Hi

**lonestartiger**
First, no need to be embarrassed, asking questions is the goal of the forum ..,

Is it daily treatment? every day before and after the treatment?

Or is it one-time treatment?

Can you please be more specific, what are the minutes and what is the score?

What test do you plan to use?

Generally, I think that both calculations are correct, really depend on what you want to check ...

General

**group **measurement of the group would be calculated as (16+5+4)/(2 + 1 + 1) ).

in this case, you don't treat each person as one equal observation, but the group

But if you want to treat each person as

**one observation **(equal) then you should do average per person's results (8+5+4)/3
