How do you find Mean, Median, Mode, Range, Standard Deviation and Variance?

Mean = Average = = Sum of all Numbers / Number of Numbers in List.

Median = Center Number of Ordered List

Mode = The most frequent Number in List

Range=Largest – Smallest Number in List

Variance of Population :

where μ = Population Mean

Standard Deviation of Population :

Variance of Sample :

Standard Deviation of Sample :

How do I calculate Mean, Median, Mode and Range?

Mean Median Mode Range
Mean Median Mode Range

Let’s do an Example with 7 numbers (see right image)

a) To find the Mean we add up the 7 integers to get 80 and divide by 7 to get a Mean of 80/7 = 11.4 . Note: Mean is also called Average.

b) To find the Median we simply identify the center number to get a Median = 6. In case of 2 center numbers we will average them.

c) To find the Mode we simply identify the most common number to get a Mode = 1. Note: We may have 2 or more modes.

d) To find the Range we simply subtract the Minimum from the Maximum to get a Range = 42 – 1 =41.

e) Outliers are numbers that are way off.
