Correct Answer Explanation
For "less than" ogive, cumulative frequencies are plotted against the respective upper limits of the class intervals.
Key Points:
- For "more than" ogive, cumulative frequencies are plotted against lower class limits.
- Cumulative frequencies are plotted along Y-axis and class limits along X-axis.
- "Less than" ogive starts from the lowest upper limit and moves upward.
- This plotting method is essential for finding the median graphically.
Why Other Options Are Wrong
- A. Lower class limits: These are used for "more than" ogive.
- C. Mid-points: Mid-points are used in frequency polygon, not ogive.
- D. Class frequencies: Frequencies go on Y-axis, not X-axis.
