Statistics 101: Group Project Now that you know the principles of good experimental design, you are going to have the opportunity to design your own experiment, collect data, analyze the data, and write about your findings. This project will give you firsthand experience in using the ideas presented so far in STAT 101: you will have to use the techniques you've studied to analyze the data and draw conclusions about your findings. For this project, you will work in groups of four or five people. All members of your group will be equally responsible for the project, and all members will receive the same grade on this assignment. Your experiment must develop and answer a question about one of the following: Strength of paper towels Flight of paper airplanes or paper helicopters Quality of microwave popcorn Time to boil water Distance a golf ball rolls Quality of batteries Research Question and Conjecture. First, decide what research question you will ask, what you conjecture as the answer to that question, and what explanatory and response variables you will collect to address the question. In order to use the analysis techniques you have learned in class, you must make both the explanatory and response variables quantitative . Document these choices in the introductory section of your report where you explain the purpose of your research and its relevance for your audience (classmates). For that audience to understand your later data analysis, you must begin with a direct, specific research question; for example, “Our research question is to look at the relationship between the height you drop a tennis ball and the number of bounces that occur before it comes to rest. We conjecture that if you drop a tennis ball from higher up, it will take more bounces before it comes to rest.” Note in this example that both variables, height and number of bounces, are clearly quantitative.
