===Meaning===
A '''mean average''' is when you add up all the numbers and divide by the number of numbers.

===About a Mean Average===
: A '''mean average''' is used in science to reduce the effects of [[Random Error|random errors]] in the [[results]] of an [[experiment]].

===Calculating a Mean Average===
Results: 5,3
: <math>Average = \tfrac{5+3}{2}</math>
: <math>Average = 4</math>

Results: 7.0, 6.8, 7.8
: <math>Average = \tfrac{7.0+6.8+7.8}{3}</math>
: <math>Average = 7.1</math>

Results: 12.3, 11.7, 11.4, 12.1
: <math>Average = \tfrac{12.3+11.7+11.4+12.1}{4}</math>
: <math>Average = 11.875</math>
: <math>Average = 11.9</math>
