Is the average test score for Class A higher than the average test score for Class B? Statement 1: The median test score for Class A is 85, and the median test score for Class B is 80. Statement 2: All students in Class A scored between 70 and 95, and all students in Class B scored between 60 and 90.
✓ Correct Answer: Option D
Statement 1 (medians) doesn't guarantee the average. Statement 2 (ranges) doesn't tell us about the distribution within the range. Even together, knowing the median and range for each class does not provide enough information to definitively compare their averages, as skewness could vary.
