WebThe purpose for measuring variability is to obtain an objective measure of how the scores are spread out in a distribution. There are three different measures of variability: the range, standard deviation, sonf the variance. Of these three, the standard deviation and the related measure of variance are the most important. Purpose of Good ... WebRange. The range is the difference between the highest and lowest scores in a data set and is the simplest measure of spread. So we calculate range as: The maximum value is 85 and the minimum value is 23. This results in a range of 62, which is 85 minus 23. Whilst using the range as a measure of spread is limited, it does set the boundaries of ...
