Zero skew (or zero skewness) refers to a symmetrical, bell-shaped distribution where the probability of observing a value to the left or right of the mean is equal. This means that the distribution is balanced, with no long tail on either side of the mean. In other words, both sides are mirror images. In a zero-skewed distribution, the mean, median...
Positive skew (also known as right skew) occurs when the data is not symmetrical around the mean, forming a long tail on its right side. This means that most of the distribution's observations are concentrated to the left of the peak. The presence of positive skewness can have several implications. In a right-skewed distribution, the mean is larger...
With negative skew (also known as left skew), the left tail of the distribution extends to the peak’s left. This means that most of the observations are clustered to the right side. As a result, a negatively skewed distribution is not symmetrical around the mean, with a long tail on the left side of the peak. In a negatively skewed frequency distri...
Calculate the skewness of a sample or a population using formulas and examples. Learn what skewness is, how to interpret it, and how it affects statistical analysis.
Apr 27, 2024 · This skewness calculator finds both the skewness and kurtosis of a dataset and interprets these values, telling you how skewed or peaked your distribution is.
