Data that is more than 1.5 times the interquartile range from the quartiles?

Outliers


Why do you multiply the interquartile range by 1.5 to find the outlier?

By definition a quarter of the observations are below the lower quartile and a quarter are above the upper quartile. In all, therefore, half the observations lie outside the interquartile range. Many of these will be more than the inter-quartile range (IQR) away from the median (or mean) and they cannot all be outliers. So you take a larger multiple (1.5 times) of the interquartile range as the boudary for outliers.
