APCSP Simulation Models 2

Question 1

A climate scientist uses a simulation to predict temperatures over 100 years. Which factor most directly affects the simulation's accuracy?

Accepted Answer

The quality and completeness of the real-world data used as inputs

Answer

The programming language used to code the simulation

Answer

The speed of the computer running the simulation

Answer

The number of scientists reviewing the results

Question 2

In a traffic simulation, cars follow simplified rules rather than mimicking every driver behavior. This is an example of:

Accepted Answer

Abstraction used to make the simulation manageable

Answer

A bug in the simulation

Answer

Data bias introduced by the programmer

Answer

Parallel computing applied to modeling

Question 3

A simulation produces different results each time it runs because it uses randomly generated inputs. This type of simulation is called:

Accepted Answer

Stochastic

Answer

Deterministic

Answer

Iterative

Answer

Sequential

Question 4

Why might a scientist run the same simulation hundreds of times with different random seeds?

Accepted Answer

To collect a range of outcomes and analyze the distribution of results

Answer

To find the fastest possible outcome

Answer

To ensure the simulation code has no bugs

Answer

To reduce the file size of the output data

Question 5

A flight simulator accurately models aerodynamics but ignores weather turbulence. Which statement best describes this simulator?

Accepted Answer

It models some real-world aspects while abstracting away others

Answer

It is completely invalid because it omits turbulence

Answer

It is a deterministic simulation because it has no randomness

Answer

It cannot be used to train pilots because of the omission

Question 6

Which of the following is a LIMITATION of using simulations instead of real-world experiments?

Accepted Answer

Simulation results depend on the accuracy of the underlying model and assumptions

Answer

Simulations always take longer to run than real experiments

Answer

Simulations can only model physical phenomena, not social ones

Answer

Simulations cannot use mathematical equations

Question 7

A student simulates rolling two dice 10,000 times to estimate the probability of rolling a sum of 7. Why is a large number of trials important?

Accepted Answer

A larger sample size produces results closer to the true theoretical probability

Answer

More trials make the program run faster

Answer

Fewer trials would cause the program to crash

Answer

More trials eliminate all randomness from the simulation
