MUST USE SPSS PLEASE! A researcher wants to examine the relationship between a freshman’s motivation and GPA after their first semester enrolled in a university. The researcher sent out an initial survey to measure the motivation of a small group of incoming students at the beginning of the semester and a follow up questionnaire examining their GPA at the end of the semester. Use the following data the researcher gathered to complete each step of the assignment instructions. What would be the predicted first semester GPA of a student who attained a motivational score of 4.5 at the beginning of the semester? Motivation GPA 1 3.4 6 3.4 2 2.5 7 3.1 5 2.8 4 2.6 3 2.1 1 1.6 8 3.1 6 2.6 5 3.2 6 3.1 5 3.2 5 2.7 6 2.8 6 2.6 7 2.5 7 2.8 2 1.8 9 3.7 Use the SPSS program to calculate the correlation and create a scatterplot. Provide the appropriate output given by the program. Describe this relationship (both in strength and direction and in layman’s terms). Determine if these variables are truly related, or could there be a third variable at play? Calculate the regression equation using SPSS-Include the regression test output. Use that regression equation to calculate the prediction described in each problem.
