Answer

To solve the question, "The number of times a particular observation occurs in the given data is called its ___," we need to identify the correct term that describes this concept in data handling.

### Step-by-Step Solution:

1. **Understanding the Concept**:
- In statistics, when we analyze data, we often need to know how many times a specific value or observation appears in a dataset. This count is crucial for understanding the distribution of the data.

2. **Identifying the Term**:
- The term that describes the count of occurrences of a particular observation in a dataset is known as "frequency."

3. **Example for Clarity**:
- Let's consider a simple dataset: 10, 20, 5, 20, 3, 10, 20, 5.
- In this dataset, we can count how many times each number appears:
- The number 10 appears 2 times.
- The number 20 appears 3 times.
- The number 5 appears 2 times.
- The number 3 appears 1 time.

4. **Conclusion**:
- From the example, we can see that the frequency of the number 20 is 3 because it occurs three times in the dataset.
- Therefore, the answer to the question is "frequency."

### Final Answer:
The number of times a particular observation occurs in the given data is called its **frequency**.
