Question 1

Which type of data is counted in discrete units and cannot be subdivided, such as the number of defective items?

Accepted Answer

Attribute data

Answer

Attribute (discrete) data represents counts of events or defects and cannot take on fractional values.

Question 2

A process capability index of Cp = 1.33 indicates that a process is:

Accepted Answer

Capable with some margin

Answer

Cp = 1.33 means the process spread fits within the specification limits with a reasonable safety margin, generally considered capable.

Question 3

In a measurement system analysis (MSA), 'reproducibility' refers to:

Accepted Answer

Variation caused by different operators measuring the same part

Answer

Reproducibility measures how consistently different operators obtain the same result when measuring the same part with the same gauge.

Question 4

What does the 'sigma level' of a process primarily describe?

Accepted Answer

How many standard deviations fit between the mean and the nearest specification limit

Answer

Sigma level indicates how many standard deviations exist between the process mean and the closest specification limit, reflecting process performance.

Question 5

A run chart is most useful for:

Accepted Answer

Detecting trends or shifts in process performance over time

Answer

Run charts plot data in time sequence, making them ideal for spotting trends, cycles, or shifts before applying control charts.
