Quizplus · Accepted Answer

The population variance is defined as the squared differences of each score from the mean of a population divided by the population size. This is the formula for population variance:

σ² = Σ(x-μ)²/N

where σ² is the variance, Σ is the sum, x is each individual score in the population, μ is the population mean, and N is the number of scores in the population.
