Please help. Thank you in advance. You have just completed a simulation in which you attempted to construct a random sample that was representative of your chosen population using EPSEM techniques. The issues you encountered are similar to those that social scientists have to deal with on a regular basis: the integrity of the experiment depends on a random and representative sample. How well can you answer the following question? Why is a "random sample" not random in the popular sense of the word? What is another term social scientists use for these kinds of samples? .
