Question

Quizplus · Accepted Answer

The variance is calculated by taking the average of the squared deviations about the mean. It measures how spread out the data is from the average. Option B is describing the range, which is a measure of how far apart the highest and lowest scores are. Option C is describing the sum of the deviations from the mean, which would be 0 if the data is perfectly symmetrical. Option D is describing the standard deviation, which is the square root of the variance.
