Analysis of Cause and Effect, Flow Chart, Pareto Chart, and Run Chart

This assignment provides a comprehensive analysis of several statistical tools. The solution includes an examination of a cause-and-effect diagram, addressing factors contributing to exam failure, and a flow chart detailing the process of getting to school or work, highlighting potential improvements. A Pareto chart analysis is also included, identifying key areas requiring attention, such as inattentive service and other related issues. Additionally, the assignment presents a scatter diagram demonstrating a positive correlation between overtime and the number of rejects, suggesting a need to minimize overtime. Finally, a run chart is analyzed, indicating a decline in the reject percentage over a specific period. This assignment is designed to help students understand statistical analysis and the application of different charts in data interpretation and decision-making.

Answer #1: Cause and Effect Diagram
a. Failure to earn an A on an examination
b. You consistently arrive late for class or work.

c. You consistently slice when hitting a golf ball with your driver.
d. Your table lamp fails to light when you turn the switch on.

Answer #2: Flow Chart for Getting to School or Work
Considering the above flow chart, it can be stated that there are no major improvements that
can be made. However the improvements in few more minutes can be made if there is no
provision for hitting the snooze button that delays the individual for three minutes on
average.

Answer #3: Pareto Diagram
Based on the Pareto chart above, the inattentive service requires quick attention. The other
four important areas to be handled afterward are overprice, cold food, dirty silverware and
dirty dishes.
Answer #4: Scatter Diagram
Based on the given data, above scatter diagram has been constructed. A positive correlation
exists between both the variables. This shows that the increase in the overtime simultaneously
increases the number of rejects. Therefore, one suggestion from this graph can be made is,
company should avoid employing overtime as much it can.

Answer #5: Run Chart
The above run chart developed based on the data given, it can be said that the reject
percentage has declined over the month from January to December.
