I.42 What s Next Now that we can summarize and represent data in nice ways we would like to make meaningful statements about the population that gave rise to this data. For this we need to make some assumptions, leading into the notion of a Statistical Model . In this course will focus mainly on one one type of statistical model. However, going beyond this model will not be hard given the foundational knowledge you ll develop. Important!!! All models are wrong… …but some are useful. (George E.P. Box)

    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.
