Understanding IQ Scores: What Does a 27/30 on the Official Mensa Workout Suggest?

The Official Mensa Workout is a non-official test designed to give an indication of one's potential to qualify for Mensa. One common question among individuals who take this test is: what IQ range does a score of 27 out of 30 suggest?

What is the Official Mensa Workout?

The Official Mensa Workout is a series of challenging puzzles and tests created by Mensa, a global organization for high IQ individuals. It is not a formal IQ test but rather a preliminary tool to gauge one's cognitive abilities. Those interested in joining Mensa must typically achieve a score in the top 2% on a recognized IQ test, which usually corresponds to an IQ of around 130 or higher.

Interpreting a 27/30 Score

Scoring 27 out of 30 on the Official Mensa Workout suggests a high level of cognitive ability. However, translating this score directly into an IQ range is complex and requires some statistical background.

Estimating IQ from the Mensa Workout Score

Assuming the test is normally distributed, with a ceiling score of 145 (SD 15) and a lower boundary of 55 (SD 15), we can use the standardization formula:

Percent correct 27/30 90% Mean of the percentage score in a normal sample 100/2 50% (arithmetic mean) Standard deviation (SD) of the score in percentage 6 (since 100/6 16.666) z score (standard score) (27 - 50) / 16.666 -2.4

The z score indicates how many standard deviations an element is from the mean. Here, the z score of -2.4 suggests a score that is 2.4 standard deviations below the mean.

Converting Z Score to IQ

Taking the z score of -2.4, we can convert it to an IQ score:

IQ 55 (2.4 * 15) 55 36 91 (lower boundary) IQ 145 (2.4 * 15) 145 36 181 (upper boundary)

Thus, a score of 27 out of 30 on the Official Mensa Workout suggests an IQ range of approximately 91-181. However, this is an estimate, and individual IQ can vary based on various factors such as test environment, test anxiety, and cognitive abilities.

Conclusion

To get a more accurate IQ measurement, it is recommended to take a standardized IQ test administered by a qualified professional. This will provide a more reliable and comprehensive assessment of one's cognitive abilities.

Individuals who achieve scores in the top 2% on recognized IQ tests may qualify for Mensa. The Official Mensa Workout is a good indicator of one's potential but should not be relied upon as the sole metric for Mensa qualification.
