Let me count the problems here.
Sample size=70 students-microscopic.
Sample group= all from same school, very little diversity
duration of test=3 days
The lack of diversity, short duration and small sample size of this "study" says nothing about the population at large. you cannot possibly even begin to rule out any of the really important variables with these systemic flaws in the study.
Might be good enough for a high school project but I would expect much higher standards than this from a university. Is this what people are paying 10s of thousands of dollars on education to learn to do these days?
