Which graph shows how data are spread out?
A scatter diagram.
What shows how the data set as a whole is spread around the mean?
In statistics a Bell curve is the most common way that the distribution of results is plotted. If you know the mean and the standard deviation you can predict with that distribution with reasonable accuracy.
Which graphic display shows the median and data spread about the median?
A frequency diagram or, for grouped data, an histogram.
