Detailed Solution & Explanation
The measures of central tendency are averages that indicate the center of a probability distribution (these include the Mean, Median, and Mode). On the other hand, the Quartile Deviation is a measure of dispersion, which describes the spread or variability of the data rather than its central location.
Hence, **Option C** 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.
