Histogram Interpretation: Skewed (Non-Normal) Right

WebbSkewness is the measure of the asymmetry of a histogram (frequency distribution ). A histogram with normal distribution is symmetrical. In other words, the same amount of data falls on both sides of the mean. A normal distribution will have a skewness of 0. The direction of skewness is “to the tail.”.
