Avoid calculating the square root of negative zero, which can easily happen on certain architectures when calculating the population standard deviation with a sample size of one, e.g., 0.01 - (0.1 * 0.1) = -0.000000. Avoid returning a NaN by capping the minimum possible variance value to zero (positive). In the future, maybe skip reporting statistics at all for a single sample.
