Suppose I have a percentage for each subject of two groups. I would
like to compare means of percentages of two groups. How to do sample
size and power calculation? Suppose I don't know how and where those
percentages come from.
No 2 by 2 table please, no two proportions comparison please.
Can I treat average percentage as average age when I compare two
means
of percentages?
Many thanks in advance. |
