This research note demonstrates that M1 and M2, two of the six measures of the division of labor discussed by Gibbs and Poston, commonly conceptualized as measures of qualitative variation, can be interpreted in terms of the expanded binomial probability model. M1 is the variance of the expanded binomial probability model and M2 is the ratio of the variance of the expanded binomial model to the variance of a binomial model.
