Select an answer

A Frequency Curve is obtained by plotting which values on the X-axis and Y-axis?

  1. X-axis: Class limits; Y-axis: Tally marks
  2. X-axis: Class marks; Y-axis: Frequency — Correct Answer
  3. X-axis: Frequency; Y-axis: Class marks
  4. 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.
