Changing Information

A research assistant is responsible for recruiting families with children ages 12 to 24 months old for a study of language and learning. She is having trouble finding families who are interested in participating. However, she finds a family who are willing to participate with 27 month-old twins. So that she can include the twins in the study, she records their age as 24 months instead of their real age. The twins are enrolled in the study and the Principal Investigator publishes information on the normal development of 24 month olds based on the data collected from these older children. This information is used to affect recommendations for parents on how to stimulate their child's learning and language development.
