Measuring the Variability of Data from Other Values in the Set
Jones, Dustin L.; Scariano, Stephen M.
Teaching Statistics: An International Journal for Teachers, v36 n3 p93-96 Aut 2014
Students have intuitive notions of the meaning of variability; some may see variability as how values in a set vary from each other. This article provides a measure of variability that is based on that conception. We introduce this new measure and a method for calculating it. Finally, we prove that this measure is equivalent to the population variance.
