Back

If two bars are the same height, it means that the categories they represent have equal values.

Front

How can you find the difference between two values in a bar graph?

Back

To find the difference, compare the heights of the two bars and subtract the shorter bar's height from the taller bar's height.

Front

What is the significance of the x-axis and y-axis in a bar graph?

Back

The x-axis typically represents the categories being compared, while the y-axis represents the values or quantities.

Front

How can you use a bar graph to make predictions?

Back

You can use trends in the bar graph to make predictions about future data points based on past patterns.

What is a key in a bar graph?

Back

A key in a bar graph explains what each bar represents, often using colors or patterns.
