  1. Claims and Evidence Arguing in Science and Engineering

  2. Fair Coin Model Predictions

  3. Why argue? • Scientists argue in order to reach agreement about explanationsfor observations • Engineers argue in order to reach agreement about the best solution to a design problem

  4. What are going to argue about? • The explanation you construct to explain what you observe • Your interpretation of the data you collected • Why your design is “the best” Where else do you have to argue based on evidence?

  5. What is a claim? • A claim is a conclusion that you reached after analyzing and interpreting your data What claims could you make from our experiment?

  6. What counts as evidence? • Evidence is your interpretation of the data • It is not just the raw data itself Prediction from the model If the coin was “fair”, I would expect to see the average close to 50% and the distribution peaked there. What I observe is… which argues for/against… Evidence from data interpretation The claim is your conclusion
