A(z) Child Growth Percentile kiszámítása
Mi az a Child Growth Percentile?
Growth percentiles compare a child's height and weight to a reference population of the same age and sex. A child at the 50th percentile is exactly average; 10th percentile is shorter/lighter than 90% of peers; 90th percentile is taller/heavier than 90% of peers.
