All the students of a class performed poorly in Mathematics. The teacher decided to give grace marks of 10 to each of the students. Which of the following statistical measures will not change even after the grace marks were given ?

TestHub · Accepted Answer

As we know that with the change in origin, the variance does not change.

Therefore, variance does not change even after giving grace marks of $10$ to each of the students.

Whereas, mean, mode and median changes upon changing the origin.
