Referring to Applied Example 14. 15:
a. Explain the meaning of “the mean scores are significantly different (p = 0.0001) What mean scores are being referred to? What methodology might have been used to establish this significance?
b. Explain the meaning of “Pearson correlation analysis shows that VMI scores in the two studies were significantly correlated (r = 0.60 p = 0.0001)
c. Explain the meaning of “Spearman’s rank correlation coefficient was also highly significant (r = 0.57 p = 0.0001).”
d. What is the relationship between the Pearson correlation and Spearman correlation analysis?
