electric

These data are based on an educational TV show for children called "The Electric Company". In each of four grades, the classes were 
randomized into treated (TV show) and control groups (no TV show). At the beginning and at the end of the school year, students in all the classes were given a reading test. The average test scores per class were recorded.
