Quizplus · Accepted Answer

A smaller amount of variability in the sample means that the sample points are closer to the population mean, resulting in a more precise estimate of the population mean. Conversely, a larger amount of variability in the sample means that the sample points are spread out and can be far from the population mean, resulting in a less precise estimate of the population mean.
