You are a good teacher💯🙌♥️👏thanks a lot.

Brief and smart explanation sir just like u explained us in our class (Y)

Nicely explained. Could you please suggest on how to get the minimum sample for pilot test? Kindly suggest.

Regarding observed variables: Should they be the items of the scale in any case? For instance, I have a very generic latent variable like "life events" and I want to observe it through some dimensions like "accidents" and the other one is "unexpected health problems". Lets say "accidents" has dimensions "air plane accidents", "traffic accidents", ""sports-related injuries" etc. and it has 86 items. Can I keep them as IVs to assess "life events"? Because otherwise I would have lets say 350 items in hand to assess life events. And I cannot collect such a huge data (I mean the sample size).

Hi, does an interaction term of two latent variables count as another latent variable when calculating sample size? I have two predictor latent variables and one outcome latent variable (3 latent variables altogether).

However, I am also going to examine the interaction of the two predictors on the outcome as well. Does this count as another additional latent variable for my model? Or does it remain just 3 latent variables? Thank you.

Thank you so much for your simple and brief explanation. Can you give an elaborate description about SEM model? How can I select the number of latent and observed variable for my study? I am really interested to do run SEM model for my research but I am facing difficulties to understand this. I have already watched a Couple of videos but your explanation is easy to understand for me. Please can you help me in this regard.

how to use it if the constructs are second-order? for example, a 5 latent variable model, the latent variables have two secon-order latent variable, for each second-order construct have 5 observed variables (items), so do i need to put 10 in the latent variable and 50 in the obsered variables? thank you

I see from your tabs that you're also using GPower. Does GPower also show the same results?
