Topic 16. Sampling Distributions 1: Proportions. Overview. You have been studying probability and probability distributions.These ideas arise in the practice of statistics because sound data collection strategies involve the deliberate introduction of randomness.. Therefore, drawing meaningful conclusions from sample data requires an understanding of properties of randomness.

The sampling distribution of the sample mean is normal with mean and standard deviation . Thus, both sampling distributions will be centered at 8 inches, but the sampling distribution of the sample means when n = 15 will have more variability than the sampling distribution of sample means when n = 50.
