SPSS Week 6 Imagine a researcher is interested in the relationships among teachers' self-esteem and productivity. A randomly selected sample of 40 teachers completed a questionnaire including a number of demographic questions as well as measures to assess their self-esteem and productivity. Below are the demographic data and participants' responses for the self-esteem measure (100-point scale) and the productivity measure (50-point scale). Use these data to answer the questions below (these data have already been entered in a SPSS file; see the note below the data table). Gender (M = male, F = female) M M F M F F F F M M F F F F M M F M F M M M F F M F M Self-esteem scores (ScoreOne) 64 68 74 75 76 79 80 82 68 70 74 76 78 79 82 85 71 73 75 77 78 80 83 86 73 74 77 Productivity Scores (ProdOne) 25 28 36 38 34 36 40 41 22 38 39 34 38 37 45 46 30 34 33 36 38 42 46 49 37 38 32 M F M F F F M F F M M F F 77 78 81 84 87 77 71 75 76 79 83 89 91 35 36 45 49 48 36 33 34 36 38 48 48 49 Download the SPSS data set: teachersurvey.sav. Not all of the variables in that SPSS file will be used for this assignment. In this SPSS assignment, use the tools learned in this course thus far, with an emphasis on the tools acquired in Gravetter and Wallnau (2013) Chapters 9 and 10 and George and Mallery (2014) Chapter 11. 1.) There are three main assumptions needing to be satisfied before using the independent-samples t-test for testing differences between the genders. Use SPSS to generate the output needed to test the assumptions. Please discuss each one and explain whether each has been met using SPSS output as needed to include histograms, plots, and Levene's test. Keep in mind if the population value is unknown, it is permissible to infer from sample values. Regardless of sample size, test whether these assumptions are met. 2.) Please produce an SPSS output for an independent-samples t-test comparing male and female scores on self-esteem. a.) What are the null and alternative hypotheses? b.) What is the value of Cohen's d? Is it small, medium, or large? Use the following web site to calculate Cohen's d: http://www.uccs.edu/~lbecker/ c.) Report the results in APA format. d.) What might be concluded from this hypothetical study (males vs. female selfesteem test)? In this conclusions, please consider possible limitations of the study as well as recommendations for future research. 3.) The researcher conducted an analysis for her employer and found a t-value just short of the critical region using a two-tailed test. She has to fail to reject the null hypothesis, but fears this may affect her research funding and possibly her employment. Then she remembers one-tailed tests have larger critical regions. Is it ethical for to change her original hypothesis to a one-tailed test? Why or why not
