2. The difference between observed measurements and a "true" value obtained from a master or gold standard
3. Different levels of variability in different operating regimes, resulting from warm-up effects, environmental factors, inconsistent operator performance
4. None of the above

Q3. The ______________ sum of squares measures the variability of the observed values around their respective treatment means.

2. error
3. interaction
4. total

Q4. Which of the following statements is NOT true about charting variation?

2. A histogram helps understand process performance
3. A histogram is sufficient to chart variation
4. Run charts display process performance over time

Q5. Two factors are said to be orthogonal when:

1. they are correlated, that is, they cannot vary independently
2. there are equal numbers of participants in all groups
3. they are uncorrelated, that is, they vary independently
4. there is a single control group, with which all the other groups can be compared

Q6. Quality control is:

1. evaluating overall project performance on a regular basis to provide confidence that the project will satisfy the relevant quality standards
2. taking action to increase the effectiveness and efficiency of the project so as to provide added benefits to both the performing organization and the project customer
3. assuming the production of goods that meet the highest standards of luxury
4. identifying which quality standards are relevant to the project and determining how to satisfy them
5. monitoring specific project results to determine if they comply with relevant quality standards and identifying ways to eliminate causes of unsatisfactory performance
