q3 i? The person-oriented method predicted number of days absent significantly better than the categorical method; no significant differences emerged among methods for days tardy. → Dowdy 2007

Dowdy, E., & Kamphaus, R. W. (2007). A Comparison of Classification Methods for Use in Predicting School-Based Outcomes. The California School Psychologist, 12, 121-132. https://eric.ed.gov/?id=EJ896649 doi:10.1007/bf03340936

q3 · i? · associational · r2

Regression comparison for attendance outcomes in the 558-child sample. Predicted days absent correlated .246 (cluster) versus .174 (categorical); R squared values were .030-.060 for absence and .006-.017 for tardiness. The article reports "No significant differences were noted between the three possible methods of predicting the number of days a student was tardy."

"the person-oriented method predicted the number of days absent significantly better than the categorical method. However, no other significant differences were noted for days absent."
