[br]Drag the points to see how the mean, median, and root mean square (RMS) react.[br]Things to notice:[br][list][*]The mean and RMS are sensitive. They adapt to every x value change. [/*][*]The median is resistant. It only responds to changes in the middle x values.[/*][*]The RMS treats negative x-values as if they were positive.
