    The symbol for standard deviation is s

    The symbol for population and the standard deviation is Sigma

    The symbol for sample population is sigma sigma squared

    The symbol for population variance is sigma squared.

    Explanation:

    Sigma square is the sum of X minus the mean squared divided by n.

    Sigma is a standard deviation, is the measured amount of variation or dispersion of a set of values. The standard deviation is the random variables, statistics variables, data set and the probability distribution is the square root of its distribution.
