Why do we make statistics so hard for our students?
(Warning: long and slightly wonkish) If you’re like me, you’re continually frustrated by the fact that undergraduate students struggle to understand statistics. Actually, that’s putting it mildly: a large fraction of undergraduates simply refuse to understand statistics; mention a requirement for statistical data analysis in your course and you’ll get eye-rolling, groans, or (if it’s…

Companies are overselling the accuracy of a new generation of prenatal tests and doing little to educate expecting parents or their doctors about the significant risk of false alarms.

Nate Silver Calls Competing Election Forecaster's Model 'Wrong'
This post has been updated. Election forecaster Nate Silver did something unusual on Wednesday: He openly criticized another election forecaster's modeling. The target of his critique was Princeton University's Sam Wang, whose 2014 forecasts have been published by The New Yorker. Silver took the unusual step, he wrote at FiveThirtyEight, because of the disparity between his model and Wang's. Silver's most recent forecast Tuesday gave the Republicans a 53 percent chance of taking over the Senate. Wang's Wednesday forecast shows Democrats with a 70 percent chance of keeping it.
