Simpson’s paradox example with recent US dataset

Daróczi Gergely — Wed, 31 Jul 2013 12:15:12 +0000

Since 2000, the median US wage has risen about 1%, adjusted for inflation.

But over the same period, the median wage for:

high school dropouts,

high school graduates with no college education,

people with some college education, and

people with Bachelor’s or higher degrees

have all decreased. In other words, within every educational subgroup, the median wage is lower now than it was in 2000.
