Comparing the strength of relationships

Post by ngn999 » Wed Apr 10, 2019 9:45 am

Hello everyone,

I have a model in which 2 IVs (A and B) ---> DV (C), running SmartPLS. A, B, and C are reflective constructs measured by 7-point Likert items. It is hypothesised that the positive effect of A->C is stronger than the positive effect of B->C. Is it enough if I use path coefficients and effect sizes to compare the effects of A and B on C and then support this hypothesis or I need other analyses?

Thanks in advance.

Of course a descriptive analysis of the path coefficients provides a first indication, but it would be better to really test if they are different.
