Correct Answer Explanation
A Frequency Array is the classification of data for a discrete variable.
Key Points:
- Since a discrete variable takes only certain values (integers), frequencies correspond to each integral value.
- Example: Size of Household (1, 2, 3, 4, 5, 6, 7, 8) with corresponding frequencies.
- There are no class intervals in a frequency array — each value stands alone.
- A Frequency Distribution (with class intervals) is used for continuous variables.
