Displaying and Describing Univariate Data
Univariate data are quantitative if the individual observations are numerical values. In such contexts numerical operations generally have meaning, and the variables have units. In these lessons, students investigate measures of center and spread including standard deviation and the mean as the center of mass. Students identify and analyze important characteristics of graphs of data, consider how different representations of the same data are related, and create and describe dotplots, boxplots and histograms.
