Question

The following scores were available for 9 students in a Statistics class 18, 20, 15, 12, 12, 10, 8, 17, 20.The score for the 10th student was missing but it was known to be the second highest score. What would be the median for the distribution?

Answer 1

Answer:

16.

Step-by-step explanation:

If the score was the second highest then it must be 19.

Listing in ascending order:

8, 10, 12, 12, 15, 17, 18, 19, 20, 20

So the median is (15+17)/2

= 16.
