| Mar 18 at 15:00 | comment | added | whuber♦ | Welcome to CV, Bongo. There's actually no statistical content to this question (not your fault) and its answer will be of little value, because it's just an algebra problem in disguise. Moreover, this definition of "outlier" is not only questionable, it's idiosyncratic: the original formula for the upper boundary was $x_4 + 1.5(x_4-x_2),$ which will indeed highlight a sufficiently large value of $x_5$ for further examination: that is, as an "outlier." I would therefore suggest finding a different resource for learning this material. | |

What relation would it need to satisfy, given the (simplified) formula? Can it satisfy this relation? | |
| Mar 18 at 14:15 | comment | added | Stephan Kolassa | The entire concept of "outliers" is very dubious. I believe I am not saying too much if I state that the consensus here is that "outliers", as defined by this formula, should not, e.g., be blindly removed. The formula you are looking for is a tool to determine which data points should be plotted how in a boxplot - nothing more. | |
