Sigma is a Greek symbol used for many variables in mathematics and science. However, within statistics, the variance is sigma squared and it is always positive. Sigma is used as the standard deviation of a population, and as calculated, it is always equal or greater than 0 (a positive number). However, in discussing errors, one can consider adding or subtracting sigma, ie the error in our experiment is +/- one sigma from the population.
