Document Summary

Variability: the manner in which the scores are scattered around the centre of the distribution. Range: the difference between the highest and lowest scores in a distribution. Inter-quartile range: the range (or difference) between the first and third quartiles; the range containing the middle 50% of a distribution. Variance: the mean of the squared deviations from the mean of a distribution. Standard deviation: the square root of the mean of the squared deviations from the mean of a distribution. A measure of variability that reflects the typical deviation from the mean. Coefficient of variation: a measure of variability that is independent of the unit of measurement. It is calculated by dividing the standard deviation of a distribution of scores by the mean.
