Getting Ready
Graphs are visual representations or pictures of data. They help us to compare data, draw conclusions, make predictions, and see trends.
They are often used in the workplace. You may see graphs that show sales of products, attendance of employees, or the types of customers that buy products.
In this activity, you will learn about two types of graphs: bar graphs and pictographs.
A bar graph or pictograph will start with gathering information.
