Question

The amount of time George takes to run 1 mile in eight consecutive days is as shown below.

Ava says that the median will be from the data set.
Elijah says that the median will not be from the data set.
Who is correct?

• A. Ava
• B. Elijah
• C. Both Ava and Elijah
• D. Neither Ava nor Elijah

Answer 1

The correct option is B Elijah

Median is the middle value of a numerically ordered data set.

Arranging the duration in ascending order, we get:
9, 9, 10, 10, 11, 11, 12, 12.

Since the total number of data points is even, the median is the mean of the two central values of the data set arranged in ascending order.

Thus, median = $\frac{10+11}{2}$ = 10.5

Hence, the median is not from the data set and Elijah is correct.
