Data & Graphs
📋 What it is
Graphs show data visually — bar charts compare amounts, line graphs show change over time.
🗣️ Coach says
A graph turns a table of numbers into a picture you can read at a glance. Bar charts compare separate groups; line graphs show how something changes over time. Choosing the right graph makes the story obvious.
🧠 Memory hook
Bar chart = compare groups. Line graph = change over time. Match the graph to the question.
