Module 6 Assignment 1. Incarceration rates vary from state to state. We must remember that correlation is not causation but we can ask: \"what state level factors might be associated with the state incarceration rate? I drew a sample of 17 states using a systematic random sampling method (Chapter 7). Using data from the Bureau of Justice Statistics, the Kaiser Foundation and the FBI, I gathered published data on: Incarceration Rate per 100,000 Adults (2013) Median State Income (2010-2013) Total Crime Rate from Uniform Crime Reports (Violent crime and Property crime) a) Before you look at the data (on the next page), state an appropriate null and research hypothesis concerning the relationship between Incarceration Rate and each of the two independent variables. b) Which of these predicted relationships do you expect to be strongest? Why? For each of these relationships, calculate: c) The prediction equation (least squares line) d) The Coefficient of Determination e) Pearson's r f) Would multiple regression be a useful statistical tool for further analysis of these data? Why or why not? You do not need to do any calculations.
