Webinar: Fighting cancer with raspberries: demonstrating the value of random assignment

May 26, 2009 Activity webinar presented by Dennis Pearl, The Ohio State Unversity, and hosted by Leigh Slauson, Otterbein College. This webinar describes a computer lab activity using the Flash-based applet at www.causeweb.org/mouse_experiment to teach key principles regarding the value of random assignment. These include:
1) how it helps to eliminate bias when compared with a haphazard assignment process,
2) how it leads to a consistent pattern of results when repeated, and
3) how it makes the question of statistical significance interesting since differences between groups are either from treatment or by the luck of the draw.

In this webinar, the activity is demonstrated along with a discussion of goals, context, background materials, class handouts, and assessments.
