Quizplus · Accepted Answer

Variance is defined as the average of squared differences from the mean. It is calculated by subtracting the mean from each score, squaring the difference, summing the squared differences, and dividing by the number of scores. Therefore, option D, i.e. the average squared distance from the mean is the correct answer.
