SCATTERGRAM

The scattergram is a graph that identifies the relationship between two variables. It consists of an x-axis (horizontal), a y-axis (vertical), and plots that reflect instances of axial relationships.

The scattergram offers several benefits. It is not only easy to build, but it is also easy to interpret. It can also show the relationship between two variables and can identify anomalies. Finally, it can identify the measure of central tendency, or average.

for Building and Interpreting a Scattergram

• Identify the two variables.
• Draw the x- and y-axes, reflecting cumulative graduations of scale.
• Record the instances of the relationship between the two variables.
• Plot the data.
• Draw a line that bisects the main body of the plots to reflect the average.
  • Note: Observe all anomalies (plots outside the main body).
• Conduct further research to identify the contributors to the average and the anomalies.
