Ratio developmental quotients (DQs) from Bayley Scales administered after age 30 months were compared to Stanford-Binet IQs secured later. Means from two testings of 42 mentally retarded children were almost identical. The DQs and IQs correlated .81, p less than .001. These findings justify the use of Bayley ratio quotients to determine intellectual level of children who are too old for the Bayley norms but too retarded to earn a basal level on the Stanford-Binet.
将30个月龄后进行的贝利婴幼儿发展量表得出的发展商数（DQ）与之后测得的斯坦福-比奈智力量表智商进行比较。对42名智力发育迟缓儿童的两次测试结果均值几乎相同。发展商数与智商的相关性为0.81，p值小于0.001。这些发现证明，对于那些年龄超出贝利量表常模范围但智力过于迟缓以至于无法在斯坦福-比奈智力量表上获得基础分数的儿童，可以使用贝利比率商数来确定其智力水平。
