Apr 24, 2014 at 18:05 | comment | added | whuber♦ | You're right, but I think you have omitted to mention a crucial consideration: that the median and hinges ("quartiles") are resistant to outliers. A most basic description of a batch of data will tell us a typical value (median), indicate how much it is spread above and below that value (the hinges), and give us a sense of just how far out the data really do go (the extremes). The mean and standard deviation do not serve the first two purposes for general data exploration because they are too heavily influenced by even one outlier. | |
