14.1 Essential Ideas
The classification and tabulation of data into classes is called a frequency distribution. This section considers different graphical ways of interpreting data including the stem-and-leaf plots, bar graphs, line graphs, circle graphs, and pictograph’s. This section also discusses possible misuses of graphs.
