I agree with this. Fekade pointed out that Spearman correlation is based on ranking the scores and hence should be used with ordinal data. In question 9.2, the distribution of variable mother’s education is lightly skewed (skewness =1.124) (Morgan et al., 2013, p.59), which is a violation of the assumption of Pearson correlation.

In D 6.2, Fekade interpreted output of 9.3 and concluded that the students who have highly scholastic aptitude test-math tend to have higher math achievement test scores and vice versa. I agree with his interpretation. Fekade also explained the adjusted regression coefficient as
