  1. Making Scatterplot Graphs

  2. 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.

  3. 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.
