Document Summary
Guided notes associated with the lecture videos for the 1st half of chapter 2. Connecting chapter 2 to our current knowledge of statistics. In chapter 1 we used graphical displays to summarize data. We will now shift to describing data numerically. We will describe centers and spreads of distributions; and contrast which are most appropriate in different situations. Many of the statistics are familiar to you from your k-12 years. For context, we"ll consider that a friend of yours from high school, cannot recall the difference between the mean and the median. Based upon what your current knowledge of means and medians. We will see how these measures are useful in describing both the center and shape of a dataset. 2. 1 measuring center: the mean and the median. The mean dividing by the number of observations. It is considered the balance point of the distribution. The mathematical notation for the mean is x.
