In a study investigating the second stage of filter theory (similarity of attitudes), a student researcher recruited a sample of participants to evaluate potential dating profiles.
The student researcher decided herself, based on her own judgement, which attitudes should be classified as 'similar' and which should be classified as 'different'.
Participants were asked to rate their desire to date the person in each profile on a scale of 1–10. The researcher planned to use a related t-test to check for a significant difference between the attraction ratings for Profile A and Profile B.
The student researcher decided herself which attitudes were similar and which were different.
Explain how the study could be improved by selecting or categorising the profiles another way.
