Graphs answer three kinds of question: how many in one group, how many in all, and how many more.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
How many more
That one is a comparison. Find the difference between the two columns.
Some answers are read, some are worked out
"How many chose red" is read straight off. "How many more chose red than blue" needs a subtraction after reading two bars.
A graph only knows what it was asked
If nobody was asked about green, green is missing — not zero. A graph cannot answer a question it never collected.
Step 2: Try It Yourself
Tap and try it out.
Fish
Balls
There are 7 in all.
Fish has the most. It has 3 more than Balls.
Step 3: Watch an Example
One step at a time.
