What is a Pareto chart?
A Pareto chart is also known as a bar graph. In the bar graph, the lengths of each bar represent the frequency or cost (time or money). They are also arranged to the longest bars on the left side of the graph and the shortest to the right. The chart then in this way shows that situations are more significant.
Pareto charts can be used when:
- When there are lots of issues or causes and all you want to do is focus on the most significant.
- When communicating about your data with others.
- When the frequency of problems or causes in a process needs to be analysed.
