Mean (statistics)
From Simple English Wikipedia, the free encyclopedia
- Also look at mean if you did not find what you were looking for.
The Mean is a measure from mathematics or from statistics. If people do many different measurements, they will get many different results. Those results have a certain distribution, and they can also be centered around an average value. This average value is what mathematicians call arithmetic mean.
The problem with using the mean is that the information about how the values are distributed is lost.
This is different to the Median. The median is the number that divides all the samples in such a way that half of the samples are below it, and the other half above.
The modus or Mode is the number with the greatest number of samples, or observations.
