Frequency Distributions

The idea
A frequency distribution lists each score, or range of scores, with the number of students who earned it; a histogram draws the same information as bars, so the shape of a set of scores can be seen at a glance.
In practice
Five students scored 8, seven scored 9 and two scored 10.
Where people slip
Organizing scores comes before summarizing them with statistics.
