WebA symmetrical distribution occurs when the values of variables appear at irregular frequencies and the mean, median, and mode appear at distinct locations. Skewness is a property of an asymmetric distribution. When shown on a graph, a Gaussian or normal distribution is curved like a bell curve, and the two sides of the graph are symmetrical.
