Two One-Sample t-Tests in SPSS
VERVIEW
This assignment is designed to increase your statistical literacy and proficiency in conducting and interpreting the one-sample t test, as well as to assess your cumulative knowledge of SPSS work in the course. You will be completing two one-sample t tests in SPSS, using data that are
related to specific research scenarios in the behavioral sciences, such as psychology, social work, and counseling. You will also be completing three more problem sets that assess SPSS procedures learned in previous modules. Behind-the-scenes knowledge of how the one-sample t test is conducted is fundamental to being able to understand and apply research in your related field to your practice. Additionally, SPSS skills are professionally valuable, as it is one of the most commonly used statistical software packages in behavioral science settings, both academic and professional.
INSTRUCTIONS
To access the homework problems for this assignment, please download the SPSS Homework: One-Sample t-Test and Cumulative Questions Template document linked on the SPSS Homework: One-Sample t-Test and Cumulative Questions
Assignment page.
This assignment includes five problem sets that contain research scenarios and related questions: two for the one-sample t test, and three cumulative problem sets.
ALL variable names in your SPSS data files must include your initials, so that they show up in your SPSS output and graph. For example, for someone with the initials ABC creating a variable of memory scores, the variable could be named “ABC_mem_scores” or “Mem_Scores_ABC”, etc.
For each scenario, you will run an analysis in SPSS. The required product for the one- sample t test will include the SPSS output, an APA-style Results section describing the results, and the appropriate graph inserted as a Figure in current APA style.
For the cumulative problem sets, paste your SPSS output directly into the homework underneath each relevant question. Typewritten answers into the document underneath the question to which they relate.
For all t test problems, interpret results based on an alpha level of = .05.

Problem Sets 1 and 2: The One-sample t test
Problem Set 1: Research Scenario: An industrial-organizational psychologist wants to measure the effect of the Covid pandemic on the life satisfaction of nurses actively working during the pandemic. She administers the Satisfaction with Life Scale (Diener et al., 1985) to thirteen nurses during the pandemic. The population mean for nurses is m = 23.6. Using the sample data in the table below, set up your data file in SPSS and conduct a one-sample t test to determine whether this sample has a lower SLS score than the general population of nurses. Create a histogram to display the distribution of the sample’s SLS scores. Remember to put your initials within any and all variable names.
