Scott is trying to choose between two doctor offices and gets a distribution from each one that shows the number of minutes a
patient typically has to wait at the office.
Would he be able to accurately describe the variability of each graph by only stating one measure of spread?
Yes, the variability of any distribution can be accurately described using
one measure of spread.
No, since the first graph has 2 clusters a single measure of spread without
further explanation could be misleading
No, you can never use a single measure to describe the spread of a
distribution you must give all measures of spread.
Yes, even though the first graph has 2 clusters since the second graph
could be described using a single measure he can do so for both.
