32 (out) of 33 samples... - (Dec/27/2012 )

Hi!

Can someone tell me which is the correct form to explain that I have 33 samples and 32 of them are positive?:

- 32 of 33 samples were positive.
- 32 out of 33 samples were positive.

This is something that I always discuss with my PI

Thank you!!

32 out of 33 samples were positive

or 96.97 % (rounded)

Thanks! (I was right!)

Actually, either can be used, though it would be more common for the first one to have the form "32 of the 33 samples were positive".
