Populations and Sampling
A population is the complete collection of all the subjects needed in a study. This can be people, measurements, scores, and so on (Triola & Triola, p. 4, 2006). A population must include every possible subject needed for the study. If not, it is not a population. It can be very difficult to access every subject that is part of the population, especially if the population is very large. Then it would be wise to use sampling.

The result will be your sample size you need to achieve statistically valid results ("Sample Size Calculator," 2004). By having a sample which is the proper size you increase your chances of your sample being representative of the population you are using.
Another way of increasing your chances of developing a sample representative of the population is to use random sampling to choose your subjects for the sample. By using random sampling you are making sure you sample is chosen in such a way that each subject of the population has the same chances of being...
