The only way to test your knowledge baseline is by practicing. Every single practice problem of the QCI CSSBB Primer should be answered and understood before doing the test.
ASQ asks trick questions. Example:
What is the standard deviation of the following sample: 3.2, 3.1, 3.3, 3.3, 3.1
a. 3.2
b. 0.0894
c. 0.1
d. 0.0498
Solution (extracted from the CQE Primer Solution Text): “In more uncomplicated times, the world understood that a sample was determined by using n-1 in the divisor, and it was assumed that the sample was taken to make some inference about a population. However, an errata change after the 1984 test publication stated that this assumption could not be made. The prediction or inference regarding a population must be spelled out in the question. Otherwise, the sample is to be considered a complete data set.”
