How to mathematically express the smallest non-outlier element in a set?

89 Views Asked by At

For example, in set $S$, what is the smallest element that is not an outlier? (An outlier being either $1.5(Q_3-Q_1)$ greater than $Q_3$ or less than $Q_1$)

What you are asking for is $$ \min \{x \in S \mid x \geq 2.5Q_1 - 1.5Q_3\}, $$ but what you actually need is what you have already written down, as Ethan Bolker points out in the comments: a concise readable description of the element you are looking for.
