Statistics Data Analysis - SPSS required

Comparison of Means

Submit one Word document for this assignment (copy and paste SPSS output into the Word document).

1. Paired Samples t test: For this assignment, you are interested in finding out whether participation in a creative writing course results in increased scores on a creativity assessment.

a. Use the data file “Unit7.sav” located in Unit VII. In this file, “Participant” is the numeric student identifier, “CreativityPre” contains creativity pre-test scores, and “CreativityPost” contains creativity post-test scores. Atotal of 40 students completed the pre-test, took the creativity course, and then took the post-test. (0 pts.)

b. Exploratory Data Analysis: Perform exploratory data analysis on CreativityPre and CreativityPost, then copy and paste the output into the Word document. (15 pts.)

c. Report: Using SPSS, calculate the mean and standard deviation of these two variables and report them in 1 -2 sentences. (5 pts.)

d. Chart/graph: Construct an appropriate chart/graph that displays the relevant information for these two variables. (20 pts.)

e. Hypotheses: Write the null and alternative hypotheses used to test the question above (i.e., whether

participation in the course affects writing scores). (10 pts.)

2. Comparison of Means

a. T-Test: Perform a paired samples t test to assess your hypotheses above (note that many versions of SPSS use the term “paired samples t test” rather than “dependent t test;” the test itself is the same). Copy and paste the output into the Word document. (20 pts.)

b. Results: Write one or two paragraphs that describe the dataset, give(s) your hypothesis, and present(s) the results of the paired samples t test. Be sure that your writing conforms to APA style. (20 pts.)
