Gummy Bear Experiment

3. The goal of this experiment was too see if the launcher of the gummy bear affects the distance we could launch it.

4. The factors for this experiment were the position of the gummy bear and who was the launcher. The levels of our experiment was the position being either “butt or back” and the launcher of the catapult “Gage or matt”. Our treatments were “butt matt, back matt, gage butt, or gage back” this was all depending on random names and positions drawn randomly.

5. For us to use randomization in our experiment, we had four pieces of paper with our names on it and the position of the bear in the catapult. We had our recorder randomly pick a name and the name that was drawn each time launched the gummy bear depending on the position that was chosen.

6. For our data collection we used a measurement of “tiles” and counted how many tiles the gummy bear had passed before it landed from a starting point. To collect our data we had a data table with table headings with each treatment and also the accuracy of the launcher.

7.

·         The means were Matt butt was 11.35, Matt back was 10.90, Gage butt 19.55, Gage back 18.65

·         The medians were matt butt 14.00, Matt back 11.00, Gage Butt 21.50, Gage Back 20.0.

·         The ranges are Matt butt 19, Matt back 21, Gage butt, 21, Gage back 22.

·         The mode for each is Matt butt 16, Matt back 13, Gage butt 22, Gage back no mode.

8. Based on the descriptive statistics we collected above, we can conclude which launcher and which position launches the gummy bear the furthest. The mean for the treatments involving Gage were 19.55 and 18.65, higher than Matt’s 11.35 and 10.90. This is a reoccurring trend in our descriptive statistics, like in range for example. In conclusion, Gage could launch the gummy bear further whereas Matt wasn’t as far, yet more accurate. The gummy bear being on its behind also seemed to improve distance launched.
