Two principal points of symmetric, strongly unimodal distributions

Statistics & Probability Letters, 1994, vol. 20, issue 4, 253-257

Abstract: Examples illustrate that splitting a symmetric, unimodal distribution into two groups so as to minimize the sum of the within-group variances does not always occur at the mean. Strong unimodality is shown to be a sufficient condition for the optimal cutpoint to occur at the mean.
