What is a bar graph?

Back

A bar graph is a visual representation of data using bars of different heights or lengths to compare quantities across categories.

What is a picture graph?

Back

A picture graph is a visual representation of data that uses images or symbols to represent quantities, making it easier to understand for younger audiences.

How do you read a bar graph?

Back

To read a bar graph, look at the height or length of the bars to determine the value they represent, and compare the bars to see differences between categories.

What does it mean if two bars in a bar graph are the same height?

Back

If two bars are the same height, it means that the quantities they represent are equal.

Front

What is the significance of the scale on a bar graph?

Back

The scale on a bar graph indicates the increments of measurement on the y-axis, helping to accurately interpret the values represented by the bars.

Front

How can you compare data using a picture graph?

Back

You can compare data in a picture graph by counting the number of pictures or symbols used to represent each category.

Front

What is a key in a picture graph?

Back

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