Skewed Data Definition & Meaning

WebWhat Does Skewed Data Mean? Data is considered skewed when it produces an uneven or skewed curve when plotted on a graph. A data set with a normal distribution will have a graph that is symmetrical & shaped like a bell when it is plotted. Skewed data, on the other hand, will always have a “tail” along either of the graph’s sides. In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean.
