Since this is the case, sampling without replacement is approximately the same as sampling with replacement because the chance of picking the same individual more than once with replacement is very low. Create a cluster sample by considering each state as a stratum (group). The type of data that has clear spaces between values is discrete data. For the purpose of analysis, data are presented as the facts and figures collected together.
