Score Context
This guide is part of the Rice Purity Hub IQ knowledge cluster. It explains the topic in plain language, uses standard psychometric terms, and links back to the free IQ test so readers can compare ideas with a private browser-scored estimate.
Limits And Clinical Use
IQ scores use a normal distribution with a mean of 100 and a standard deviation of 15. Percentiles describe how a score compares with a norm group, not a person's worth, creativity, kindness, or future.
How This Connects To The IQ Test
Online tests can be useful for self-reflection, but they are not clinical assessments. A licensed psychologist must administer instruments such as the WAIS, Stanford-Binet, or WISC when results affect diagnosis, placement, or accommodations.
