Hi all... I've recently carried out a biological investigation in which I was comparing the abundance of winkles on "three" different algal species. I have three sets of data for each species each containing 15 results. So a total of 45 readings. My hypothesis is that the winkles are equally distributed on all three wrack species i.e. 33.3% on each.
I was trying to verify my results and see if this is true. I am not sure if Chi Squared test works with three sets of data. Is it possible? Moreover, I thought of using Mann-Whitney or T-test and consider the investigation's hypothesis as the test's null hypothesis and hope the value is less than the critical... I think this last bit is sooo unreliable, particularly that it means to compare each two results together... I would appreciate any help even if it involves a statistical test that I have mentioned above. I am really desperate ;) Thank you in advance, CK out. . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
