    • Describe the basic equation for statistical models (outcome=model + error)
    • Describe different measures of central tendency and dispersion, how they are computed, and which are appropriate under what circumstance.

    One of the fundamental activities in statistics is creating models that can summarize data using a small set of numbers, thus providing a compact description of the data. In this chapter we will discuss the concept of a statistical model and how it can be used to describe data.
