Question

The final exam scores of 20 introductory statistics students are represented by the set {3, 1, 7}. What is the median of these scores?

a) 3
b) 5
c) 7
d) 10

Answer 1

The median of the set {3, 1, 7} is 3.

Step-by-step explanation:

The median is the middle value when a set of numbers is arranged in order. To find the median of the set {3, 1, 7}, we first need to arrange the numbers in ascending order: 1, 3, 7.

The middle value is 3, so the median of the set is 3.
