Describe the importance of percentile ranks and how they are used in explaining differences in development
What will be an ideal response
Percentile ranks allow comparisons of growth between children and comparison of
children to themselves to chart their growth. Percentiles can be used to alert parents
and professionals if a child is not growing as he or she should. They can be used to
explain differences in development among children, for example, a child who is at
the 90th percentile in height and weight is developing normally, as is the child who is
at the 40th percentile in both height and weight.
