Quizplus · Accepted Answer

The correct order for computing variance is: first, compute the mean of the sample (4); then, subtract the mean from each score to find the deviations (2); next, square each of the deviation scores to eliminate negative values and give more weight to larger deviations (5); then, add up the squared deviation scores to get the total squared deviation (3); and finally, divide the sum of squared deviations by the number of scores to find the average squared deviation, which is the variance (1).
