Statistics 101: Sample Mean Proximity to Population Mean.

How close is our sample mean to the actual population mean? How does sample size influence the approximation? In this video we inch towards confidence intervals by looking at how the standard error of the mean influences the sample distribution. We then compare several different sample sizes to see how each size influences the probability that our sample mean is within a certain distance of the population mean. Enjoy!
