The various distributions in the reading this week and last week entail probability curves that mathematically differ according to a group of parameters. Different parameters allow for specification of the shape, scale, and location of the distribution. Discuss the role that these parameters play in establishing the characteristic form for each distribution. Consider why our text doesn't discuss the location parameter very much. Why might that be? Also, if we strip away these parameters from the various distribution formulas, what's typically left? Treat this thread as a conceptual exploration, not a detailed mathematical proof.
