GCH 335 Module 7 1. a. The mean for the pretest is 32.8000. b. The mean for the posttest is 34.0000. c. The value of t is –1.385. d. The associated probability is .200. e. .200 is greater than .05, the difference between means is not statistically significant at the .05 level. f. The mean scores increased from 32.8000 ( sd = 4.61399) on the pretest to 34.0000 ( sd = 5.05525) on the posttest. Note that the probability of .200 is greater than .05, so the difference is not statistically significant. Also, note that although the value of t is negative, it has no bearing on significance. Significance is determined solely by the probability (the value of p ). 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
