![]() ![]() ![]() In such cases, the arithmetic mean would again, not be the best representation of the average value to use. In this particular case, even if there were very small outliers (say if 2 out of the 47 people actually earned only $5,000 a year), they would not significantly affect the result, but in different scenarios they could have a significant effect. In contrast, the median, since it is exactly in the middle of the values, isn't affected by either very large or very small values, and better represents the data since the median is what 94% of people in the room earn. Clearly this is not a good representation of what the average person in the room earns. Find the arithmetic mean of these two numbers to find the medianĮven though there are only three people who earn more than $55,000 in this example, and they comprise only 6% of the people in the room, because they earn vastly more, they skewed the mean income such that the value is almost 12 times more than what 94% of the people in the room earn.
