Average is not enough. If you have 10 people who have an IQ of 80 and one with an IQ of 300, that'd also average to 100. What matters here is the (roughly) gaussian distribution, too.
- dragontamer 9y agoThe IQ Test assumes a Gaussian distribution by definition. One-standard deviation above and below is defined as 85 to 115. Two standard deviations (which includes 95% of the population) is between 70 and 130. ---------- Your proposition that someone has an IQ Score of 13+ Sigma above the average only demonstrates your lack of understanding of the IQ test. There's literally no one that's that high. The IQ Test I think only measures like +/- 4 sigma or so... 40 to 160.
- Kenji 9y agoIt was an example with simple numbers. My goodness, I forgot how pedantic people are here. If someone does not understand that average is not median, then I'm not going to talk about standard deviation...
- dragontamer 9y agoThen just say what you're trying to say. And this time, don't use subjects like "IQ Score" unless you actually know what the hell it means. IQ Score means something particular. An IQ Score of 100 is literally average (Mean, Median, AND Mode), because the IQ Test assumes a Gaussian distribution. 115 is +1 Sigma, and 130 is +2 Sigma. ----------- If you're trying to make a statement on intelligence that doesn't have to do with the Gaussian Distribution, then maybe you should stop using "IQ" as your metric. Are you trying to say that you think that general intelligence is bimodal or otherwise a non-normal distribution?
- Kenji 9y agoAt this point, you are literally trolling me.
- paulpauper 9y agoTechnically, tests can be devised to extrapolate IQs to the 200+ range . One such test is reading age and talking age. If someone attains a cognitive milestone at such an early age that is only achievable by one in a billion people, the person has a 1/billion rarity IQ or IQ of 200 (assuming a SD of 15).
- vacri 9y agoThat's not 'technically' at all. It's an approximation. The actual IQ test is multivariate and takes several hours to administer, and needs to be given by a trained professional. Hitting a single milestone super-early just means that you've hit a milestone super-early, not that your general intelligence is super-high.
- watwut 9y agoEarly reading is result of good memory at early age. That is about it. In general, the speed of brain development and how intelligent you will be in the end are not closely related.
