Sample Mean Distributions is a part of the VCE Specialist Maths topic Probability and Statistics and subtopic Sample Distributions of Means. In this post, we look at how to use confidence intervals for means and the use of simulation to illustrate variations in confidence intervals between samples and to show that most but not all confidence intervals contain µ. A confidence interval is a:
- measure of how much uncertainty is in a sampling method. It describes the probability of a value falling between a set of values around the mean.
What is a Sample Mean?
This video is a very quick overview of how to use the sampling distribution of the sample mean.
The following video describes it with more detail.
