Scientific Method For the following claims, observations and questions follow the steps of the scientific method. Some of these claims may be from observations (as discussed in the lecture), but some may be from the other methods of gathering information discussed (intuition, authority, tenacity). For each observation, question or claim below go through all the steps of the scientific method. Step #1 is given to you, step #5 you don’t need to do for this assignment. Scientific Method 1. Observe behavior or other phenomena. (this has been done for you and is in the form of a claim, observation or question) 2. Form a tentative answer and explanation (a hypothesis) based off the observation, question posed or claim made. You may want to restate the claim or formulate it into a question first. The hypothesis should be a positive statement that can be tested. 3. Use your hypothesis to generate a testable prediction. Explain how you would test your hypothesis. You don’t need to discuss participant selection or group formation – we’ll get into these topics later. This is a description of the type of data you would collect to test your hypothesis. 4. Evaluate the prediction by making systematic, planned observations. Although you don’t have data, tell me how you would compare your data to draw a conclusion. 5. Use the observations to support, refute, or refine the original hypothesis. You don’t need to do #5. Example: Claim (#1): People only use about 10% of their brain’s capacity. #2 Tentative explanation: Independent mental activities only require 10% of the brain at a time. Hypothesis (testable prediction): Only 10% of an individual’s brain will be active when undergoing various activities, such as reading and calculating math problems. #3 Collect data: Use fMRI to measure brain activity when an individual is at (1) rest, (2) reading, and (3) calculating a simple math problem. #4 Draw conclusions about hypothesis: (How would you look at the data to draw conclusions?) Compare brain activity in different conditions to what 10 % of total brain activity is and determine if hypothesis is correct. For the observation and questions listed below - please explain what you would do for each step of the scientific method (except #1 and 5) as I did above. Observations: 1. A lot of accidents are caused by people texting and driving. 2. Students who use their phones in class for non-school related activities do not do good on exams.
