What’s your sign? The University of Chicago’s General Social Survey (GSS) is the nation’s most important social science sample survey. For reasons known only to social scientists, the GSS regularly asks a random sample of people their astrological sign.

Here are the counts of responses from a recent GSS:

Sign: Aries Taurus Gemini Cancer Leo Virgo Count: 321 360 367 374 383 402 Sign: Libra Scorpio Sagittarius Capricorn Aquarius Pisces Count: 392 329 331 354 376 355 If births are spread uniformly across the year, we expect all 12 signs to be equally likely. Do these data provide convincing evidence that all 12 signs are not equally likely? If you find a significant result, perform a follow-up analysis.
