6th Grade Data Analysis and Statistics Resources

Comparing Mean, Median, and Mode

Enter data in a list (or click RANDOMIZE), then see it displayed as a lineplot and/or boxplot. Select which of {Mean, Median, Mode} you want shown for each data set. Possible teaching moves include:

• Make predictions about where each measure of center will fall

• Justify why the mean would be above or below the median

• Look for the connections between the lineplot and boxplot

Draw the Box Plot to Match the Dot Plot

This tool lets students practice drawing box plots from dot plots. Consider what a box plot DOES before getting into that 5 number summary stuff. "What are you noticing about how these overlap?"

Resistance of Mean and Median

A tool designed to investigating the notion of resistance in measures of center. A randomly generated dot plot is drawn (size determined by user). Drag the blue point to see how the mean and median are affected.
