How much math does a pediatrician need?

Yes. For instance, the doctor would need to measure medications compared to the size ands age of children. He/she would need to measure their growth, among other things. The doctor would need to be able to read and fully understand professional journals, where developments in pediatric medicine are constantly being reviewed. Journal studies very often involve sophisticated research models where an understanding of statistics is critical. The doctor must know how to decide if a given protocol or medication is worth using in the way described in the study.
