Question 1

A histogram shows data that is skewed to the right. This most likely indicates:

Accepted Answer

There is a natural lower limit preventing values from going below a threshold

Answer

Right-skewed data often results from a natural lower boundary (like zero), which clusters data on the left and stretches the tail to the right.

Question 2

Which of the following BEST describes the purpose of a control chart's upper and lower control limits?

Accepted Answer

They identify the boundaries of common cause variation

Answer

Control limits are statistically calculated boundaries representing the expected range of common cause variation in a stable process.

Question 3

An affinity diagram is MOST useful when a team needs to:

Accepted Answer

Organize a large volume of ideas into natural groupings

Answer

An affinity diagram organizes large amounts of qualitative data or ideas into logical groupings based on natural relationships.

Question 4

In the Plan-Do-Check-Act (PDCA) cycle, what activity occurs during the 'Check' phase?

Accepted Answer

Evaluating results of the implemented plan against expected outcomes

Answer

The Check phase involves comparing actual results to expected outcomes to determine whether the plan achieved its goals.

Question 5

A team discovers that 3 of 15 defect categories account for 78% of all defects. This finding is BEST visualized using a:

Accepted Answer

Pareto chart

Answer

A Pareto chart displays defect categories in descending order of frequency with a cumulative percentage line, making it easy to see which few categories dominate.
