Probability Sampling Method - Coursework Example

It is important to eliminate biased acts in the process. Using a method that freely involves any of the students will reduce biases in the manner of selecting students for the survey. In probability sampling, there is previous knowledge of the probability that a student participates in the survey (Maxfield and Earl, 223). The sample collected from the chosen respondents reflects the general feeling of the total population from which the samples originate.

Probability sampling has advantages over other methods of survey. The first advantage is that it offers a better representation of the population than the other methods of survey. The manner of choosing the participants allows for proper representation of the people in the population. Through this, therefore, the method avoids biases that could occur in choosing participants. The second advantage is that probability sampling allows the sampler to estimate the accuracy of the survey. By concluding probability theory, it is possible to estimate the success or failure of the method accurately (Maxfield and Earl, 226). Read More
