To find the median of the data we need to order it first. The order data is:
193, 255, 339, 339, 349, 386, 417, 448, 471, 486, 487, 500, 512, 513, 3200
Now, the median is the central data of the set, in this case the median is the 8th data, therefore the median is 448.
Now we notice that the median is less than the mean, this comes from the fact that the median is the central value of the set while the mean is the average of the data set; this means that the median does not take into account the large values of the data set.
