Statistics Flashcards: Evaluating Models With Data And Simulation

Study Evaluating Models With Data And Simulation in Statistics with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

What is the main reason to run many simulation repetitions (for example, $10{,}000$ ) instead of few?

ANSWER

More repetitions reduce random simulation error in the estimated probability. Law of large numbers ensures convergence to true probability.

A survey company claims that

P(\text{supports the proposal})=0.40

for the population. They survey 80 people and find 28 support the proposal. You simulate 100 samples of 80 people each using

P=0.40

. In the simulations, 41 out of 100 samples had 28 or fewer supporters ("as extreme or more extreme" means

\le 28

). Which conclusion is most reasonable?
