Identify and interpret the correlation coefficient and coefficient of determination in the data table

According to the data in the table illustrated above, the HRR parameters are negatively correlated with majority of the metabolic risk factors. These include the waist circumference, SBP, levels of serum triglycerides as well as the serum CRP levels. This is owing to the fact that the coefficient correlations of these parameters from the multiple linear regression analysis were negative, for both boys and girls. However, on the other hand, the coefficient correlations if serum HDL levels were positive which shows that this parameter is positively correlated with HRR (Lin et al., 2008).
