Instructions:

Answer 15 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. The probability that a single unit can pass through a series of process steps free of defects.

2. The risk of accepting the null hypothesis when - in fact - the alternate hypothesis is true. In other words - stating no difference exists when there is an actual difference. A statistical test should be capable of detecting differences that are impo

3. A square matrix of n rows and columns - a technique to control for order effects without having all possible orders; a limited set of orders constructed to ensure that each condition appears at each ordinal position and each condition precedes and fo
