Lesson 2: Fundamentals of Sampling Design
8 Simple Random Sampling < Back | Next >
The most common type of sampling design is the simple random sampling. In fact, most statistical equations assume that you have conducted a simple random sample. Using this approach every possible combination of experimental units has an equal and independent chance of being selected. This approach implies that two conditions must be met first that every experimental unit has an equal chance of being selected and second that the outcome of one selection is not dependent upon the outcome of another selection. You could simply do this by assigning every unit a number and then randomly pick x numbers for sampling.
