We are awash in tables, charts, and graphs. Newspapers display data in every section—from economic information to sports statistics to weather reports. Even the entertainment section features data on television and movie viewing.

As a result, scientific literacy is absolutely dependent on people being able to create and—more importantly—understand the meaning behind all of these data displays.
