Why is it important to check your descriptive statistics against a visual graph of the data?
(a) The graph shows you whether the descriptive statistics are sensible representations of the numbers
(b) The descriptive statistics will always be the same regardless of the graph, which is not very important
(c) The graph will always show that the descriptive statistics make sense for the data, so it is for double-checking a correct answer
(d) The graph can only show you whether your measures of central tendency are appro-priate for the data, but not measures of variation
