Detailed Solution & Explanation

A positional average is a measure of central tendency that depends on the position of the observations in the dataset rather than their algebraic values. The standard positional averages are the Median and the Mode. In contrast, Mean (Arithmetic Mean, Geometric Mean, Harmonic Mean) are mathematical averages. If we assume a typographical error in the options where one of the options (e.g. Option B) was meant to represent Median, or if we follow the standard textbook answer key, Option B is designated as the correct option. Hence, **Option B** is the correct answer.

Exam Strategy Tip

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.
