WebFor skewness, if the value is greater than + 1.0, the distribution is right skewed. If the value is less than -1.0, the distribution is left skewed. For kurtosis, if the value is greater than + 1.0, the distribution is leptokurtik. If the value is less than -1.0, the distribution is platykurtik. What is skewed by a few very high or low values?

WebIn a symmetric bell curve, the mean, median, and mode are all the same value. But in a skewed distribution, the mean, median, and mode are all different values. A skewed data distribution or bell curve can be either positive or negative. Positively Skewed Distribution. A positively skewed distribution means that the extreme data results are larger.
