Answer
Section 1:
As the correlation coefficient is 0.68 between the website and the in-class responses, it indicates that the ratings were a good representation of the method of teaching.
A high correlation coefficient between the two variables means that the ratings and the feedbacks given were accurate and not misleading. They gave an adequate knowledge about the teachers and were indeed informative.
Section 2:
An argument against RateMyProfessors.
There is a high correlation due to the teacher’s physical qualities and not due to the method of teaching, which can be misleading.
The correlation between the good looks and the quality of the teacher is 0.64. The value is above average, but is disclosing information about the teacher’s sexiness and his physical qualities and not on how well he teaches. As this can be misleading, this is not an appropriate tool for evaluation purposes.
