Austin Green No lab partner Hypothesis I gathered a hypothesis that the glass and steel marbles would show similar distribution. Conclusions Summary: In this lab we used the Gaussian probability distribution to study the path of a marble down a board of nails. We used both a glass marble and a steel marble to look at the differences. Specifics: The histogram from the first graph somewhat resembles the Gaussian probability curve in that it is smaller at the ends of the graph and tallest in the middle. Yet, it is not the greatest representation that I was expecting it to be. The second graph with the 300 rolls, more adequately resembled the Gaussian probability curve that I was looking for. Since the G(x) was also on this graph, it helped to show that this graph had better resembled what we were looking for in this experiment. I think it resembled the curve better because there were a lot more samples taken for this graph.

Unformatted text preview: • The third graph showed that the steel marbles were a little better at spreading out between each final position rather than how the glass marble had more in the middle than on the outsides. • Thus, I think the size of the marble did have a difference in the experiment, which proved my hypothesis to be wrong. Using the smaller radius of the steel marble increased my St. Dev. and also made my x(av) value differ much more than the other two had. Error Analysis: • Since the x(av) was not at zero than we can conclude that it wasn’t exactly random. Zero would be expected if the marble started at zero and went in a randomized pattern each time. Since none of my x(av)’s were zero than I conclude that was an error. The level that we used could have also been inaccurate, which ultimately would make our data inaccurate too....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
