Wordsum Sample Test

Over at MR, Alex Tabarrok highlighted a chart made by Razib Khan about a Wordsum test (a test given in the GSS survey that correlates with IQ) and those who drink alcohol.  In the comments, Razib pointed us towards the GSS browser to test a commenter’s theory that drinking alcohol matters less among those that have completed college.

Attended college:

Didn’t attend college:

After looking at this post, one of my friends wanted to see an actual Wordsum test. Here is one illustrative example that I found in a paper:

From: Huang, Min-Hsiung, Hauser, Robert M. Trends in Black-White Test Score Differentials: II. The WORDSUM Vocabulary Test (1996) (page 30 of the pdf)

i am so confused
1-10 is the number right out of 10 on the test. The percent is the percent that meetpositive on the behaviour, e.g., ever drink alcoholic beverages.
It looks linear within the college set, but I'm not sure I see a pattern in the non-college set.

The bigger pattern seems to be an average of 60% vs 70%, the college-respondents drink less.
College is the top chart. The point is that alcohol consumption and a proxy for intelligence (or general knowledge) seem to have no relationship for those who attended college, but has a strong relationship for those who didn't. I don't think there is causation here, there is another (non-causal) correlation between certain religion sects and drinking and religion sects and IQ that comes to the forefront in the "didn't attend college" stats but doesn't show up for those who attended college.
oh ok, thanks. I was reading it backwards.
That makes the overall % teetotallers more interesting. So the college grads drink more often than non-college. Well well.
Something else has to be going on with the college-educated respondents who got 0, 1, or 2 right. How could you even get into college if you don't know -- eg, lift, broaden, concern, ...
i did the test for fun and i think i got 8/10, honestly i have no idea what cloistered and sedulous mean. on another note, does this data help prove that people who go to college are generally more intellectual and thus consume less alcohol and have a broader vocabulary or that college helps expand vocabulary and lower alcohol consumption?
also interesting - the people who said that they do drink alcohol seem to have an average of higher scores
