A school psychologist decided to separate some classes by gender to see if learning improved. She looked at studded scores on the final exam and obtained the following information: Students in boy-girl classrooms obtained an average of 71.4 on their final exams with a standard deviation on 10.8 whereas students on single-gendered classrooms obtained an average of 75.9 on their final exams with a standard deviation of 8.2. What else does the psychologist need to know or think about when interpreting this information?
