Biking may be an outlier. Using data from 10 states on the number of people reporting they bike to work, pupils calculate the measures of center. Scholars determine the range and interquartile range and find which provides a better description of the data. Learners then create box plots from the statistics calculated and analyze it specifically looking for any outliers.
