Line Graphs and Bar Graphs

Front

What is a line graph?

Back

A line graph is a type of chart that shows information as a series of data points called 'markers' connected by straight line segments. It is used to display data that changes over time.

What is a bar graph?

Back

A bar graph is a chart that presents categorical data with rectangular bars. The length of each bar is proportional to the value it represents.

How do you read a line graph?

Back

To read a line graph, look at the x-axis (horizontal) for the time or category and the y-axis (vertical) for the value. Follow the line to see how the value changes.

Front

How do you read a bar graph?

Back

To read a bar graph, look at the categories on the x-axis and the values on the y-axis. The height of each bar shows the value for that category.

Front

What does the slope of a line in a line graph represent?

Back

The slope of a line in a line graph represents the rate of change. A steep slope indicates a rapid change, while a flat slope indicates little or no change.

Front

What is the purpose of a title in a graph?

Back

The title of a graph explains what the graph is about, helping the viewer understand the data being presented.

Front

What are the axes in a graph?

Back

The axes are the two lines that form the framework of a graph. The horizontal line is called the x-axis, and the vertical line is called the y-axis.

Front

What is a data point?

Back

A data point is a single value that represents a measurement or observation in a graph.

Front

How can you compare two sets of data using graphs?

Back

You can compare two sets of data using graphs by plotting them on the same graph, allowing you to see differences and trends visually.

Front

What does it mean if a bar in a bar graph is taller than another?

Back

If a bar in a bar graph is taller than another, it means that the category represented by the taller bar has a greater value than the category represented by the shorter bar.
