Can you help me with replying to the discussion post: There are two ways to show the variability of data. The first is to use a range which is less than desirable but is also the easiest. It is not a great way to display variability because it is merely the difference between the highest and the lowest scores. Meanwhile standard deviation is how we display summarized data that is interval or ratio. This is the most common measure of variability. It tells you the typical, or standard distance each score is from the mean
