This is also a general rule of
business.
Consider
IBM-
80% of their
profit comes from only 20% of their customers(the larger
customers)
20% of their profit comes from the other 80% of their customers (the smaller ones)
Consider E2-
20% of the writeups have garnered about 80% of the total
votes that have been used while
80% of the
writeups have fewer votes (either way) and only have 20% of the total votes used
This rule can apply to many other
statistical
aspects where there is a
human interest or
business factor that directly influences two
quantities such as those shown above. It is only a
generalization to
remind people where their priorities (are|should be).
