In the checksums, you validated that the average SAT score for all of the records is 1,059.07. When we work with the data more rigorously, several tests will require us to transform NULL or blank values. If you were to transform the NULL SAT values into 0, what would happen to the average (would it stay the same, decrease, or increase)? AQ2. How would that change to the average affect the way you would interpret the data? AQ3. What would happen if we excluded all schools that don’t report an average SAT score?
