Discussion
Using the attached data (i.e., "job satisfaction" and "practice"), perform one analysis (i.e., Part A or B) using a dependent (or paired) samples t-test and the other (i.e., Part A or B) using the independent samples t-test. Determine appropriate test for each relationship, and then proceed with your analyses. (To be clear, you are required to perform TWO t-tests in this submission.)
Part A
Thirty teachers at ACE Charter School were given a 20% raise in their salary in August of 2015. How was their job satisfaction ("0" = very unsatisfied to "50" = very satisfied) affected as a result? (Note: You can make causal inferences in this analysis.)
• What is the research question? (Use "difference" language as we are no longer talking about "relationship" among variables but differences between groups.)
• What is the null hypothesis?
• What is the research hypothesis? (Directional)
• Basic descriptive analysis appropriate for the variables used (e.g., mean, median, range, SD, etc.) in a paragraph form. (Don't just include a number of SPSS tables and not talk about it.)
• State the rationale for applying either independent or dependent t-test in this investigation using appropriate readings and resources in Module 6. (Please cite specific references.)
• Write out the results in an APA format.
• Include appropriate tables from the SPSS output used in your analyses.
Part B
Using a sample of 575 participants, compare the average years of education (variable name = "educ") between men and women in River Forest, IL . (Note: Avoid causal inferences here, and just talk about the differences between men and women in the analysis.)
• What is the research question? (Use "difference" language as we are no longer talking about "relationship" among variables but differences between groups.)
• What is the null hypothesis?
• What is the research hypothesis? (Non-Directional)
• Basic descriptive analysis appropriate for the variables used (e.g., mean, median, range, SD, etc.) in a paragraph form. (Don't just include a number of SPSS tables and not talk about it.)
• State the rationale for applying either independent or dependent t-test for in this investigation using appropriate readings and resources in Module 6. (Cite specific references.)
• Write out the results in an APA format.
• Include appropriate tables from the SPSS output used in your analyses.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
