Percentile
Reasoning Test With Percentile: Why Comparison Changes the Result
A reasoning test with percentile is more satisfying than a plain score because it answers the comparison question: how did I do compared with others?
Raw score is only the start
Two users can have the same correct count but different response times and different category patterns. Percentile helps summarize the overall session.
Comparison needs a benchmark
The comparison pool should represent realistic performance, not perfect users and not all-zero users. As real user data grows, the benchmark becomes more useful.
Why wording matters
Reports should clearly say whether the user ranked higher than a percentage of users or is in the top percentage. Those are different statements.
Quick answers
What does 75th percentile mean?
It means the result ranked higher than about 75% of compared sessions.
Is top 25% the same as 75th percentile?
Yes, roughly. Higher percentile means smaller top-percent group.
