A matched-pairs \(t\)-test is NOT an appropriate way to analyze data consisting of which of the following?
Approach
A matched-pairs \(t\)-test is appropriate when data from two groups are compared before and after or when a singular group is given two tests at different times.
In the answer choices, we also see some matched pairs comparing appropriate pairs of data (twins, individuals with similar education).
If pairs are formed randomly, there is no real reason to use a matched-pairs \(t\)-test.
