Bar Graphs and Line Graphs

Front

What is a bar graph?

Back

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

Front

What is a line graph?

Back

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments.

Front

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 for each category.

Front

How do you read a line graph?

Back

To read a line graph, observe the points plotted on the graph and follow the lines to see how values change over time.

Front

What does the x-axis represent in a graph?

Back

The x-axis is the horizontal line on a graph that typically represents categories or time.

Front

What does the y-axis represent in a graph?

Back

The y-axis is the vertical line on a graph that usually represents the values or quantities.

Front

What is the purpose of a title in a graph?

Back

The title of a graph explains what the graph is about, providing context for the data presented.

Front

What is a data point?

Back

A data point is a single piece of information represented on a graph, usually shown as a dot or a bar.

Front

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

Back

To find the difference, compare the heights of the two bars and subtract the smaller value from the larger one.

Front

What does it mean if a line graph is increasing?

Back

If a line graph is increasing, it means that the values are getting larger over time.
