PSY203: Design & Statistical Analysis Dr. Crawford Project 2: t-tests The purpose of this project is to check your proficiency with identifying the correct statistical test to use based on the research design, organizing and analyzing data in SPSS, and reporting your findings in APA style. Answer all three questions on the following pages. Data analyses (Data set .sav and output .spv files) are due. The Word document with APA style descriptions and any necessary figures is due Question 1: Christina Finello is campaigning as a Democrat for a seat in Congress in Bucks County, PA. She wonders if the size of a lawn sign affects voters’ willingness to display the sign on their property. Her campaign staff sends smaller signs to registered Democrats in one half of the neighborhoods in Finello’s district, and larger signs to the other half of the neighborhoods. Two weeks later, her staff drives through the neighborhoods to determine what percentage of sign recipients in each neighborhood decided to display their lawn sign. The percentage of registered Democrats in each neighborhood who displayed their law signs is as follows: Large Sign Small Sign 34 41 41 44 30 36 32 38 28 29 31 47 40 49 27 39 36 43 22   What do you conclude about the effect of the size of the lawn sign on decision to display it? Present the results in APA style. Be sure to report effect size. Create a figure displaying the results. Question 2: Below are the math test scores in a fourth grade class at Hopewell Elementary School. The NJ statewide average on this same test for all fourth graders is 77. The scores for this particular fourth grade class are as follows: 72 80 82 91 81 83 74 92 79 83 80 82 94 70 82 75 74 76 89 78 90 82 92 72 73 81 77 67 75 68 What do you conclude about this particular fourth grade classes’ math scores, relative to the NJ state average?
