Pareto analysis states that 80% of a project’s results are due to 20% of the inputs, and 80% of problems can be traced to 20% of the causes.

This post offers reasons for using logarithmic scales, also called log scales, on charts and graphs. It explains when logarithmic graphs with base 2 are preferred to logarithmic graphs with base 10.
