Re: Visual IQ 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.
