Last Year, the Average Math SAT Score for Students at One

question 118

Essay

Last year, the average math SAT score for students at one school was 475. The headmaster introduced new
teaching methods hoping to improve scores. This year, the mean math SAT score for a sample of students was
481. Is there statistically significant evidence that the new teaching method is effective? If the teaching method
had no effect, there would be roughly a 3 in 10 chance of seeing such an increase. Does the result have
statistical significance? Why or why not? Does the result have practical significance?
