The data do not provide a universal answer

Unfortunately, there's no one-size-fits-all answer.Data can be grouped and divided in any number of ways,and overall numbers may sometimes give a more accurate picture than data divided into misleading or arbitrary categories.All we can do is carefully study the actual situations the statistics describe and consider whether lurking variables may be present.Otherwise, we leave ourselves vulnerable to those who would use data to manipulate others and promote their own agendas.
