Statistics question: Does range include outliers

Recommended Posts

If there's an outlier in my data set e.g. 3, 5, 4, 3, 99 (99 is the outlier):


is the range 99-3 = 96

or is it 5-3 = 2 (excluding the outlier)?


any help would be much appreciated i have a test tomorrow lol!!


The outlier is a piece of data that is distant from all other observations, and therefore should be excluded from the data set. And because it's excluded, so you cannot use it to compute the range for the data set. So it is 5-3=2.
