A Visual Model for the Variance and Standard Deviation
Orris, J. B.
Teaching Statistics: An International Journal for Teachers, v33 n2 p43-45 Sum 2011
This paper shows how the variance and standard deviation can be represented graphically by looking at each squared deviation as a graphical object--in particular, as a square. A series of displays show how the standard deviation is the size of the average square.
