Bar graphs and picture graphs

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

A picture graph is a type of 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 x-axis typically represents the categories being compared in a bar graph.

The y-axis represents the values or quantities associated with each category in a bar graph.

You can compare data by looking at the heights of the bars; taller bars represent larger quantities.

The title of a graph explains what the graph is about and what data is being represented.

To create a picture graph, choose a symbol to represent a certain number of items and draw the symbols to show the data.

A key in a picture graph explains what each symbol represents and how many items it stands for.

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