  2. History of Scatter plots • Early Origins: There is not one solely credited person that discovered the scatter plots. • First came the creation of the pie charts, line graphs, and bar graphs which are accredited to William Playfair. • All of these have been considered to be very important contributors to the invention of the scatter plot. • Francis Galton was one of the first to demonstrate this type of graph.(Wiley 2005)

  4. Social and Cultural Connections • Currently in the United States, it is approximated that about 70 to 80 percent of graphs used are scatter plots. (Wiley 2005) • Many farmers use scatter plots to estimate the amount of harvest for the upcoming year, and the cost to produce the food. • Cities use them to estimate the population growth over the years

  5. Occupations That Use Scatter Plots • Psychologist use scatter plots and line of best fit to find correlations among test with their patients. • Scientist use them to track earthquakes. It allows them to track time for their warning signals between the “weak waves” and the “strong waves.” • Weather forecasters use scatter plots and line of best fit to compare their predictions versus the actual weather to find their accuracy. (Wiley 2005)

  6. Importance in Future Math • Many topics in math use scatter plots: • Statistics • Algebra • Probability

  7. Line of Best Fit • Line of best fit is very important factor in the scatter plots. • It allows a prediction of results and an average description of what's going on in the experiment. • The line of best fit must more or less follow the direction of the points and they should have roughly the same number of points on each side of the line. (Willis 2011)

  8. Objective of the Game Allow Barbie have the greatest thrill while still ensuring she is safe. This means she comes to the ground as close as possible without hitting the ground. We will use the scatter plot and the line of best fit to determine the number of rubber bands that Barbie will need to survive a 400 cm jump (or approximately 13 ft.)
