research psychology: Using Statistics-Conducting a quasi-experiment

Conduct a "quasi-experiment" by gathering the following data: age and height of 20 people. Then plot in a scatterplot (by hand or using a graphing software program such as Microsoft Excel). What does the data tell you?

NOW: Using the data you collected, calculate the mean, median, and mode, and then plot these on the same graph as the scatter diagram. What does the diagram tell you? Consider multiple contextual factors.
