1.5 - Summarizing One Quantitative Variable

We will first talk about descriptive measures of quantitative data. The most important characteristic of a data set, central tendency, will be given. After that, a few descriptive measures of the other important characteristic of a data set, the measure of variability, will be discussed. This lesson will be concluded by a discussion of plots, which are simple graphs that show the central location, variability, symmetry, and outliers very clearly.
