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 graph 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 each bar to determine the value it represents for each category.

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

To find the total, add the values represented by all the bars in the graph.

The purpose of a pictograph is to make data easier to understand by using images that represent quantities.

You can compare two categories by looking at the heights of their corresponding bars; the taller bar represents the larger quantity.

A bar graph uses bars to represent data, while a pictograph uses pictures or symbols.

Subtract the value of the shorter bar from the value of the taller bar.

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