Statistical stupidity from NPR

I am no longer surprised when NPR commits a statistical howler.

Today, they aired a touching story about a black hockey player and the racism that he endured. So far, so good.

But then, they go on to say this:

Despite stars like P.K. Subban and Evander Kane, hockey remains a stubbornly white sport. Only about five percent of NHL players are black 28 years after James.

Uh, exactly why is this a problem?

1. Backs are about 12.6 percent of the US population.

2, Blacks are about 2.9 percent of the Canadian population.

3. These days, the NHL gets about 50 percent (just over) of its players from Canada, and just under 25 percent from the United States.

So making the assumption that one would expect zero black players from other than the US or Canada (think of the hockey powers of this world), IF the representation were exactly proportional, we’d expect:

(.5)(2.9) + (.25)(12.6) = 4.6 percent, which is about what they have.

So why is 5 percent a problem? My guess: they assume that blacks are grossly over represented in football and basketball, they should be in hockey as well? If so, why?

Of course, this isn’t as bad as some idiot academic administrator with a Ph. D. insisting that everyone needs to be above the department average, but …well…let’s just say that I am cranky and that NPR comes across as smug.

  1. Has NPR upset with the disproportionate number of black basketball players? Or the lack of Asian basketball players? Gotta love National Prejudice Radio.
