- 主题:智商的标准差是15吗
智商的标准差是15吗？智商以100为平均值，15为标准差？也就是1sigma=15,如果两个人的智商差2个sigma,30,就会交流困难，即使智商低的那一方智商高于平均值100.

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.
