I really hope someone can help me as i have been reading about this stuff and i am still really confused!
I have a dataset of 180 chemical compounds with 2 data (numerical) values each - i want to see if there is a difference between these two data points for each of the compounds for the whole dataset however my data is not normally distributed so my questions are:
Am i ok to use a matched paired wilcoxon rank test? Or can i get away with using a normal paired t test?
I have had been reading alot online an i just want some checking i am understanding! Any additional help/resources will be appreciated! Thanks in advance :)
