Researcher wondered whether the size of a person's brain was to related to the individual's mental capacity. The selected 3 females and 3 males measured their MRI counts IQ scores. The data is below.
Females Males
MRI IQ MRI IQ
857,781 135 924,060 138
991,305 138 965,355 132
856,473 141 1,038,438 138
Treat the MRI as the explanatory variable. Compute the linear correlation coefficient between MRI count and IQ for both the males and the females. Do you believe that MRI count and IQ are linearly related?
A-the linear correlation coefficient for females is?
B- the linear correlation coefficient for males is?
