Skewness less than 1
WebbA conventional differential line (DL), commonly used on typical digital circuit boards for transmitting high-speed digital data, has fundamental limitations on the maximum signal bandwidth (~10 GHz), mainly due to signal skew, multiple line coupling, and EM interference. Therefore, to support super-high-speed digital data transmission, especially … Webb12 jan. 2024 · The skewness is moderate. If the skewness is lower than -1 (negatively skewed) or greater than 1 (positively skewed), the data is highly skewed. Your Data …

Generally, if the distribution of data is skewed to the left, the mean is less than the median, which is often less than the … WebbKurtosis. In probability theory and statistics, kurtosis (from Greek: κυρτός, kyrtos or kurtos, meaning "curved, arching") is a measure of the "tailedness" of the probability distribution of a real -valued random variable. Like skewness, kurtosis describes a particular aspect of a probability distribution.
