A good chart turns a column of numbers into a picture you can understand at a glance. Bar charts compare quantities, pie charts show how a whole is shared, and stem-and-leaf diagrams keep the data while showing its shape. Choosing and reading the right chart is a core data skill.

In this lesson you will draw and interpret bar charts, pie charts, pictograms, stem-and-leaf diagrams and simple frequency distributions.
