【 在 snowfields 的大作中提到: 】
: The standard deviation for most IQ tests is set at 15 points. This means that about 68% of the population falls within one standard deviation of the mean – that’s between 85 and 115 IQ points. If you venture two standard deviations out (between 70 and 130), you’re looking at about 95% of the population.
: But wait, there’s more! Some IQ tests use different standard deviations. For example, the GT Score to IQ Conversion can be a bit tricky because it uses a different scale. It’s like trying to convert Fahrenheit to Celsius – doable, but you need to know the formula.
