Given these two data sets, IQ-GPA and IQ-SAT, how would you predict Justin’s SAT score based on his GPA? Explain.

Answer:

To predict Justin's SAT score from his GPA, I would first use the trend line equation for the IQ-GPA data set to find the IQ score that corresponds to his specific GPA. Once I have that IQ value, I would use the trend line equation for the IQ-SAT data set to calculate the SAT score predicted for that IQ.
