I have 10 participants who consumed an intervention for 3 weeks. I would like to look at any significance between pre-intervention and post-intervention readings. What SPSS test should I use?
I have tried doing a Paired samples t-test because it's the same sample at 2 different times but got confused on which data to place in variable boxes.
This is because I have 4 sets of data: mean systolic before, mean systolic after, mean diastolic before, mean diastolic after for each of the 10 participants.
If Paired T-test is correct, would it make sense to do this:
Pair 1: Variable 1 (systolic before) -- Variable 2 (systolic after)
Pair 2: Varible 1 (diastolic before) -- Variable 2 (diastolic after)
