I'm a programmer, so apologies if this is a bad question. I'm writing some code that needs to detect outliers. I am currently calculating first and third quartiles. In a sample set of data, I have the following numbers:
The median comes out to 179 and the first quartile 178, but since there is no number above the median what should I do? Or what if all the numbers were the same? Is the quartile the median? This is my reference.
