Appendix Data Set Howell and Huessy (1985) reported on a study of 386 children who had, and had not, exhibited symptoms of attention deficit disorder (ADD)—previously known as hyperkinesis or minimal brain dysfunction—duringchildhood. In 1965 teachers of all second-grade school children in a number of schools in northwestern Vermont were asked to complete a questionnaire for each of their students dealing with behaviors commonly associated with ADD.

Questionnaires on these same children were again completed when the children were in the fourth and fifth grades and, for purposes of this data set only, those three scores were averaged to produce a score labeled ADDSC. The higher the score, the more ADD-like behaviors the child exhibited. At the end of ninth grade and again at the end of twelfth grade, information on the performances of these children was obtained from school records. These data offer the opportunity to examine questions about whether later behavior can be predicted from earlier behavior and to examine academically related variables and their interrelationships. A description of each variable follows. • ADDSCAverage of three ADD-like behavior scores

• • GENDER1 = male; 2 = female
• • REPEAT1 = repeated at least one grade; 0 = did not repeat
• • IQIQ obtained from a group-administered IQ test
• • ENGLLevel of English in 9th grade: 1 = college prep; 2 = general; 3 = remedial
• • ENGGGrade in English in 9th grade: 4 = A, etc.
• • GPAGrade point average in 9th grade
• • SOCPROBSocial problems in 9th grad: 1 = yes; 0 – no
• • DROPOUT1 = dropped out before completing high school; 0 = did not drop out
