Correct Answer Explanation
Each class in a frequency distribution table is bounded by Class Limits — the two ends of a class.
Key Definitions:
- Lower Class Limit: The lowest value of a class (e.g., for class 60–70, lower limit = 60).
- Upper Class Limit: The highest value of a class (e.g., for class 60–70, upper limit = 70).
- Class Interval / Class Width: Difference between upper and lower class limit (70 − 60 = 10).
- Class Mark / Mid-Point: (Upper Class Limit + Lower Class Limit) / 2 = (60+70)/2 = 65.
