Scatter Plot Comparison

A graph with points plotted to show a possible relationship between two sets of data.

• Scatter Plot

• Dot Plot

• Line Plot

• Frequency Table

A line on a scatter plot that helps show the correlation between data sets more clearly is called (a)   .

• Trend Line

• Line of Reflection

• Line of Trend Fit

• Frequency

A straight line that comes closest to the points on a scatter plot is called (a)   .

• Line of Best Fit

• Trend Line

• Frequency

• Correlation

Uses dots to represent values for 2 different numeric variables
