Where 102 sits on the IQ scale
A score of 102 is 2 points above the mean. Dividing by the standard deviation gives (102 − 100) ÷ 15 = 0.13. The normal cumulative distribution converts that standardized position into percentile 55.3.
This lies in the upper half of the central 85–115 interval. It is above the scale mean, but the total alone does not identify a particular strength in memory, numbers or spatial reasoning.
How common is a score of 102?
Approximately 44.7% of this model lies at or above 102—about 1 in 2. This is a cumulative share, not the chance of scoring exactly 102. A continuous model does not assign a positive probability to one exact value.
Compared with IQ 100, the reference percentile is 5.3 percentage points higher. Equal IQ-point gaps do not create equal percentile gaps: the middle of the bell curve contains more area than its ends.

How this relates to starp
starp's current scoring map does not produce exactly 102. Its neighboring results are 100 for 22 correct answers and 104 for 23 correct answers out of 30. This guide explains the conventional scale value 102; it does not invent an intermediate starp result.

Questions about IQ 102
Is 102 a good IQ score?
102 is above the reference mean of 100. It is a higher score on that scale, but a number alone cannot establish a specific skill profile or predict success.
What percentile is an IQ of 102?
On a normal scale with mean 100 and standard deviation 15, 102 corresponds to approximately percentile 55.3. Around 44.7% of that model lies at or above it. Use an assessment's own norms for an actual reported rank.
Does an IQ of 102 mean 102% correct?
No. IQ is a scaled score. Percentage correct depends on the questions and scoring rules; percentile describes a relative position. These three quantities are not interchangeable.
