Nice and easy to use. Thanks.
Generated good level of discussion - used this as an introduction to measures of spread. Interesting to see how many understand what happens when you sum the differences from the mean! Thanks.
This is a nice resource to use for A-level Statistics students, a set of numbers are given and then descriptions of possible methods for measuring the spread. The name of each measure is not given so a good start would be for students to try and put a name to each method. They then have to give a pro and con to each. This would be a nice rich task to get students to do having studied measures of spread and would give you a good insight into their level of understanding. Thank you for sharing.
