Line Graphs and Line Plots REVIEW

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 used to show trends over time.

What is a line plot?

Back

A line plot is a simple way to display data along a number line, showing the frequency of data points. Each data point is represented by an 'X' above the corresponding value.

How do you find the median in a data set?

Back

To find the median, arrange the data points in numerical order and identify the middle value. If there is an even number of data points, the median is the average of the two middle values.

Front

What does it mean if a line graph is increasing?

Back

An increasing line graph indicates that the values are rising over time, showing a positive trend.

Front

What does it mean if a line graph is decreasing?

Back

A decreasing line graph indicates that the values are falling over time, showing a negative trend.

Front

How can you identify the mode in a data set?

Back

The mode is the value that appears most frequently in a data set. It can be found by counting the occurrences of each value.

Front

What is the purpose of using a line plot?

Back

A line plot is used to visualize the distribution of data points and to easily identify trends, clusters, and gaps in the data.

Front

What type of data is best represented by a line graph?

Back

Line graphs are best for continuous data that changes over time, such as temperature, stock prices, or population growth.

Front

What is the difference between a line graph and a bar graph?

Back

A line graph shows trends over time with connected data points, while a bar graph compares different categories using rectangular bars.

Front

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

Back

The slope of a line in a line graph indicates the rate of change. A steeper slope means a greater rate of change.
