Class SamplingDistributionOfSampleMean

java.lang.Object

com.github.chen0040.si.statistics.SamplingDistributionOfSampleMean

public class SamplingDistributionOfSampleMean
extends Object

Created by xschen on 3/5/2017. A sampling distribution is a theoretical distribution of the values that a specified statistic of a sample takes on in all of the possible samples of a specific size that can be made from a given population. We have not discussed sampling distributions before. Note that we can have sampling distributions of sample means, of sample standard deviations, etc.
