A. Positively skewed
B. Negatively skewed
C. Symmetrical
D. None of these
🧠 Explanation:
The third moment about the mean (skewness) being zero indicates a symmetrical distribution, lacking skew to either side. Studying this concept highlights its role in statistics, a key topic in data analysis. It ensures accurate interpretation of data distributions, critical for fields like economics and research, where symmetry impacts predictive models and decision-making, with implications for statistical accuracy and reliability.
