Bar Graphs & Pictographs

A bar graph is a visual representation of data using bars of different heights or lengths to show the quantity of each category.

A pictograph is a chart that uses pictures or symbols to represent data, where each picture stands for a certain number of items.

To read a bar graph, look at the height of the bars to determine the quantity for each category.

The height of a bar represents the quantity or value of the category it represents.

Graphs are used to visually display data, making it easier to compare and understand information.

To find the total number of votes, add the heights of all the bars together.

If a bar is taller than another, it means that the category it represents has a higher quantity or value.

The key in a pictograph explains what each picture or symbol represents in terms of quantity.

To compare two categories, look at the heights of their respective bars; the taller bar indicates a larger quantity.

Pictographs are best for representing data that can be easily visualized with pictures, such as favorite fruits or pets.
