Comparing the proportions of the data values that are below a given number can help us evaluate differences between individuals in separate populations. These proportions are called percentiles. If p% p % of the values in a dataset are less than a number n n, then we say that n n is at the p p th percentile.For example, the definition of “high-potential” individuals with IQ scores between 120 and 129 could be used (Sartori 2019; Zanetti 2017) precisely because during the assessment they showed the potential to excel while obtaining an IQ score below 130 on standardized tests.Percentiles A percentile shows the relative position of the child's BMI, Weight or Height among children of the same sex and age.
