I think the case method works for both but for the former set, classical teaching is needed as well.</p>
<p>The case method as practiced at Harvard relies heavily on group learning. What I didn't cover is the study group. Four or five students get together every morning to discuss the cases before they go to class. Among the study group, it is usually wise to have both analytical types and qualitative types so the knowledge is shared.</p>
<p>Such group learning is easier for professional schools in which students have a wide variety of backgrounds. For say college courses, I'd recommend including handouts and exercises that students should work on before class but using the class time for case discussion rather than details of formulas.</p>
<p>I'd suggest that an intro stats class along these lines would be much more engaging and effective than the standard one. </p>Rclickhandbuch.wordpress.com commented on 'The case method and statistics'tag:typepad.com,2003:6a00d8341e992c53ef01901efc76a2970b2013-08-24T14:29:25Z2013-08-24T14:29:26ZRclickhandbuch.wordpress.comhttp://profile.typepad.com/rclickhandbuchwordpresscomI think this is a very good auxiliary method.

Here's an example: I first need to explain the concept of linear regression, before students can use it in case method style.<br />
This teaching could include the mathematics behind the parameter fitting, the R-commands necessary (my students don't know "~" for formulas before they learn lm), the formula behind Rsquared and it's interpretation, what a correlation is anyways, ... <br />
I doubt students should learn this on their own - teaching time is too valuable for that. Let's get to the application of statistical methods!</p>Kaiser commented on 'The case method and statistics'tag:typepad.com,2003:6a00d8341e992c53ef019104e3b327970c2013-08-22T02:49:10Z2013-08-24T14:45:38ZKaiserhttp://junkcharts.typepad.com/junk_chartsHi Glenn, I'm hoping that others might chime in.

There are few useful materials right now because we are far from recognizing the liberal arts component of statistics. Many textbooks contain "case studies" which are no more than long examples stripped of real-world complications, not in the style of HBS cases. <br />
If you read the article I linked to at the end, it gives a history of how the case method got adopted at Harvard, and one of the prerequisites is developing a body of suitable cases. I suspect that business cases will be hard to come by because businesses don't want to publish their data. (Also, it is hard to fake multidimensional data.) I suspect that it may be easier to develop cases from nonprofits or other arenas.</p>Glenn commented on 'The case method and statistics'tag:typepad.com,2003:6a00d8341e992c53ef0192acaca224970d2013-08-22T02:28:55Z2013-08-24T14:45:38ZGlennhttp://blog.mrwaddell.netI am interested in hearing more about this in a stats class.

I can see lessons in this style going over very well in an AP stats class in high school.</p>
