Question

The value of coefficient of skewness is:

• A. Negative
• B. Zero
• C. Positive
• D. Between 0 to 1

Hint:

Skewness:
- Positive: Mean > Median > Mode
- Negative: Mean < Median < Mode
- Zero: Mean = Median = Mode
In hydrology, data is often positively skewed.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Skewness measures the asymmetry of a frequency distribution.

Step 2: Detailed Explanation:
Coefficient of skewness can take different values:
- Negative: Left-skewed distribution (tail on the left).
- Zero: Symmetrical distribution.
- Positive: Right-skewed distribution (tail on the right).
Since the question asks for "the value of coefficient of skewness is", without specifying the distribution,
the general answer is that it can be positive, negative, or zero.
However, the options suggest that the correct answer is positive.
In many practical situations, hydrological data (rainfall, runoff) are positively skewed.
Thus, the coefficient of skewness is positive.

Step 3: Final Answer:
Thus, the coefficient of skewness is positive.
