicate mean values of the individual items?
So far I only indicate the weights, p values, M and SD of the single items and the VIF values.

Thank you for your help!

It could also make sense to look at the mean and standard deviation of latent variables (both reflective and formative). However, you will only get those information from the IPMA. The normal PLS standardized all variables including latent variables and indicators. Therefore, the latent variables (both reflective and formative) will have zero mean and variance of 1.
