Take this test and post your percentile scores. Percentile tells how many people scored lower than you. So if you get a 99%, that means only 1% scored higher than you.

Mine was 93%.

I've seen better... I'm not telling what I got...

54%.....Gogeta, looks like I'm lucky I'm not dead!

Each of us has different abilities. The test only tests visual IQ. I might have scored better than you, but my performance is terrible when it comes to verbal things like words, anagrams, names of cities etc.

79%.

Because of the way the results are compiled, the earlier you take the test, the higher your potential score will be; this makes comparison of each other scores meaningless.

Not really. Suppose you would have scored x% a month ago. If you take the test now, your score will be less only if people who have taken the test in the last month score greater than x% on an average. If they score less than x% average, then your score will be higher.

So, assuming that many people have taken the test until now, if you score >50% your score would have been lower a month ago. If you score <50%, then it would have been higher a month ago. This is because The average score during the month should not deviate much from 50% (we assumed that many people have already taken the test).

That’s not how it works; at least, it’s not what I got from the text shown at the end of the tests. Let me give you an example:

There are 15 questions, so each question is worth about 7% (6.667%). So, the first person to take the test scores 6/15, or 40%, but they’re the first, so their score is given as 100%, because nobody scored higher than them – because we’re not shown how many people have taken the test, we have no way of knowing where you fit in the ranked list. So, the second person to take the test scores 9/15, or 60%, again, shows as 100%, because nobody has scored higher. Now, if a third person comes along and scores 7/15, or 46%, their score shows as 66%, because basically 1/3 (or 33%) of the people who’ve taken the test scored higher than they did, however, in comparison to the first person, who only scored 6/15 compared to the third person who scored 7/15, there’s a discrepancy -- 66% for the higher actual score, compared to 100% given for the lower score. As more people take the test it dilutes this somewhat, but doesn’t change the fact that the earlier you take the test, the higher your potential score.

The test doesn’t tell you how many questions you got right, only how many people scored lower than you, meaning you can ONLY compare the scores of people who took the test simultaneously, because the yardstick by which the percentage values are given is constantly changing.

You are only considering the case where the newcomer scores more than the previous test takers. if, suppose, the first one scores 6/15, the second scores 8/15, the third scores 9/15 and the fourth scores 8/15.

the second one gets 0%, while the fourth gets 25%, although their scores are same. you are only considering one case, not the other. their are chances for both.

if many people have taken the test, the effect will be diluted, as you said.

Rhort

Well, this is effectively my point; it doesn't matter which way around it happens, it's meaningless to compare these percentages.

ssj4Gogeta

suppose 10000 people have taken the test, then >100 people will make a difference of 1%, if all of them score ABOVE you, which is unlikely. it's likely that the average score kept near 50%. then there wont be much difference in the scoring. but of course, this is true only if many people have already taken the test.

This seems right as it looks the results were explained this way to provide a competitive hook to promote the site....hence the monthly turnover of results allows you to improve even tho' the disclaimer points out the results would be inaccurate 'cos you would then be learning.

It's marketing...just enough sense to hold your casual attention but not enough to stand up to scrutiny.

The only accurate comparasion (& the data he's after) would be against the results of everyone who ever took the test once with the results updated for everyone after each test. As you can take this test twice (after all he needs hits to fund his research) this database should have been rendered useless for that purpose except people who insist on ignoring the disclaimer are redirected by the 1st screen...

Since the %s so far seem to reflect straight scores out of 15 (don't they?) the 'comparasion' is designed to get those 2nd hits....marketing.

ssj4Gogeta

Well, first time I took this test in May and now I took it again (I answered 'no' when it asked whether I've taken the test before), and I marked exactly the same options as before. I scored 93% this time too!!!

This probably means that so many people have taken this test that the results are more or less accurate.

Titomike

or you scored 14/15 twice...isn't that far more likely than you were ranked exactly the same despite the intervening tests taken?....especially since you gave the same answers? Why are the results multiples of 6.67%?

Interestingly, since you were able to do that the data has to be corrupt....you can,t improve your 'I.Q.' by retaking the same test otherwise a dumbass like me would just spend a couple of days answering randomly & recording my answers & results til I cracked it and was 100% smart.

ssj4Gogeta

i might have not scored 14/15. what makes you think so?

Titomike

'Cos that's the score that particular multiple of 6.67% represents.

Go in again, change one of your answers...if, according to my theory you choose an answer you had right (1in 14 chance...good enough) your result will be 87%

ssj4Gogeta

my little bro got 28. its not a multiple of 100/15, even after rounding he should have got 27.

Titomike

Yeah....your right neither is 79 should be 80.....guess that's why I got 54

However the bit about repeating the test is correct, isn't it?

Rhort

The "6.67%" represents the score for each correct answer (15 questions, 6.667% each), not the total percentage given at the end of the test; that's why it doesn't appear to add up. The percentage value given at the end of the test is representative of how many people scored lower that you, not how many answers you got correct.

ssj4Gogeta

yes, if it represented the actual percentage of correct answers, then we wouldn't have this discussion would we?
