What does a 73 IQ mean?

A score of 73 is 1.80 standard deviations below the average of 100. On most IQ tests one standard deviation, the typical distance from the average, is 15 points, so 73 is 27 points away.

73 sits near the bottom of the 70 to 79 band, 7 points below the next band up. About 6 in 100 people score from 70 to 79, the band that holds 73. A 73 on its own is not a diagnosis of anything. Intellectual disability needs limits in two areas at once. One is reasoning, shown by a score around 70 or as high as 75. The other is adaptive behavior: the conceptual, social and practical skills of daily life. Both must begin before age 22.

What percentile is an IQ of 73?

A score of 73 is at the 3.59th percentile. That percentile is the share of people who score lower than 73, not the share of questions right. Five points higher, 78 is at the 7.12th percentile.

How rare is an IQ of 73?

About 1 in 28 people score 73 or lower. In a town of 100,000 people, about 3,600 would score 73 or lower.

For every 100 people who score exactly 100, about 20 score exactly 73. These figures for 73 come from the normal curve that IQ scales are built on, and the IQ calculator works out any other score.

What would 73 be on other tests?

Not every test would print 73 for this position. Older Stanford-Binet forms and many school tests use a standard deviation of 16; there, the same position as 73 is about 71. On a scale with a standard deviation of 24, used by the Cattell test, it is about 57. 73, 71 and 57 all mean the same percentile.

Is 73 a good IQ score?

The scale does not grade the person behind a 73; it places one result among other people’s results. As a position, 73 is far below the average of 100. What a 73 is useful for depends on the purpose, and a single online result is too rough for decisions about school, work or support. A 73 describes some kinds of reasoning on one test, on one day, and leaves out a great deal that matters, such as effort, knowledge and character.

What should you do with a 73 result?

First, look at where the 73 came from. An online 73 is a rough estimate, and any single score moves between sittings. If you need an assessment for school, work or support after a 73, a psychologist can give a full test and look at everyday skills too. The IQ scale guide explains scores like 73 with care.

What does an online result of 73 mean?

An online result of 73 is an estimate. When our test shows 73, the estimated range next to it usually reaches below 70, the lowest score our test reports, so it is shown as “up to 87” or close to that. That range for 73 is provisional: it comes from our scoring model and a simulation, not yet from real test takers. Our methodology shows how the range is made.

An unsupervised online 73 may also run a little high: a large review found a gap of about 3 IQ points. Taking the same kind of test again usually raises a score like 73 a little, mostly on the first retakes. Our guide are IQ tests accurate covers this in depth.
