Who on here has had one of them IQ tests? How conclusive or inconclusive for that matter were the results? What do you all think about it? Shot from whichever angle you wish. I'll be back.
Many years ago....can't even remember the score, to be honest. Either 149 or 159. I don't remember and it has not really mattered to me. Interesting, though....would I have achieved more (by social standards) had I given more notice to my score?
I was wondering what parameters it measures and by what means precisely; also if any statistical data is used to support it; what are the variables, etc...
The IQ test itself is generally used for statistical data. It is a measurement of standard deviations on a Gaussian Bell Curve. The modern version uses a median or center value of 100 with a standard deviation of 15. So then a score 85-115 would represent the area of the bell curve that most people fit into. Among the most common criticisms of the test are that the methodology is outdated, and that test bias exists.
In response to: 119-162 is a very wide margin it would be interesting to do a study on cases like that and see what might have caused the difference.
I would assume that these were tests taken online, and it must be noted that IQ tests in any medium come in various forms. Some use a single type of item, others use several different subsets. This might explain the wide margin.
It should also be be noted that many critics, including an inventor of intelligence tests in the early 20th century, Alfred Binet, insist that human intelligence cannot be measured as a fixed entity or as a linear surface can be measured.
"Standard deviation" is just a statistical term that represents a measure of variability.
The three types of averages are mean, medium, and mode.
When we say average we usually think of the arithmatic mean (which is also a statistical mean), or the sum of all values in the range, divided by the number of values in the range.
The medium would be the middle number in the range.
The mode would be the number that appears most frequently. (a range can have more than one mode)
The range would be the largest value of the set minus the smallest value of the set.
So I guess that the shortest answer to your question would be "yes"
