Sancho believes that the relationship between the two variables he is investigating is curvilinear. The Pearson product-moment correlation coefficient will provide a good index of the strength of this relationship.
A. True
B. False
An investigator conducted a study to find the relationship between the number of decayed, missing, or filled teeth (DMFT) and sugar consumption. The investigator produced an estimate for the correlation coefficient and provided the following statement: “The correlation between DMFT and sugar consumption is 0.7.
State why you are or you are not confident about this investigator’s conclusion. In other words, explain if something is missing from this investigator’s analysis, or if all you need is provided.
The Pearson's r correlation between two variables X and Y is calculated to be 0.6. What can be concluded from this correlation coefficient about the relationship between X and Y?
