For the Barbie Bungee lab, the groups used their knowledge about Bivariate Statistics to accurately find the relationship between the number of rubber bands and the length barbie fell. After identifying this relationship, the groups used the line of best fit formula to determine how many rubber bands would be needed in order to drop the doll from a known height and get the closest to the ground without touching it. One group completed this lab and was able to get there doll to get as close as 19 inches from the ground after dropping the Barbie from a height of 280.24 inches in the air.
The Barbie Bungee lab was conducted in order to find the association between the amount of rubber bands and the distance the Barbie bungeed. Before performing the final experiment, the group conducted an initial investigation to get data that could be analyzed to examine the comparison from the amount of rubber bands to the length Barbie was able to bungee. In the investigation rubber bands would gradually be added one by one starting at two rubber bands. Each time a rubber band was added, three trial bungees were done and the lengths the barbie dropped were recorded. Using data collected from our background investigation, the group used excel to create a sheet displaying the data in a table, a graph showing the correlation constant, the line of best fit. The line of best fit was in slope-intercept form (y=mx+b) where y represents the length of the trial average; m represents the slope
