Statistical analysis of quantitative data is … Explore what probability means and why it's useful. That is, you must establish or adopt a system of assigning values, most often numbers, to the objects or concepts that are central to the problem under study. Measures of central value such as the mean or median must be coupled with measures of data dispersion (e.g., average distance from the mean) to indicate how well the central value characterizes the data as a whole.

This unit covers the basics to statistics, from basic terms and definitions in Chapter 1, to the location and spread of a distribution of data in Chapters 4 and 5, estimating population parameters from samples in Chapter 7, and calculating probabilities in Chapter 8. This initial part of the report introduces the basic elements in (statistical) decision theory and reviews some of the basic concepts of both frequentist statistics and Bayesian analysis. We would expect the proportion of the 1,200 voters in the survey who are in favor to be close to the proportion of all voters who are in favor, but this need not be true. Statisticians try to interpret and communicate the results to others.
