Answer 1

Answer: The median score of Ms. Singh's 20 students is 82.5

Step-by-step explanation: What are mean and median?

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

A Median represents the middle value of the given data when arranged in a particular order.

We are given the Students in Ms. Singh's class had the following scores on their last quiz.

First, we have to arrange the given data in an ordered manner. Thus:

55, 68, 72, 73, 75, 77, 78, 79, 82, 82, 83, 85, 85, 85, 86, 86, 87, 91, 92, 95

The median = the average of the 10th and 11th data

Median = (82 + 83) ÷ 2

Median = 165 ÷ 2

Median = 82.5
