The standard deviation is the most frequently used measure of variation because it takes into account all the data points and provides a measure of how spread out the data is from the mean. The range is not as reliable as it only considers the highest and lowest values. The variance also takes into account all the data points, but is not as commonly used as it provides a measure of dispersion that is squared, making it less interpretable.
