Detailed Solution & Explanation
Measures of dispersion describe the spread of the data, which include the Range, Quartile Deviation, Mean Deviation, and Standard Deviation. The concurrent deviation method is a method used to study correlation (the relationship between two variables) rather than the dispersion of a single variable.
Hence, **Option D** is the correct answer.

Do not just memorize formulas; ICAI loves asking about the mathematical properties (e.g., 'sum of deviations from the AM is always zero'). You can usually eliminate 2 options just by knowing the properties.
