Find the mean and median of the following data set: 98, 87, 92, 79, 65, 91, 80, 92, 85, 86.

The mean would be - 85.5

The median would be - 86.5

1st we need to rearrange the data into numerical order:

65, 79, 80, 85, 86, 87, 91, 92, 92

Median is the middle number

that is 86

Mean add them all up and divide by 9

Mean is 84.11
