Glendale Community College T Test Practicing Statistical Analysis
Part 1Can a student mentor improve the grades of freshman high school students? Complete parts A-D. You want to determine if pairing an incoming freshman with a sophomore in a mentor–mentee relationship will enhance the freshman’s overall grade. You recruit sophomores who are willing to mentor students in their majors for their first terms. You then recruit freshmen who are interested in having mentors. Freshmen who apply to this program will be assigned to the mentor group (and will be given mentors) or to the control group (no mentor) on an alternating basis. Those in the mentor group are to meet their mentors in person once a week at a time of their choosing. All freshmen, in both groups, agree to submit their transcripts at the conclusion of the term.CodebookVariable: groupDefinition: Mentor group assignmentType: Categorical (1 = No mentor, 2 = In-person mentor)Variable: gradeDefinition: Student’s overall gradeType: Continuous (0–100)A.Write the hypotheses.B. Run each criterion of the pretest checklist (normality, homogeneity of variance, and n) and discuss your findings.C.Run the t test and document your findings (ns, means, and significance [p value]).D.Write an abstract up to 200 words detailing a summary of the study, the t test results, hypothesis resolution, and implications of your findings.Part 2Are men and women of significantly different ages when they become parents?From the General Social Survey (GSS) 2018 database (https://gssdataexplorer.norc.org/ (Links to an external site.)), you will analyze the results of a t-test with the variables sex and agekdbrn applied to the model.You must refer to the following SPSS output information provided here, if you are to complete both parts of the assignment, Chapter 5 Practice Exercises Data Output Report.htmWrite the hypothesesAssess each criterion of the pretest checklist (normality, homogeneity of variance, and n). Interpret the outcome. In up to 200 words, write a detailed summary and interpretation of the t test results, state your hypothesis resolution, and discuss the implications of the findings. -To receive full credit for this assignment, you must submit a written abstract that contains your full written analysis/interpretation of the data as per both outcomes of each t-test.
