An outlier is a value that is lies outside the other values in a set of data. This value could either be very big or very small. In this case, your outlier is 2. The answer for this one would be the range. With the outlier, your range is 10 and without it, it would be 4. The jump can be considered significant and which is usually the reason why outliers are removed from the data set.
