5th 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

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.
