# Create and Interpret Column Graphs II

Lesson

Column graphs help to paint a picture of the data we are looking at, making it visually very simple to compare information. The way we create a column graph doesn't really change, but what we include in it may change, so once you learn how to create one, you can change it slightly for the next time.

#### Worked examples

##### Question 1

John had $7$7 blue marbles, $4$4 black marbles, $8$8 yellow marbles, $13$13 white marbles, and $6$6 red marbles. Use this information to complete the column graph.

##### Question 2
