Question in regards to Tukey's Multiple Comparisons Test
Nov 22, 2017 3:09 AM(8876 views)
Would anyone be able to tell me how to go about running a Tukey's multiple comparisons test on my data? I've collected soils samples from 3 farming systems (n=3) on day 0, 14, and 28. I'm measured the cfu. I'm trying determine whether or not there's a signifacant difference between the 3 farming systems on each collection date. I know there's no sig. dif. on day zero and I'm pretty sure there's a sig. dif. between the farming systems on day 14 and 28, I'm just not sure how to go about running the stat. analysis to prove that. I've inserted a photo of a graph and my data. Any help will be greatly appreciated!
