Axes for Frequency Curve
A Frequency Curve is obtained by plotting which values on the X-axis and Y-axis?
- X-axis: Class limits; Y-axis: Tally marks
- X-axis: Class marks; Y-axis: Frequency — Correct Answer
- X-axis: Frequency; Y-axis: Class marks
- X-axis: Class intervals; Y-axis: Range
Explanation:
Correct Answer Explanation
To obtain the frequency curve, we plot Class Marks on the X-axis and Frequency on the Y-axis.
Key Points:
- A Frequency Curve is the graphic representation of a frequency distribution.
- Class marks (mid-points) are used on the X-axis, not class limits.
- For example: Class 40–50 → Class Mark 45 is plotted on X-axis with frequency 21 on Y-axis.
- A smoother curve can be obtained with unequal class intervals that better represent the concentration of data.
