1 out of 2.  The mean is 100.  The other statistic is the
standard deviation, and it's 15.  The index "IQ" was invented
and scaled to meet exactly those two criteria.  Whether this
index is correlated with any real phenomenon is, of course,
another matter.

For those of you unfamiliar with statistics, mean=100 and sd=15
imply that approximately 95% of the population is expected to score
between 70 and 130.  A sobering thought.
