What type of t test should be used to determine the difference between baseline and most recent period?
That is, is the reduction a meaningful change?
Can anyone tell me if I calculated the P Value correctly?
I have analyzed two biological sample (Soil 1 and Soil 2) by Mann-Whitney U test using GraphPad Prism 6 software.
I got following result
Table Analyzed One-way ANOVA data
Column B Soil 2
Column A Soil 1
Mann Whitney test
P value < 0.0001
Exact or approximate P value...
