  1. A quality team uses a scatter diagram and finds a correlation coefficient of +0.92. What does this indicate?

    Answer: A strong positive relationship between variables

    A correlation coefficient of +0.92 indicates a strong positive relationship, meaning as one variable increases, the other tends to increase as well.

  2. In a fishbone (Ishikawa) diagram, the 6M categories include Machines, Methods, Materials, Measurement, Mother Nature, and:

    Answer: Manpower

    The traditional 6Ms in a fishbone diagram are Machines, Methods, Materials, Measurement, Mother Nature (Environment), and Manpower (People).

  3. Which run chart pattern indicates a potential special cause when seven or more consecutive data points fall on the same side of the median?

    Answer: Run

    A run of seven or more consecutive points on one side of the median is a non-random signal suggesting a special cause in a run chart.

  4. A team wants to collect data on defect types during production. Which tool is BEST for tallying frequency of occurrence in real time?

    Answer: Check sheet

    A check sheet is designed for real-time structured data collection, allowing team members to tally occurrences as they happen.

  5. The 80/20 rule in quality improvement means that approximately:

    Answer: 80% of effects come from 20% of causes

    The Pareto Principle (80/20 rule) states that roughly 80% of problems or effects result from 20% of the causes.

  6. Which tool would BEST help a team understand the sequence and flow of a process before identifying improvement opportunities?

    Answer: Flowchart

    A flowchart visually maps process steps and decision points, helping teams understand how a process works before seeking improvements.

  7. During a brainstorming session, a team member begins critiquing an idea as it is presented. What is the CORRECT action for the facilitator?

    Answer: Remind the group that no criticism is allowed during brainstorming

    A core brainstorming rule is to defer judgment; the facilitator should remind participants that criticism is not permitted during the idea-generation phase.
