http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1992
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1992November 24, 2009 Activity webinar presented by Carl Lee, Central Michigan University, and hosted by Leigh Slauson, Capital University. This webinar introduces a real-time online hands-on activity database for teaching introductory statistics. One particular activity, "How well can hand size predict height?", is used to engage students with a real-time activity in order to learn bivariate relationships. Various other activities can be found at stat.cst.cmich.edu/statact. The real-time database approach speeds up the process of data gathering and shifts the focus in order to engage students in the process of data production and statistical investigation.Wed, 9 Dec 2009 10:31:17 -0500What Does It Take to Heat a New Room?
