Data Presentation 1. (5pts). Which of the following points about the data presentation lecture and chapter are true? MTF A) The scale of presentation: class responded differently to graphs of the same data that merely used different scales on the axes B) Some methods of presentation have been found to cause little bias in a person’s response. One example is that the scale used to provide multiple choice options for a question does not affect the response as long as the correct answer is included in the options. C) We considered two ways of presenting data that allow one to calculate a false positive rate in a drug test . The approach using conditional probability was more difficult to understand than the approach using natural frequencies. D) When describing the benefit of a drug, use of relative frequencies (e.g., 50%) was said to be more favorable than absolute frequencies (e.g., 2 in 1000) for convincing people to use the drug. Language of evaluation 2. (5pts) The following options pertain to the concept of model falsifiability. Which are true? MTF A) We briefly discussed a newspaper article on pet psychics. It was suggested that many of the claims of a pet psychic (about how the pet feels) are not falsifiable. B) If a model is not falsifiable, it means the same as data being irrelevant to the model. C) If a model is not falsifiable, no data can possibly be gathered that might refute the model. D) As shown in the video, psychic phenomena applied to humans (e.g., horoscopes, palm reading) cannot be subjected to evidence-based (scientific) evaluation – they lie outside the scientific method. 3-6. (3 pts each) Use the 4 options listed below to answer the next four questions. MTF for each A) The data are irrelevant to the model B) The data are inconsistent with the model C) The data support the model D) The data prove the model 3) Which options mean that the data could not refute the model no matter how they turned out? A B C D 4) Which options mean that the data could possibly have refuted the model but did not? A B C D 5) Of 100 models that the data might have refuted, the data refute all but one. What do we say about the relationship of the data to the one model that was not refuted? A B C D 6) Which options mean that the data refute the model? A B C D Correlations & Causation

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
