Detailed Solution & Explanation
In statistical analysis and data organization:
1. **Frequency**: The frequency of a class interval (or value) is defined as the number of times a particular observation or data item occurs within that specific class interval during the period of observation.
2. **Mean**: The arithmetic mean is the average of a set of numerical values, calculated by dividing the sum of the values by their count:
3. **Cumulative Frequency**: This is the running total of the frequencies of all classes up to a certain point (e.g., the sum of the frequency of that class and all previous class frequencies in a 'less-than' type distribution).
Since the question asks for the number of times a particular item occurs within a class interval, it refers directly to the definition of 'Frequency', which is Option B.
Hence, **Option B** is the correct answer.
