Skewness in statistics measures the
Skewness in statistics measures the asymmetry of a probability distribution, revealing whether the data is skewed to the left or right of the mean.
Positive and Negative Skewness: Positive skewness indicates a longer right tail, suggesting data points are concentrated on the left side of the mean, while negative skewness implies a longer left tail with data concentrated on the right side.
Calculation Basis: Skewness is calculated using the third standardized moment and can be expressed as a coefficient, with positive values denoting right skewness and negative values indicating left skewness.
Statistical Interpretation: Skewness is integral in understanding the shape of a distribution; a perfectly symmetrical distribution has a skewness of zero, while deviations from zero reflect the degree and direction of skewness.
Practical Applications: Skewness finds practical applications in various fields, such as finance, where it aids in risk assessment by identifying the potential for extreme values and influencing investment decision-making based on the distribution of returns.
