Experiment 6: Probability General Chemistry I and II Lab Manual Dakota State University Page 91 of 232 Experiment 6: Probability Purpose: To generate a fair quantity of numbers for students to practice certain statistical tests and methods. Porpoise: A friendly aquatic animal. Background: None Introduction: There is an old joke, regarding a famous concert hall, Carnegie Hall, in which only the most talented musicians in the world are invited to play. It goes like this; “How do I get to Carnegie Hall?” “Practice, practice, practice.” And then there would be huge laughter. That’s the idea behind today’s experiment. Sure, you can practice on the homework problems, but then I would be forced to think up a real experiment. So, we’re doing this instead. You will be generating your own data for statistical analysis. The concept is to have one data set that should be completely random, one data set that should not be random but should, none the less, contain a good amount of human error, and one data set that should provide a linear relationship,

Unformatted text preview: but with fairly good random error as well. I would like you to perform the statistical analysis using Excel, both by putting in your own formulae (from our textbook), and from using Excel’s built in functions. I also highly encourage you to repeat these calculations using your hand-held calculator as practice for the exam, since you probably won’t have Excel available to you then. Good luck! Procedure: CAUTION! Wear safety goggles and aprons throughout the entire experiment! Unless you don’t want to. A dicey problem: You will find dice in the lab. Throw this dice 100 times, keeping track of the sum total of each throw. Return to Middle School: If a paper football does not exist, make one. On the floor, use a piece of tape to denote the “touchdown”. From the other side of the lab, slide the paper football 100 times; record the distance from “scoring” for each throw. Remember to keep track of the...
