    notice how 2 is much smaller than the others? 2 is an outlier, and since we have an outlier, we want to use median

    Which one do you think it is? Mean is the average, and Median is the Middle value of a data set..

    So using Median as @vocaloid said we're going to have to find the median. What is the median in this data set?
