Question 202537: the interquartile range irq is the best measure of variation when data distribution is skewed right true or false?
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! Resistant statistics: median, mode, quartiles, IQV. These statistics do not change in the presence of outliers.
Nonresistant: all value based statistics are non-resistant statistics (mean, variance, standard deviation, coefficient of variation, correlation coefficient). These statistics’ values are affected by the presence of outliers.
