A Head Start Reevaluation: Positive Effects Are Not Yet Demonstrable
Bentler, Peter M.; Woodward, J. Arthur – Evaluation Quarterly, 1978
The Head Start data analyzed by Magidson (1977) were reanalyzed using Joreskog's (1976) LISREL computer program methodology. The hypothesis that the Head Start program produced zero effects on the cognitive abilities of its participants was evaluated by several Chi Square tests. In all cases, the null hypothesis could not be rejected. (Author/CTM)
