Im currently doing my biology coursework and i am confused as to what statistical test i should use to analyse my results.

I am testing the effect of different hand wash on clearing bacteria, and my results are as follows:

SOAP USED -- AVERAGE AMOUNT OF BACTERIA CLEARED
SOAP 1 -- 1.6CM^2
SOAP 2 -- 0.7CM^2

Am i right in thinking i could use the mann-whitney test?

Thankyou
