Goodness of Fit {Adapted from “The Practice of Statistics, 2e by Yates, Moore, Starnes} This activity can be used to introduce the concept of Chi-square distributions and the “Goodness of Fit” test. Using a bag of m&m’s, you will compare the observed color counts to the expected color counts as noted by the m&m/Mars company.

    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.
