A researcher is surprised at the low Pearson Product Moment correlation coefficient between the heights and weights of the members of the woman’s basketball team at his college.  He should have realized

a. that he had several outliers and that reduced the correlation

b. the range of heights was restricted and that reduced the correlation

c. the relationship was curvilinear and could not be detected by the Pearson Product Moment correlation

d. Height does not cause weight
