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. It is used to show trends over time.

What does it mean when a line graph is increasing?

Back

An increasing line graph indicates that as one variable increases, the other variable also increases. For example, more hours worked may lead to more money earned.

What is a circle graph (pie chart)?

Back

A circle graph, or pie chart, is a circular statistical graphic divided into slices to illustrate numerical proportions. Each slice represents a category's contribution to the whole.

How do you determine the least popular option in a circle graph?

Back

What is the purpose of a bar graph?

Back

A bar graph is used to compare different groups or categories. Each bar represents a category, and the height or length of the bar indicates the value or frequency of that category.

Front

What does it mean if a bar graph has equal heights for different categories?

Back

If a bar graph has equal heights for different categories, it means that those categories have the same value or frequency.

Front

How can you find the total number of participants in a survey from a bar graph?

Back

To find the total number of participants in a survey from a bar graph, add the values represented by each bar.

Front

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

Back

The x-axis (horizontal) typically represents the independent variable, while the y-axis (vertical) represents the dependent variable. Together, they help to plot data points.

Front

What does a steep slope in a line graph indicate?

Back

A steep slope in a line graph indicates a rapid change in value. For example, a steep increase means a quick rise in the dependent variable.

Front

What is a data point in a graph?

Back

A data point is a single value that represents a specific observation in a graph, typically plotted as a dot or marker.
