Answer

To solve the question, we need to identify the term that describes the most frequently occurring number in a set of values.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Mean**: This is the average of a set of numbers, calculated by adding all the numbers together and dividing by the count of numbers.
- **Median**: This is the middle value in a set of numbers when they are arranged in ascending or descending order.
- **Mode**: This is the number that appears most frequently in a data set.
- **Range**: This is the difference between the highest and lowest values in a data set.

2. **Identifying the Correct Term**:
- The question specifically asks for the term that refers to the most frequently occurring number.
- By definition, the mode is the value that appears most often in a data set.

3. **Conclusion**:
- Since the mode is defined as the most frequently occurring number, we can conclude that the correct answer is **option (iii) mode**.

### Final Answer:
The most frequently occurring number in a set of values is called **mode** (option iii).
