Sampling with replacement A researcher is interested in drawing a sample of potential voters from a population of 10 individuals. She settles on a sample size of 5, and sends out random invitations to 5 of the voters, by picking their names randomly from a list. How many possible samples could she draw from this population? Sampling without replacement The researcher realizes that she made a mistake! She accidentally asked the selected some of the same voters more than once....

Sometimes the results from a restricted sample may not be the same as the results from a larger population. For example, the results from the analysis on patients in a hospital may be significantly different from the results from a sample taken from the general population. Therefore, the results from analyzing a sample from the patients in a hospital may be signficantly different from the results from a sample taken from the general population. This phenomenom is called A Simpson's...
