Math Help: Range, variation and standard deviation

Refresh your competency in the various areas of Mathematics.

RANGE, VARIATION AND STANDARD DEVIATION

In this module, you can study the basic statistical measures of dispersion: range, variance and standard deviation.

 

The video above is a good explanation from Khan Academy about statistical measures of dispersion: range, variance and standard deviation.

Did you know?

Variation and standard deviation both show how spread out the data set is. 

A data set of any size can have a large or a small standard deviation.
