Question

Warren reviews his progress report and notices the following grades: 85, 98, 72, 30, 100, 90, 80, 100,78 Find the median of his grades.

Answer 1

The median of the set of numbers is 85

Step by step explanation:

The median is the middle number in a sorted, ascending, or descending. To calculate the median we are going to follow these steps:

1. Arrange your numbers in numerical order.

`30,72,78,80,85,90,98,100,100`

2. If you have an odd number of total of the number, divide by 2 and round up to get the position of the median number. If you have an even number, divide by 2, go to the number position and average it with the number in the next higher position to get the median.

`(9)/(2)=4.5\approx5`

Then, the median would be the number in position 5:

The median of the set of numbers is 85
