Mean: 98.8

Add all numbers and then divide the sum by the number of values.

5+106+100+50+165+40+100+30+100+125+180+145+110+115+100+110

= 1,581 ÷ 16

= 98.8125

Median: 103

Put the numbers in order from least to greatest, then find the value in the middle. If there are two values in the middle, add them together and divide the sum by 2.

5, 30. 40. 50, 100, 100, 100, 100, 106, 110, 110, 115, 125, 145, 165, 180

= 100 + 106

= 206 ÷ 2

= 103

Mode: 100

The mode is the most frequent value.

5, 106, 100, 100, 100, 100, 50, 165, 40, 30, 125, 180, 145, 110, 110, 115

The value 100 appears four times, which is the most frequent.

so the mode is 100.

Hope this helps :)
