Correct Answer

✅ Option b — class frequency to the class length

All Options:

  • Aclass frequency to the total frequency
  • Bclass frequency to the class length
  • Cclass length to the class frequency
  • Dclass frequency to the cumulative frequency

Detailed Solution & Explanation

The frequency density of a class interval in a continuous frequency distribution is defined as the ratio of the frequency of that class to its class length (or class width):
Frequency Density=Class FrequencyClass Length\text{Frequency Density} = \frac{\text{Class Frequency}}{\text{Class Length}} Where:
- **Class Frequency** is the number of observations falling within the class interval.
- **Class Length** is the width of the class interval (Upper limit −\displaystyle - Lower limit).

Hence, **Option B** is the correct answer.
