Determine Sample Size for research activity

(1/1)

imranmahmud:
If approach is PLS- SEM: This  rule  of  thumb  is  equivalent  to  saying  that  the  minimum sample  size  should  be  10 times  the  maximum number  of arrowheads pointing  at  a  latent  variable  anywhere  in  the  PLS  path  model.

else If approach is CB-SEM: A general rule of thumb is that the minimum sample size should be no less than 200 (preferably no less than 400especially when observed variables are not multivariate normally distributed) or 5–20 times the number of parameters to
be estimated.

Else
