Question
To know whether their class standing reflect their achieved learning, Prof. Juan would like to
specifically investigate how students perceived their comprehension of the course described in the
following levels:
1 -I did not understand it at all.
2 -I know the definition but the process/method is still vague to me.
3 -I can apprehend the process/method but I am having trouble when applied in real life scenario.
4 -I can execute the process/method when I encountered familiar problem but not too well for
unfamiliar (new) problems.
5 -I am confident with this topic and can execute it when I encounter new unfamiliar problem.
If Prof. Juan suspects that his students, on the average, perceived their comprehension below level 4,
what statistical analysis would you advise?
