Simpson's paradox

Postby Joseph Malkevitch » Sat Oct 28, 2017 3:56 pm

Dear Colleagues,

Simpson's paradox calls attention to the fact that a "trend" when looking at a whole group may not hold for subgroups of the whole group - in fact one may see "opposite" behavior in the two subgroups that make up a group from what one sees in the group. Examples of this phenomenon are useful in settings in lower grades where students are learning about percentages, fractions, and graphing data.

Here is the wiki article about this phenomenon

and a recent look at examples involving "human behavior."
