S INGLE -S AMPLE T -T ESTS AND P AIRED -S AMPLES T -T ESTS

I need help with this please! attach is the instructions

PSYC 355 SPSS H OMEWORK 1 I NSTRUCTIONS : S INGLE -S AMPLE T -T ESTS AND P AIRED -S AMPLES T -T ESTS When submitting this file, be sure the filename includes your full name, course, and section. Example: HW1_JohnDoe_355B03 Part 1: Note that for all problems in this course, the standard cut-off for a test of significance will be p < .05 unless otherwise noted in the problem. 1. Single-Sample t -Test (based on Green & Salkind: Lesson 22 – Exercises 1–4, but follow the instructions below instead) Open the Lesson 22 Exercise File found in Blackboard Course content (under Syllabus and Assignment Instructions>Assignment Instructions>SPSS Homework 1>SPSS Homework 1 Files>Mod1_Lesson 22 Exercise File 1). Always use the Blackboard files instead of the files on the Green and Salkind website, as some files have been modified for the purposes of this course. 1. A total score variable is included in the data file in Blackboard (“tot_score”), so you do not have to compute it. Use this variable as your dependent variable. 2. The test value for the single-sample t -test is 2 (1/4 of 8, or the score which a student would achieve by chance). Use 2 as the test value when running the analysis for this exercise. 3. Conduct a single-sample t -test on the total score variable. Paste the output into your Word document and type in the answers to the following questions underneath the output: (2 pts for output) a. Mean algebra score (2 pts) b. t -test value (the result of the t -test, not the “test value” which is already given) (2 pts) c. p value (significance) of the test (2 pts) 4. Write a current APA-style Results section based on your analysis. All homework Results sections must follow the example given in the SPSS tutorials and the Course Content document “Writing Results of Statistical Tests in Current APA Format” (note: you do not have to refer to a figure). Remember to include a decision about the null hypothesis. (2 pts) 5. Create a histogram that demonstrates the distribution of scores. Be sure to correctly label the X and Y axes and give your graph a title. (2 pts) 2. Green & Salkind: Lesson 23 – Exercises 6–8: (Lesson 23 Exercise File 1) The following helpful tips are numbered to correspond with the exercise number to which they refer within the Green & Salkind text: 6. Instead of identifying these values on your output, as the text states, write them into your Word file as written answers for #6 a, b, c, and d. (output = 2 pts; a–d = 2 pts each) Page 1 of 3
