Question

Pareto Chart is used to
1. Identify the critical factor caused for the defect
2. Average number of defects in production
3. Demonstrate the frequency distribution of good quality production
4. Express the bar chart for mathematical analysis

Answer 1

Correct Answer - Option 4 : Express the bar chart for mathematical analysis

Explanation:

Pareto chart:

• It is one of the 7 tools of Quality Management.
• It is a statistical technique in decision making for selection of limited tasks which have significant overall impact.
• It is a series of bars whose height reflects the frequency or impact of problems.
• The bars are arranged in descending order of heights, from left to right.
• Bars on the left are relatively more important than the bars on the right.

Pareto principle:

In terms of quality improvement, large majority of problems (80%) are created by a few key causes (20%).
