Grades 6–7AlgebraGuided journey: Discover, Learn, Practice, Apply

The everyday graphs that turn a table into a picture: frequency tables, bar graphs for comparing categories, line graphs for change over time, and circle graphs for parts of a whole, plus how to read a graph by its title, labels, and scale. Companion to Statistics: Center, Spread & Plots, which owns dot plots, histograms, and box plots.

What you’ll learn

A frequency table counts each category; the counts add to the group total.
Bar graphs compare separate categories; line graphs show change over time; circle graphs show parts of a whole.
A circle graph slice is the part over the total, as a percent of $100\%$ or an angle of $360°$ .
Read a graph by its title, axis labels, and scale before pulling a value.
