View Complete Answer & Explanation
Question (English)
The frequency curve is obtained by drawing a:
- Straight line through all frequency points
- Smooth freehand curve passing through frequency polygon points as closely as possible ✓ Correct
- Series of bars touching each other
- Step function graph
Explanation:
Correct Answer Explanation
The frequency curve is obtained by drawing a smooth freehand curve passing through the points of the frequency polygon as closely as possible.
Key Points:
- It may not necessarily pass through all the points of the frequency polygon.
- It provides a smoother representation of the frequency distribution.
- It helps in understanding the overall shape and pattern of the distribution.
- The curve passes through the polygon points as closely as possible.
Why Other Options Are Wrong
- A. Straight line: A frequency curve is smooth, not a straight line.
- C. Bars touching each other: This describes a histogram.
- D. Step function: Frequency curves are smooth, not stepped.
