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 ?
