Abstract

We present a metric to calculate the idealized standard deviation (ISD) in the event that ties are possible and receive points in team-sport league standings. Our aim is to raise some issues regarding the customary application of that concept in leagues that do not employ a binomial system for determining rankings, to suggest that the reciprocal of the ISD may be a more intuitive construct if the intent is to represent parity, to provide scholars with a set of ISDs, and to suggest some interesting topics that arise from a quick perusal of the time series.
