A box plot is a type of plot that displays the five number summary of a dataset, which includes: Draw a box from the first quartile (Q1) to the third quartile (Q3) Then draw “whiskers” from the quartiles to the … A residual plot is a type of plot that displays the values of a predictor variable in a … Skewness is a way to describe the symmetry of a distribution.. A distribution … WebbIt clearly follows from this definition that the medcouple always lies between −1 and 1. A distribution that is skewed to the right has a positive value for the medcouple, whereas the MC becomes negative at a left skewed distribution. Finally, a symmetric distribution has a zero medcouple. As shown in Brys et al. (2004), this robust
