ANATOMY OF A SCATTERPLOT A scatterplot graphs the relationship between paired (x, y) quantitative data values. If it is believed that there is a causal relationship, the independent variable (x) is placed on the x-axis, while the dependent variable (y) is placed on the y-axis. Title. Building a Scatterplot: 1) Identify two quantitative variables that appear to have a relationship. If there appears to be a causal relationship, the values of the independent variable (x) are recorded on the x-axis and the values of the dependent variable (y) are recorded via the y-axis. 2) Create a graph with the x-axis containing a scale appropriate to the x variable and a label, which identifies the measurement scale, e. g. seconds. On the y-axis place the scale for the y variable and include a label. 3) Obtain a listing of the paired data values. (The data for this scatterplot are noted below. ) Y-axis variable and measurement scale. 4) Using the (x, y) coordinates, place a mark on the graph for each set of paired values. 5) Add a title and other useful information X-axis variable and measurement scale. Data points for the paired variables. e. g. (8. 59, 27. 70) The data presented in this scatterplot represent the time and distance of eight balsa wood airplane flights. Making the assumption that time in air might affect overall distance, the time variable was placed on the xaxis. The distance variable is presented on the y-axis. Each dot on the graph corresponds to one (x, y) pair from the data set. Data used for this scatterplot
