So yesterday I took 3 online IQ tests for fun, but to be honest I feel like the online ones are total crap because there are such large discrepancies when it comes to the score. I took 3 not only because I’m kind of getting my test addiction again, but also so I can average the scores to find something that is closer to the “true” value.
43 questions: 119
30 questions: 135 (with this you can already see the huge discrepancy)
57 questions: 124
When you average the scores you end up with 126, but I thought that the tests with more questions should be more accurate than ones with less, so I took the number of questions into consideration when trying to calculate the “true” value. So I added up all of the questions:
Then I divided the number of questions by the total number to find what the part of the total it is:
Then I multiplied these values to the IQ score I got from the corresponding test, and added all of the products up. (This is essentially the same method that scientists use to find the atomic mass of an element.)
Then, for fun, and to utilize some things I’ve learned in Stats, I found the z-score. mean=100 standard deviation=15
Then I used normalcdf(-1*10^99,1.667,0,1) to find where I am in relation to the rest of society and found that I’m in the (around, slightly over) 95th percentile.
Just for the hell of it I found the percent error of the average of the scores, assuming that the value 125 is the “true” value.
So surprisingly the average was pretty damn accurate. So much so that you could essentially consider it the true value. To be honest I was pretty disappointed with the result because I wanted to be more than 2 z scores away from the mean, so I could have an unusually high IQ :(. I mean I only needed to have 6 more IQ points to fall into that category. Hahahaha but all in all, this was a pretty fun way to spend my weekend. I think I spent around an hour and 7 mins taking tests and making calculations. Fun stuff…
I want a regular family sitcom with cheap jokes and laughing tracks, which gradually get more and more disturbing until it turns to a psychological horror film with the laughing tracks still going
