What do the skewness and kurtosis values tell you about whether the data satisfy the assumption of normality?Дescriptive StatisticsNMinimumMaximumMeanStd. Run Descriptive Statistics on the dependent variable data. Did you find any errors that the researcher made when setting up the SPSS data file (Remember to check the variable view)?В If so, what did you find? How did you correct it?No errors are observed in setting up of the data file the data is coded and appropriately entered4. The twoвЂђway ANOVA tests three hypotheses: the main effects for each of the two factors and the interaction effect3. Why is a two-way between-subjects factorial ANOVA the correct statistic to use for this research design?Then twoвЂђway between subjects ANOVA is used to analyze the results of a between subjects factorial design with two independent variables (factors). What are the two independent variables in this study?В What is the dependent variable? Independent variable:Study environment SexДќependent variable: Academic performance2.

There is no separate answer sheet/guide to use while doing this assignment.1. NOTE: Helpful hints are provided here for you to use while answering these questions. The GPA improvement score was used to measure academic performance.Directions:Using the SPSS 2 Г— 3 ANOVA data file for Module 4 (located in Topic Materials), answer the following questions. The difference was each students GPA Improvement score. A change score was computed for each student: each students spring midterm GPA was subtracted from his or her GPA for the preceding fall semester. At the end of the 7-week research period, mid-term GPA was computed for each student. The students could ONLY study in the environment to which they were assigned during the research period. During the first half of the spring semester, 120 male students and 120 female students in grade 10 at a public high school in a large metropolitan area in the southwestern region of the United States were randomly assigned to one of three study environment: study in front of the TV, at the library, or in the food court. In addition, this study investigates whether sex of student 'moderates' the effect of study environment on academic performance (that is, do males and females differ in how much benefit they get from studying in certain environments). PSY 870: Module 4 Problem Set 2 Г— 3 Between s Factorial ANOVA: Study Environments by Gender This study investigates whether study environment affects academic performance.
