The lowest value of variance can be 0, which indicates that all the values in a dataset are identical. Variance measures the dispersion of a set of data points around their mean value, and a variance of 0 means there is no dispersion. Negative variance is not possible because variance is calculated as the average of the squared differences from the Mean, and squaring any real number results in a positive number or zero.
