Students extend their understanding of variability in data and of ways to describe variability in data. They calculate and interpret standard deviation. Students use distributions to describe variability, and normal distributions are introduced as a way to model data distributions that are bell-shaped and approximately symmetric. Students calculate and interpret areas under a normal curve and explore reasoning that allows them to draw conclusions based on data from statistical studies. Students use data from a random sample from a population to estimate the values of population characteristics, and they use margin of error to quantify the uncertainty associated with their estimates.
