There are a number of reasons why it is often difficult to measure or count all the individuals within a population, including time and money constraints, a large number of individuals, or difficulty in accessing some areas. If it is not possible to measure or count all the individuals within a population, we must select an area of the population to sample. Because individuals are rarely evenly distributed within an area, it is important to sample randomly to ensure that we get a true representation of the population. Random sampling statistically measures a subset of individuals selected from a larger group or population to approximate a response from the entire group. Unlike other forms of surveying techniques, simple random sampling is an unbiased approach to garner the responses from a larger group. Because individuals who make up the subset are chosen at random, each individual in the larger population set has the same probability of being selected.
