A data analyst wants to highlight large deviations by squaring the distance of each value from the average. Which measure best aligns with this goal?
Range
Standard deviation
Variance
Interquartile range
The calculation that squares each distance from the average and then computes an average of those squared values is known as variance. While standard deviation is derived from variance by taking the square root, variance directly represents the average of squared deviations. Range and interquartile range measure overall spread or the spread of the middle half of the data but do not incorporate the squaring of individual deviations from the mean.
