WebGraph A is skewed right, while Graph B is skewed left. With right-skewed graphs, the mean always comes to the right of the mode (i.e., the peak). ( Asitgoes /Wikimedia Commons) [ These features ultimately make it difficult to assign a typical value as there is no clear center point on a right-skewed graph. Web9 de mar. de 2024 · In statistics, a negatively skewed (also known as left-skewed) distribution is a type of distribution in which more values are concentrated on the right side (tail) of the distribution graph while the left tail of the distribution graph is longer. While normal distribution is the most commonly encountered type of distribution, examples of …
