Random Dotplot, v.1.1

Inspired by Craig Winske's sketch http://www.geogebratube.org/material/show/id/100672, with suggestions from Jon Hasenbank. Modification of this sketch, http://www.geogebratube.org/material/show/id/101324. New features are calculation of the median absolute deviation, and allowing you to name the mean and standard deviation of the normal population. Using uniform or random distribution, this creates random integer value data and displays it in a dot plot. How might you use this for teaching? What should students notice or be able to find looking at this data?
