Quizplus · Accepted Answer

A large sample size reduces the impact of random variation and increases the likelihood of detecting a significant difference. A small variance reduces the amount of noise in the data, making it easier to detect a significant difference. Therefore, a combination of a large sample size and a small variance is most likely to result in a significant outcome for a hypothesis test.
