    Students begin by exploring univariate data. They will examine a histogram and a box plot of the commute time for workers in different US cities. From the data displays students will determine the mean and median.

    Students will also explore bivariate data. From a survey on teachers’ ages versus the number of years they have been teaching, they will find a manual line of best fit and then calculate a linear regression.
