Key Concepts
- The x-axis of a scatterplot shows values of the independent variable.
- The y-axis of a scatterplot shows values of the dependent variable.
- If high values of x are associated with high values of y, there is a positive relationship.
- If high values of x are associated with low values of y, there is a negative relationship.
- The strength of a relationship can be seen based on how close the points are to a line or a curve.
- Departures from the general pattern can also be seen in a scatterplot.
Glossary
Scatterplot: a graph that plots points. Each point represents an ordered pair, where the x-value is a value of the independent variable and the y-value is a value of the dependent variable.
