Answer 1

mean=85

median=84

mode=80

range=17

Explanation:

How to Find the Mean

• Add up all data values to get the sum

• Count the number of values in your data set

• Divide the sum by the count

How to Find the Median

• Arrange data values from lowest to the highest value

• The median is the data value in the middle of the set

• If there are 2 data values in the middle the median is the mean of those 2 values.

How to Find the Mode

• Mode is the value or values in the data set that occurs most frequently.

How to Find the Range

• First, put all the numbers in order.

• Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.
