● Population Variance ○ If N is the number of values in a population with mean mu, and xi represents each individual in the population, the the population variance is found by: ○ σ 2 = sumN i=1 (xi − µ) 2 N ○ and the population standard deviation is the square root, σ = √ σ 2. ○ Most of the time we are working with a sample...
