Question

Data: 70, 71, 71, 70, 72, 73, 72, 73, 74, 74, 75, 76, 75, 76

What is the median

Answer 1

73

Explanation:

When finding the median, if the number of variables is odd, the median is the number in the middle. If the number of variables are even, the median is the average of the two variables in the middle of the sequence.

In this case, we have 14 variables, so we have to calculate the median with the two numbers in the middle, 73 and 73. The average of these numbers are 73, so the median of the data set is 73.

Answer 2

73

Explanation:

70, 71, 71, 70, 72, 73, 72, 73, 74, 74, 75, 76, 75, 76

Write numbers in ascending order:

70, 70, 71, 71, 72, 72, 73, 73, 74, 74, 75, 75, 76, 76

There are 14 numbers. Take the middle 2 numbers and find the mean.

70, 70, 71, 71, 72, 72, 73, 73, 74, 74, 75, 75, 76, 76

(73 + 73)/2 = 73

The median is 73.
