Question

Sam had four tests last month. His scores were 81, 94, 83, and 91. What is the median of his scores?

Answer 1

Answer:

To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

81,83,91,94

since its an even number add up the two middle numbers 83 and 91 to equal 174 then divide by two to have the median of 87

Step-by-step explanation:

Answer 2

Answer:

The answer is 87.

Step-by-step explanation:

First, line up the data in order: 81, 83, 91, 94. Next, take off the numbers at the ends until you reach the middle number. Since there is no middle number in this problem, you have to find out the middle of 83 and 91 by lining them up in order: 83, 84, 85, 86, 87, 88, 89, 90, 91. The answer would then be 87.
