Data symmetrical
WebMar 17, 2024 · If skewness = 0, the data are perfectly symmetrical. But a skewness of exactly zero is quite unlikely for real-world data, so how can you interpret the skewness number? There’s no one agreed interpretation, but for what it’s worth Bulmer (1979) — a classic — suggests this rule of thumb: WebFor symmetric data, the skewness coefficient will be zero; more spread in the data above the mean will have positive skewness coefficient, etc. In the context of quantifying randomness in one RV, three additional parameters are commonly used. They are mode, median, and percentile value of an RV. The mode or modal value of an RV is the value of ...
