PSYC 515 SPSS M1 REVIEW SPSS WORKSHEET INSTRUCTIONS Answered 2023. HOMEWORK: REVIEW SPSS WORKSHEET INSTRUCTIONS OVERVIEW This worksheet is designed to assess your ability to perform, interpret, report, and graphically represent the following statistical tests using SPSS and standard reporting conventions as covered in this course: correlations, regression, independent samples t tests, and correlated groups t tests. These are standard tests in our field and are foundational to the more sophisticated research designs. Knowledge of these tests provide fundamental skills to critically evaluating and producing research in one’s field. INSTRUCTIONS Be sure you have reviewed this module’s assigned readings and presentations before completing this assignment. This includes using ensuring the homework is completed and submitted according to the instructions, SPSS output and images are legible and relevant, and that basic college level writing skills (e.g., grammar) are used in the write-ups. Answers should be placed where indicated (e.g., “ANSWER”). Note: all questions must be attempted to be eligible for full credit. Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p.001). Also, remember that we divide the p-value in half when reporting one-tailed tests with 1 – 2 groups. Also – remember to check your graphs! You often have to ADD the y – axis title. • Submit the file as a WORD document (.doc or .docx). Make sure the filename of your submission includes your full name, course and section. o Example: SPSS1_JohnDoe_515B01 Scenario 1 A major university would like to improve its tarnished image following a large on-campus scandal. Its marketing department develops a short television commercial and tests it on a sample of n = 10, the first ten students who entered a housing commons area who agreed to participate. Attitudes about the university are measured with a short questionnaire, both before and after viewing the commercial. Attitudes were on a scale of 0 – 20, which higher numbers reflecting better attitudes. Use the provided data to examine whether the commercial improved the university’s image. The data are as follows: Person X1 (before) X2 (after) A 15 15 B 11 13 C 10 18 D 11 12 E 14 16 F 10 10 G 11 19 H 10 20 I 12 13 J 15 18 1. In this specific scenario, what is the independent variable? Is it between or within subjects? How many levels does it have, and what are they? ANSWER The independent variable is the commercial variable that is being displayed. It is considered within subjects because the same indivduals were tested before and afer watching the commercial to determine the attitude scale. It contains two levels because it measures the attitude before and after the TV commercial. 2. In this specific scenario, what is the dependent variable? What is its scale of measurement (nominal, ordinal, or scale)? ANSWERThe depedendent variable is the attitude scale being measured from 0 to 20 before and after the TV commercial. The scale of measurement is scale. 3. Paste all relevant statistical output in the space provided below: ANSWER
