Gage Morris gmm643 Lab Partner: Lucas Introduction: For this experiment, we are rolling steel and glass marbles down an inclined wooden board with metal pegs spaced evenly and all the way across the board. There are 21 slots at the bottom of the board labeled from -10 to 0 and 1 to 10. We will drop a total of 300 times the glass marbles and 50 times the steel marbles. Each marble dropped is recorded on paper and sorted by which slot if fell through. Then the tallied data is analyzed using graphs. There were 3 graphs made. One sample graph with the first 50 glass marble rolls out of 300 (number of tallies vs. slot number), one with probability density for 300 rolls (the 50 rolls plus 250 more rolls), and the last was

Unformatted text preview: probability density for 50 steel marble rolls. The equation used for probability density is no the sample calculations page. Also o the 300 rolls graph is the Gaussian distribution cure, and that calculation also is on the sample calculations page. The general purpose of the experiment is to see how real life results of these marble rolls compare to a curve predicted by the Gaussian distribution equation. The question: How do you think the experimental probability distribution would change if you used smaller marbles? Hypothesis: I do not think that a smaller marble will make a noticeable change in the results compared to the larger marble rolls graph....
