Correct Answer Explanation
Frequency expressed as a proportion or percentage of total frequency is known as Relative Frequency.
Key Points:
- Relative Frequency = (Class Frequency / Total Frequency) × 100%
- Example: Class 50–60 has frequency 23 out of 100 → Relative Frequency = 23%
- Class 0–10 has frequency 1 out of 100 → Relative Frequency = 1%
- Sum of all relative frequencies = 100% (or 1 if expressed as proportion).
- Relative frequency helps compare classes regardless of the total sample size.
