As you have seen in earlier lessons, statisticians have visual and numerical ways of describing a set of data. Histograms are one of the most common ways to display numerical data. By looking at a histogram, we can easily see the mean and spread of the data. In this lesson, you will learn how the visual impression of a histogram is translated into curves that closely describe the data.
