About IQ test

The Raven's Progressive Matrices test is a non-verbal test of abstract thinking that measures fluid intelligence (Gf) - the ability to reason and solve problems. It is a culture fair multiple choice IQ test that provides insight into the ability to observe, solve problems, and learn. The test measures only a subset of intellectual abilities, and valid conclusions cannot be drawn about the overall intelligence of the person. The test consists of 54 questions that gradually become more complex. Respondents choose geometric shapes to properly complete larger images. The result of the test is determined by the number of correct answers and the age of the respondent. However, the final score is not linearly related to the number of correct answers. The evaluation of the test is based on a study of a large sample of anonymous results of users of the app in different age categories and is continuously refined. The advantage of the test is its non-verbal nature, which avoids cultural and linguistic discrepancies. However, the disadvantage of the test is that repeating it may improve the result. The results are distributed on the so-called Gaussian curve into several percentile intervals on an overall scale from 0 to 160 intelligence quotient points, with the majority of the population corresponding to IQ values between 90 and 110.
