If in binomial distribution p ≠ q, the distribution is:___________________?
Correct answer: C. May be positive skewed or negative skewed.
- A. Positively skewed
- B. Negative skewed
- C. May be positive skewed or negative skewed.
- D. None of these
Explanation
The binomial skewness has the sign of q - p. It is positively skewed when p < q and negatively skewed when p > q, so either direction is possible when p ≠ q.
