Data set b: 87, 90, 77, 83, 99, 94, 93, 90, 85, 83 find the median

88.5

Step-by-step explanation:

First you need to order the data set from least to greatest:

So,

77,83,83,85,87,90,90,93,94,99

Then you find the middle number, in this case it's 87 and 90.

Because there is two middle numbers in the data set, you need to find the average between those numbers.

The average between 87 and 90 is 88.5.

Hope this helps :)
