Making Scatterplot Graphs

A Scatterplot is a graph that compares two quantitative variables. Each pair of values (one from each category) is represented on the graph with a dot.


Association between variables l.jpg

Association between Variables

  • Two variables are associated if some values of the first variable tend to occur more often with some values of the second variable than with other values of that variable.

  • Positive Association: high values for the first variable occur with high values for the second variable

  • Negative Association: high values for the first variable occur with low values for the second variable.
