The median is a good way to find the middle of the data and ignore outlying data points that might skew the average result. It reflects the middle of the typical values of the data. The mean might be more useful if the average value of the entire set of data is important. The statist...

The mean and the median both reflect the skewing, but the mean reflects it more so. The histogram for the data: 66; 77; 77; 77; 77; 88; 88; 88; 99; 1010, is also not symmetrical. It is skewed to the right.Figure 3The mean is 7.77.7, the median is 7.57.5, and the mode ...
and younger than 37. The median is used where strong outliers may skew the representation of the group, such as with incomes. If you have one person who earns $1 billion a year and nine other people who earn under $100,000 a year, the mean income for people in the group would be ...
We find that the mean is being dragged in the direct of the skew. In these situations, the median is generally considered to be the best representative of the central location of the data. The more skewed the distribution, the greater the difference between the median and mean, and the ...

The median is very useful for describing things like salaries, where large figures can throw off the mean. The median salary in the U.S. as of 2012 was $51,017. If an average was used, those American billionaires could skew that figure upwards. Let’s say you wanted to work for a ...
Mean income (the total of all values divided by the number of values in a dataset—otherwise known as the average) is the primary mathematical value for making comparisons. However, having a large number of high-earningone-percentersor low-income people in a region can skew the end result ...
