It means the sum total.
in statistics, summation denoted by upper case sigma, is used to find the sum of a series of observation in a particular variable.
Coefficient of deviation (CV) is a term used in statistics. It is defined as the ratio of the standard deviation (sigma) to the mean (mu). The formula for CV is CV=sigma/mu.
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.
No/FALSE
