The Sørensen–Dice distance is a statistical metric used to measure the similarity between sets of data. Webb8 mars 2024 · Skewness is a measure of asymmetry or distortion of symmetric distribution. It measures the deviation of the given distribution of a random variable from a symmetric distribution, such as normal distribution. A normal distribution is without any skewness, as it is symmetrical on both sides.
