- The lower bound,Q1 andQ2 all seem to be relatively close together.Q3 seems to be stretched a little to the right
and the upper bound is significantly stretched to the right. - The bar chart has 5 categories representing each of the five periods. Within each category there are bands of
different colors. Each band represents the number of times an individual student was tardy. For periods 5 and
periods 7 there seem to be fewer students who were tardy more often. In period 2 there seems to be more students
tardy a handful of times each.
