A scatter plot graphically displays two related sets of data. Such a visual representation can indicate patterns, trends and relationships.
To perform a scatter plot on a graphing utility,
· First list the given points using the STAT then EDIT menu. Next graph the scatter plot using the STAT PLOT feature.
· The shape of the data points on the scatter graph can help determine which regression feature to use.
· Once this is determined, select the appropriate regression analysis command from the STAT then CALC menu.
