Suffern, NY | Statistics "The top 1% each used an average of 120.94GB, nearly double the 66.03GB used by the next percentile. The average customer used 6.19GB, although removing the heaviest 10% of users cuts that to 2.35GB."
Which average are they using for that 6.19GB/2.35GB (There are 3 types of measures called "average")?
The one that everyone thinks of as "average" is the total of all usage divided by the number of users. There is also the usage value that half of the users exceed and half are less than. The third is the usage value that the largest number of users measure.
By not identifying your methodology, you can give any impression you want by choosing the method that gives the best number for your purpose (Check out the classic book on this topic - "How to Lie with Statistics" by Huff). I'd be interested in seeing the actual numbers/graph (a graph is mentioned in the article but not included).
No matter what you measure you are going to have those who use the most. The question is if that usage is "excessive" or just is portrayed as such due to being the largest values. |

The third is the usage value that the largest number of users measure. No, Only the Mean Value is the Average.
The point where 50% of the values lie above and 50% below is the Median.
The point where the largest occurrence of values occur is the Mode.
Median and Mode are not substitutes for Average.
