A skewness of 0.5 indicates that the data distribution is moderately skewed to the right. In statistical terms, skewness measures the asymmetry of a distribution. A positive skewness value indicates that the tail of the distribution is longer on the right side compared to the left, meaning there are more data points on the left side of the distribution with lower values , while fewer data points have higher values on the right side.
A skewness of 0.5 does not necessarily imply a normal distribution.
Normal distributions have a skewness of 0, meaning they are perfectly symmetrical around their mean. A skewness of 0.5 indicates a deviation from perfect symmetry, with a notable shift toward higher values on the right side of the distribution. Although not perfectly normal, based on other statistical tests and evaluations of the data, a skewness of 0.5 could still suggest a distribution relatively close to normal but with some degree of skewness.
An asymmetry of 0.6 indicates a moderately stronger right asymmetry compared to an asymmetry of 0.5.
It means that the distribution is more skewed, with a longer tail on the right side and fewer data points towards the upper end of the distribution. Similar to a skew of 0.5, this value indicates that the data is shifted to higher values on the right side, but to a slight extent.
Asymmetry between 0 and ±0.5 generally indicates a nearly symmetrical or approximately symmetrical distribution. In statistical terms, this range suggests that the distribution is relatively balanced around its mean, with minor deviations from perfect symmetry.
However, whether an asymmetry in this range is considered “perfectly symmetric” depends on the context and the precision required in the analysis. Typically, skewness near 0 suggests a distribution that is nearly symmetric but may still exhibit slight skewness.
If the skewness is greater than 0, it indicates a right-handed distribution. In such cases, the mean of the data is usually greater than the median, and the tail of the distribution extends toward higher values.
A positive skewness value suggests that the data has a longer tail on the right side and that there are more extreme values on the positive side of the distribution compared to the negative side. This asymmetry often implies that the distribution is not symmetric and may require different statistical treatments or considerations compared to symmetric or asymmetric distributions
