Question

Quizplus · Accepted Answer

Statistical significance means that the differences found in the sample are unlikely to occur by chance and can be assumed to exist in the population. Choice A is incorrect because it suggests that the differences found in the sample are not unique to that sample. Choice B is incorrect because it suggests that the differences found in the sample can be applied to the entire sample, which may not be true. Choice D is incorrect because it suggests that the differences found in the population are already known and exist in the sample, which may not be true. Choice E is incorrect because it suggests a practical application of statistical significance rather than its actual meaning.
