Question

Quizplus · Accepted Answer

The Bayley Scales of Infant and Toddler Development use norms based on a large sample of children to determine what is average. A child's scores are considered average when they are similar to the scores of the middle 50% of children in the same age group, meaning when the infant passes the test at the age at which 50% of other infants pass the test.
