The value is defined by your test results. The tests generate scores that are roughly normally distributed up to about an IQ of 130 (two standard deviations), but then have many more people at high IQs than a bell curve would predict.
Most IQ tests can't even measure above 155 or so, anyway, and they obviously can't measure below 0. So it's a little silly to talk about them being normally distributed.
