PSYC 3110 Scientific Inquiry in Psychology Homework 5 Instructions Answer the following short-answer questions. All answers should be in complete sentences and free from proofreading errors. You should not need more than a paragraph to answer each question. Remember that more isn’t necessarily better. Do not include the homework questions in your submission. Just give the question number and your answer. All sentences and ideas are assumed to be your own unless you cite your source. Using someone else’s work without attribution is plagiarism and will result in an F in the course. Please note that artificial intelligence is not permitted for this assignment. See the “Artificial Intelligence” section for more details. Questions 1. Use the scatterplot shown in Figure 1 to answer this question. a. There are some points in the top left of Figure 1. Did participants in the top left of the graph score high or low on x? Did they score high or low on y? b. There are some points in the bottom right of Figure 1. Did participants in the bottom right of the graph score high or low on x? Did they score high or low on y? 1 Figure 1: -2 -1 0 y 1 2 Question 1 Scatterplot -2 -1 0 1 2 x c. Does Figure 1 depict a positive, negative, zero, or curvilinear relationship between x and y? How do you know? d. Consider the scatterplot shown in Figure 3. Does Figure 1 depict a stronger or weaker correlation than Figure 3? Explain. 2. Use the scatterplot shown in Figure 2 to answer this question. a. There are some points in the bottom left of Figure 2. Did participants in the bottom left of the graph score high or low on x? Did they score high or low on y? b. There are some points in the top right of Figure 2. Did participants in the top right of the graph score high or low on x? Did they score high or low on y? c. Does Figure 2 depict a positive, negative, zero, or curvilinear relationship between x and y? How do you know? 2 Figure 2: -2 -1 0 y 1 2 Question 2 Scatterplot -2 -1 0 1 2 x d. Consider the scatterplot shown in Figure 3. Does Figure 2 depict a stronger or weaker correlation than Figure 3? Explain. 3. Spencer has just developed a new measure of emotional intelligence. Because his measure is new, he needs to ensure its reliability. Spencer assesses its test-retest reliability by administering the survey to 19 undergraduate students. Every student takes the survey twice. His results are plotted in Figure 4. Does Spencer’s measure of emotional intelligence have test-retest reliability? Explain. 4. Can a measure be reliable but not valid? Explain. 5. Can a measure be valid but not reliable? Explain. A Note on Plagiarism You are assumed to be familiar with CSUB’s policy on academic integrity. 3 Figure 3: -2 -1 y 0 1 2 Comparison (Baseline) Scatterplot -3 -2 -1 0 1 2 x Figure 4: 0 -2 -4 Time 2 Scores 2 Test-Retest Reliability of Spencer's Emotional-Intelligence Survey -4 -3 -2 -1 0 Time 1 Scores 4 1 2 Intentional or accidental violation of the policy constitutes academic dishonesty (cheating) and will result in an F in the course. Please never cheat—it is not worth it! Artificial Intelligence You are explicitly prohibited from using artificial intelligence, including tools like ChatGPT, to complete this assignment. Engaging in such practices would not only constitute academic dishonesty but also have severe academic consequences, including receiving a failing grade (F) for the course, being referred to the Dean of Students Office, and having a permanent mark attached to your academic record. While I cannot guarantee that I will detect every use of artificial intelligence, I urge you to consider the long-term effects and ethical implications of dishonest behavior. Here are some compelling reasons why utilizing artificial intelligence in this course is counterproductive: • Learning opportunity: The homework assignments provide a low-stakes opportunity for you to identify your strengths and areas for improvement. Relying on artificial intelligence deprives you of this opportunity, leading to inadequate preparation for more significant assessments such as in-class quizzes, midterms, activities, and the final exam. • Inaccuracies: Artificial-intelligence tools may not provide accurate solutions to all of the complex problems covered in this course. Repetitive errors resembling artificial-intelligence-generated content will be con5 sidered a violation of CSUB’s policy on academic integrity. • Synonyms and terminology: Artificial intelligence often uses various synonyms for research-methods terms. Using terminology not covered in the course material may indicate artificial-intelligence use or unauthorized external sources (remember that all external sources utilized must be appropriately cited). These guidelines sound harsh, although that is not my intention. I am committed to your education: I sincerely want you to gain the skills required by this class (and which you will need for your upper-division psychology courses). To that end, the ban on artificial intelligence is necessary. If you have any questions, please do not hesitate to get in touch.

Because I am blind, there are limitations imposed on me by the screen-reading software I use. Pictures are completely inaccessible, so do not write your answers by hand and take a picture. Instead, type your answers in a word processor and submit that file. The following file formats are permissible: doc, docx, rtf, txt, and pages. Note that pdf files will not be accepted. Submission Requirements This assignment must be submitted on Canvas by 11:59 P.M. on Sunday, March 10, 2024. Late submissions will not be accepted.
