WebbThe median can be found by arranging the data in an ascending order, and then finding the middle value. Ex. Median of: 1,3,4,5,8,9,9 is 5, since 5 is the number in the middle. If there are two numbers in the middle, average them (add and divide by 2). To find the mode, search for the value which occurs most frequently. WebbIn a skewed distribution, the mean will differ from the median in the direction of the skew (i.e., the direction of the longer tail). For highly skewed distributions, the mean can be pulled so far in the direction of the skew that it is no longer a good measure of the central tendency of that distribution.
