When sampling is done without replacement, it means that once an individual is selected from the population, that individual cannot be selected again. This method helps ensure that each member of the population only contributes once to the sample, providing a unique representation of the population. If you're planning a survey or study, sampling without replacement can help avoid bias and improve the accuracy of your results. However, it can also lead to smaller sample sizes more quickly, so keep in mind the total number of individuals you aim to sample!
