The range provides only a rough indication of the degree of variation among a set of scores as it only takes into account the difference between the highest and lowest scores, without considering the distribution of scores in between. The standard deviation provides a more precise measure of variation by taking into account the deviation of each score from the mean, while the median is a measure of central tendency and the correlation is a measure of the relationship between two variables.
