Question

There are 29 students in Mrs. Dixon's science class. On the last test, only 1 student earned the median score of 84.

How many students scored an 84 or lower?

A - 15
b - 14
C - 13
D - 12

Answer 1

A

Explanation:

Median can be described as the number that occurs at the middle of a set of observations.

for example, in the set of numbers, 1 2 3 4 5, the median is 3

median = (first number + last number) / 2

If there are 29 students,

median = (1 + 29) / 2 = 30/2 = 15

the 15th students scored 84

and students between 1 - 14 scored lower than 84

so, 15 students scored an 84 or lower
