Statistics

This past week, we discussed different ways to represent a set of data. This included bar graphs, line graphs, stem-and-leaf plots, box-and-whisker plots, frequency distributions, histograms, frequency polygons, and measures of central tendency. Next week, we will discuss estimating results and review our statistics unit. The students will have their test on Friday over this unit.
