Aug 1, 2023 · The percentile of a score is the percentage of people who score equal to or below the score. For example, an IQ score of 70 is in the 2nd percentile (for SD = 15), which means that only 2% of people score 70 or lower. IQ 125 is at the 95th percentile - 95% of people have an IQ equal to or less than 125. This means 5% of the population score higher. In general, you'll need to know two quantiles of a normal distribution in order to determine $\mu$ and $\sigma.$. Here is an example based roughly on the part of the Empirical Rule that says about 68% of the probability under a normal curve lies between $\mu \pm \sigma.$ Thus quantiles .16 and .84 of $\mathsf{Norm}(\mu=100,\sigma=15)$ …It's helpful to sort them in ascending order. Of these 13 data values, 4 are less than or equal to the data value 153.
