Understanding Scatter Plots

What is a scatter plot used for?

• To compare parts of a whole

• To display a single variable over time

• To show the relationship between two variables

• To show changes in data over intervals

On which axis is the independent variable plotted in a scatter plot?

• W-axis

• X-axis

• Z-axis

• Y-axis

What does a positive correlation in a scatter plot indicate?

• Values of one variable decrease as the other increases

• Values of both variables increase together

• Values of both variables decrease together

• No relationship between the variables

What is the 'line of best fit' in a scatter plot?

• A line that is closest to all data points

• A line that is farthest from all data points

• A line that connects all data points

• A line that divides the data points into two equal groups
