How do you convert Raven score to IQ?
Find the score that corresponds to the relative frequency of the z-score. For a normal distribution, the relative frequency 0.2486 corresponds to a value of 111. Therefore, a Raven Score of 26 would convert to an IQ of 111.
What is raw score in IQ test?
For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation 15. This results in approximately two-thirds of the population scoring between IQ 85 and IQ 115 and about 2.5 percent each above 130 and below 70. Scores from intelligence tests are estimates of intelligence.
Is the Raven IQ test timed?
Abstract. The Raven Advanced Progressive Matrices Test (APM) is a well-known measure of higher order general mental ability. The time to administer the test, 40 to 60 minutes, is sometimes regarded as a drawback. This 20-minute timed version proves to be an adequate predictor of the untimed APM score.

How is the Raven SPM different from other IQ tests?
Unlike other IQ tests that provide a wide range of intelligence scores from their subtests, Raven’s SPM produces a single raw score from the 60 items (i.e. questions/problems) presented in the test. The test’s 60 items are broken into 5 sets of 12 and do not include a time limit.
