In 1999, schools in Massachusetts were given improvement goals. For each school, the Department of Education tabulated the difference in the average score achieved by students on standardized educational tests in 1999 and 2000. It was quickly noted that most of the worst- performing schools had met their goals, which the Department of Education took as confirmation of the soundness of their policies. However, it was also noted that many of the supposedly best schools in the state had failed to meet their goals. What is the statistical term that explains this situation?
