A positive correlation coefficient indicates that as one variable increases, the other variable also increases. In the case of height and weight in healthy adults, it can be assumed that as height increases, weight also increases. Therefore, a positive correlation coefficient would be appropriate, and D (+.45) is the closest to representing a moderate positive correlation. Choices A, B, and C are not appropriate because they either indicate a strong negative correlation, no correlation, or a weak positive correlation.
