In statistics, this is the symbol for the "Variance"
The population mean is the mean value of the entire population. Contrast this with sample mean, which is the mean value of a sample of the population.
d bar, d with a bar over it
It means the sum total.
Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.

it means the common symbols and expression used in mathematics,geometry and statistics.
Greek letters are used for population parameters. Eg: µ is the population mean English letters are used for sample statistics. Eg: x-bar is the sample mean
N is neither the sample or population mean. The letter N represents the population size while the small case letter n represents sample size. The symbol of sample mean is x̄ ,while the symbol for population mean is µ.

In statistics, "mu" is often used to represent the population mean of a variable. It represents the average value of a given data set in the entire population.
INFERENCES Any calculated number from a sample from the population is called a 'statistic', such as the mean or the variance.
