Back

A linear relationship appears as a straight line or a pattern that closely resembles a straight line.

What is the purpose of a trend line in a scatterplot?

Back

A trend line is used to summarize the relationship between the variables and to predict future values.

Front

What does it mean if a scatterplot shows no correlation?

Back

No correlation means that there is no discernible relationship between the two variables; the points are scattered randomly.

Front

What is the x-axis in a scatterplot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatterplot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.
