ISYE 6644 Simulation Exam 2 Actual Exam
2026/2027 | Verified Questions

Students
This comprehensive actual exam set contains exactly 50 items constructed to reinforce the official ISYE
6644 Simulation course objectives for the 2026/2027 curriculum. The content is organized across four
domains: Random Number Generation and Statistical Testing, Random Variate Generation Techniques,
Input Modeling and Empirical Data Analysis, and Simulation Verification, Validation, and Output
Analysis. The domains cover 12 to 13 questions each drawn from distinct sub-topics, so every item
evaluates a separate body of knowledge with no duplication across the examination. The items are
designed for Graduate-Level, Advanced Practice, and Higher Education engineering and science students
who are working toward the actual exam, and each question is paired with a rationale grounded in official
ISYE 6644 course materials, foundational simulation and operations research textbooks, and current
engineering modeling standards. Working through all 50 questions will reinforce random variate
generation, input modeling, and output analysis skills required for advanced analytical proficiency and
actual exam readiness.
Domain: Random Number Generation and Statistical Testing
1. Which property should a good pseudorandom number generator produce?
A. Numbers that always increase.
B. Numbers that are always the same.
C. Numbers that follow a fixed pattern.
D. Numbers that appear uniformly distributed and independent.
Correct Answer: D
Rationale: A good pseudorandom generator produces numbers that appear uniformly distributed
and independent, even though they are deterministic. This is a core property.
2. Which test is commonly used to check the uniformity of pseudorandom numbers?
A. A regression test.
B. The chi-square goodness-of-fit test.
C. A t-test.
D. An ANOVA.
Correct Answer: B
Rationale: The chi-square goodness-of-fit test checks whether generated numbers are uniformly
distributed. This is a key statistical test.
3. Which test is used to check for correlation or independence between successive random
numbers?
A. An ANOVA.
B. The runs test.
C. A chi-square test.
D. A t-test.
Correct Answer: B
Rationale: The runs test checks for patterns or correlation in the sequence of random numbers.
This assesses independence.

, 4. Which common generator uses a recurrence of the form Xn = (aXn-1 + c) mod m?
A. The linear congruential generator.
B. The inverse transform.
C. The Box-Muller method.
D. The acceptance-rejection method.
Correct Answer: A
Rationale: The linear congruential generator uses the recurrence Xn = (aXn-1 + c) mod m. This is
a foundational pseudorandom generator.
5. Which parameter of a linear congruential generator affects the length of the sequence
before it repeats?
A. The multiplier only.
B. The seed only.
C. The modulus, m.
D. The increment only.
Correct Answer: C
Rationale: The modulus determines the period of a linear congruential generator. A larger
modulus allows a longer period.
6. Which term describes the length of a sequence before it begins to repeat?
A. The mean.
B. The seed.
C. The variance.
D. The period.
Correct Answer: D
Rationale: The period is the length of a sequence before it repeats. Maximizing the period is a goal
of generator design.
7. Which value is the starting point of a pseudorandom generator?
A. The modulus.
B. The multiplier.
C. The seed.
D. The period.
Correct Answer: C
Rationale: The seed is the starting value of a pseudorandom generator. The same seed reproduces
the same sequence.
8. Which desirable property means the sequence can be reproduced for verification?
A. Randomness only.
B. Reproducibility.
C. Unpredictability.
D. Speed.
Correct Answer: B
Rationale: Reproducibility means the same seed produces the same sequence, which is useful for
verification. This is a key property.
9. Which test assesses whether the number of runs in a sequence is consistent with
randomness?
A. The Kolmogorov-Smirnov test.
B. The chi-square test.
C. A t-test.
D. The runs test.
Correct Answer: D
