How do you determine percentile of crash test dummy?

To determine the percentile of a crash test dummy, you first need to establish a reference population, typically based on anthropometric data that represents the target demographic (e.g., adult males, females, or children). The dimensions and mass of the crash test dummy are then compared to this population data to see where it falls on the percentile scale. For example, if a dummy's height is at the 75th percentile, it means it is taller than 75% of the reference population. This information helps ensure that vehicle safety features accommodate a range of body sizes.
