If the skewness value falls between -0.5 and 0.5, the data is almost symmetrical. When the skewness is between -1 and -0.5 (indicating a negative skew) or between 0.5 and 1 (indicating a positive skew), the data is somewhat skewed. If the skewness is less than -1 (showing a strong ...

A distribution with zero skewness is perfectly symmetrical, meaning the left and right tails are of equal length. In this case, the mean, median, and mode coincide at the same point. It is important to analyze skewness because it provides insights into the underlying characteristics of the data...
In probability theory and statistics, kurtosis (from the Greek word κυρτός, kyrtos or kurtos, meaning bulging) is any measure of the "peakedness" of the probability distribution of a real-valued random variable.[1] In a similar way to the concept of skewness, kurtosis is a descr...

Skewness measures the asymmetry of a distribution. Skewness indicates the direction and degree to which the data deviates from a symmetrical bell curve. A distribution with zero skewness is perfectly symmetrical, meaning the left and right sides of the distribution are mirror images. Positive ...
