Practice Reading Graphs

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. It is often used to show trends over time.

Front

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.

Front

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 total.

Front

How do you determine the same height of two plants from a line graph?

Back

Look for the point where the lines representing the two plants intersect on the graph. This point indicates the week when both plants were the same height.

Front

What does it mean to find the difference in values on a graph?

Back

Finding the difference involves subtracting one value from another to determine how much more or less one quantity is compared to another.

Front

How can you predict future values based on a trend in a graph?

Back

To predict future values, observe the pattern or trend in the existing data points and extend that trend to estimate future outcomes.

Front

What is the purpose of labeling axes on a graph?

Back

Labeling axes provides context for the data being presented, indicating what each axis represents (e.g., time, quantity) and the units of measurement.

Front

What is the significance of the scale on a graph?

Back

The scale on a graph determines the intervals at which data points are plotted, affecting how the data is interpreted and visualized.

Front

How do you interpret the slope of a line in a line graph?

Back

The slope of a line indicates the rate of change between the two variables represented. A steeper slope means a greater rate of change.

Front

What does a flat line in a line graph indicate?

Back

A flat line indicates that there is no change in the value of the variable over the period represented.
