MATH108X - Trend Lines Case Study #1 #2 #3 #4 #5 Project Goal : To learn how trend lines can be used as a powerful tool in the Quantitative Reasoning Process. Begin by selecting a scenario that will use a scatterplot and trend line as the mathematical tool to make an informed decision. (Remember that we are looking for numerical/quantitative data where the scatterplot and trendline would show the relationship of an input and output variable). You may use the examples as a guide, but it is preferred that you use creativity to choose a scenario that is useful in your real world. As best you can, list the key variables and assumptions you will be making in order to eventually make your informed decision. You should have exactly two key variables, an input variable and an output variable. Collect data (at least 15 points), report your source(s), make a scatterplot, and fit an appropriate trend line to the data in order to make your informed decision. Be sure to state which trendline best fits your data using the box provided and record your equation. Make an informed decision using your scatterplot and trend line you created in Step 3. Write about your decision. Include a prediction you made using the trendline equation. Ensure your decision is well supported by your data and trend line. Share your idea and data with at least two other people. Get feedback from them and mprove your project accordingly. Complete the Quantitative Reasoning Process by writing a short paragraph that details any changes you made after your reviewers helped you to evaluate your data and reasoning.
