Question

Quizplus · Accepted Answer

A positive correlation coefficient indicates a direct relationship between the two variables, meaning as one variable (in this case weight) increases, the other variable (in this case heart disease) also increases. A correlation coefficient of .57 indicates a moderate positive relationship between weight and heart disease, which supports the findings of the study. Choices A, B, and D are all incorrect because they indicate no correlation, a weak negative correlation, and a strong negative correlation, respectively, which do not accurately describe the relationship between weight and heart disease in the study.
