### **Multiple Choice Questions Week 4** **What does a \"shift\" in a run chart indicate?** - A\) 5 or more sequential data points all increasing or decreasing - B\) A series of points on one side of the median line - C\) 6 or more consecutive data points above or below the median - D\) An obvious outlier from the remaining points **Answer:** C) 6 or more consecutive data points above or below the median *Explanation: A \"shift\" indicates that there are 6 or more consecutive data points on one side of the median, suggesting a potential change in the process.* **What is considered an \"astronomical point\" in a run chart?** - A\) 5 or more sequential data points all increasing or decreasing - B\) A clear outlier from the remaining points - C\) The total number of runs - D\) 6 or more consecutive data points above or below the median **Answer:** B) A clear outlier from the remaining points *Explanation: An \"astronomical point\" is an obvious outlier that stands apart from the rest of the data points, identified by the team based on their judgment.* **In a run chart, what does a \"trend\" represent?** - A\) 5 or more sequential data points all increasing or decreasing - B\) A series of points on one side of the median line - C\) 6 or more consecutive data points above or below the median - D\) An obvious outlier from the remaining points **Answer:** A) 5 or more sequential data points all increasing or decreasing *Explanation: A \"trend\" in a run chart is identified when there are 5 or more sequential data points that are either all increasing or all decreasing, which may indicate a systematic change in the process.* **How is the \"number of runs\" in a run chart determined?** - A\) By counting the total number of data points above the median - B\) By identifying the clear outliers in the data - C\) By counting the number of times the data line crosses the median plus one - D\) By evaluating the distance between the highest and lowest data points **Answer:** C) By counting the number of times the data line crosses the median plus one *Explanation: The \"number of runs\" is determined by counting the number of times the data line crosses the median line and adding one. This helps in evaluating the randomness of the data.* **Which rule would be applied if there are 5 or more data points that increase or decrease sequentially in a run chart?** - A\) Shift - B\) Trend - C\) Number of runs - D\) Astronomical point **Answer:** B) Trend *Explanation: A \"trend\" is identified when there are 5 or more data points that increase or decrease sequentially, indicating a potential systematic change in the process.*
