1. Use the SPSS data file DataSet (Excel link below) that \ file. Suppose interested in evaluating whether the overall GPA of students differs according to student gender (Gender) and whether the student GPA has increased or decreased since the previous semester (ChangeinGPA).

a. Clearly state research questions followed by corresponding null and alternative hypotheses.

b. Test all assumptions for ANOVA and report the results. Do need to make any data transformations?

c. Conduct the ANOVA and provide a short summary of the results? Did find any interaction effects? Explain.

d. Restate findings.

Enter the following data into SPSS. The data shows final grades earned by 48 students in two statistics classes taught by two professors. Each professor has taught three (3) classes; on-ground, hybrid, and online. Students were randomly assigned. The goal of the study was to find whether there are meaningful differences in student grades across different modalities. After entering the data in SPSS, answer the following questions

a. Identify the independent (factors) and dependent variables.

b. State the null and alternative hypotheses.

c. Perform a factorial ANOVA in SPSS.

d. Report results and state conclusion regarding the hypotheses.

e. Report the effect sizes (2) for any of the significant factors.

f. If applicable, conduct a post-Hoc test to determine which group means (if any) differ significantly from one another.

g. Plot the results using an appropriate graph, putting the modality on the horizontal axis.

h. Restate findings.

I could not upload the file here because too large so I can email the file if you can give me email

Note: please teach me how to answer these questions (SPSS), and process as well. really really appreciate it.
