Solution

The correct option is D 73.5
If the set consists of an even number of terms, then the median is obtained by following two steps as:

Step I: Arrange the given set in ascending order.

Step II: Find the average of the middle two terms.

Samuel recorded his scores in 12 quizzes.

Step I: The ascending order of the given scores is


Step II: The middle two terms are 72 and 75 and their average is obtained by dividing their sum by 2, i.e.,

Average=72+752=1472=73.5

Thus, the median score obtained by Samuel is 73.5.
