Join Yash Patel for an in-depth discussion in this video Assumptions and hypotheses, part of SPSS for Academic Research.
- [Instructor] The first assumption…for the paired T-test…is that there must be…one dependent variable that's continuous.…Time is certainly continuous,…so we can go and check that.…The second assumption…is that there must be one independent variable…that consists of two and only two categories…or related groups.…These groups should not be independent.…There should be the same participants in each group…unless you're using the cross design…that I mentioned that reduces biases.…Regardless, the starting participants…should remain the same.…
We have the same participants throughout in our design,…so that really shouldn't be an issue.…Also, we have two categories or related groups,…the carb supplement category…and the protein supplement category.…The third assumption…is that there are no significant outliers…and the differences between the two treatments.…We're going to have to create a variable…that captures a difference…between the two paired observations.…In this case, we'll take a look at box plots…to see if any outliers exist…
