WebThe mean of this variable is 2.57, and the standard deviation is 0.60. The authors used appropriate measures of dispersion for this variable by reporting the standard deviation. Other measures of dispersion that could have been used include the range or interquartile range, but the standard deviation is the most commonly used measure of dispersion.
WebMeasures of dispersion, on the other hand, are statistics that describe how spread out the data in a data set is. Examples of measures of dispersion include the range, interquartile range, and standard deviation.
