Answer 1

Proper IQ tests, such as the Welscher Adult Intelligence Scale, measure performance of numerous tasks across several congnitive categories.

Each test category, such as verbal comprehension, perceptual reasoning, working memory, etc. consists of several individual tests which are scored as a percentile against a vast population of people already tested. Categorical scores are combined through a rubric to produce a score which represents an overall percetile.

The score itself is not a percentile.
