Dear friends, I have a doubt about this exercise. When doing a germination test using two treatments a student had this results: Treament 1 = 30 seeds germinated (52%) ... and ... Treatment 2 = 50 seeds germinated (25%). The problem is that the sample size was not the same; in one treatment he was using more than 60 seeds and in the other one only 50 seeds !
What kind of test he can use ? Chi-square ? A proportion test ? Is there a test to compare percentages ? Thanks for any help ? Voltolini ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Prof. J. C.
