Detailed Solution & Explanation
A variable is said to be continuous if it can assume any real value within a specified range, including fractional and decimal values. Income fits this definition because it is measured in monetary units (e.g., rupees and paise, dollars and cents) and can take any value along a continuous scale (for instance, a salary can be ).
When we group households or individuals by their income levels into class intervals (such as , , etc.), we are dealing with a continuous frequency distribution.
- A **discrete variable** can only assume specific isolated, integer values (e.g., number of children in a family).
- An **attribute** is a qualitative characteristic that cannot be measured numerically (e.g., gender, nationality).
Therefore, the distribution of income is a frequency distribution of a continuous variable (Option A).
Hence, **Option A** is the correct answer.
