Activity Name Activity Description
PieChart Students view piecharts. Parameters: Number of sectors, size of sector as a percent.
Histogram Students view histograms for either given or user-specified data sets and can adjust class interval size. Discussion can focus on how interval size can influence interpretation of the graph.
Stem and Leaf Plotter Students input a data set and view and associated stem-and-leaf plots provided by the applet. Students can also use the applet to verify their own calculations for mean, median and mode of the data set.
Plop It! Students use a point-and-click interface to build a histogram of number values. The applet calculates and displays updated values for mean, median, and mode as numbers are added to the plot.
