Dr. Paulus studies the creative process and brainstorming. He conducted a study comparing the creative performance of math and communications students. Math students and Communications students were given a divergent thinking task (a standard measure of creativity) and their performance was measured (high scores representing greater support creativity). Using the data provided, test the difference between the means (assume a two-tailed t-test) and answer the questions below:
Math Students
N= 26
Mean = 5.3
Standard Deviation = 1.7
Communications Students
N= 36
Mean = 6.5
Standard Deviation = 1.4
What’s the degree of freedom and are the results significant at the .05 level ?
