The Arithmetic Mean

One of the most well known statistical parameters is the arithmetic mean, colloquially also known as 'the average'.

Usage of the AM is possible with
­ interval variables
­ ratio variables (all values are possible).

(These conditions are not being met for e.g. grades for school exams, even though the AM for grades is frequently calculated and used!)

Change the values on the scale by dragging and dropping them with your mouse. Try to observe the consequences of your changes for the arithmetic mean (AM).
