![]() It request less experience and knowledge to complete the work. There can be some disadvantages because of the overall simplicity of this process, but it typically allows for a greater understanding on specific questions or needs without the costly processes of qualification that other research methods may mandate.ĥ. This process can also remove the classification errors that can occur in other forms of information collection. It does not require the individuals who are being studied to have specific skills or life experiences to create useful data. Simple random sampling uses common recording skills and standard observation techniques to collect information. It is the easiest method of data collection that is available for research. Then these numbers can be pulled without any foreknowledge of whom they represent, reducing the likelihood that those involved in the research will be going into the data collection process with preconceived notions.Ĥ. The second option for this advantage utilizes random numbers which researchers can then assign to specific individuals or events. The most common option with this advantage is called the “lottery method.” It involves the population group being selected through a random draw, which could be done through the example of having everyone’s name in a hat. Simple random sampling reduces this risk by allowing for multiple types of randomness in the selection of the individuals or circumstances being studied. ![]() When you have a group of researchers pursuing information, then there is the possibility that a conscious or unconscious bias may apply to the application of this data. It provides for multiple randomness types to be included in the research. Then researchers can use this data to apply their findings for everyone within the overall population.ģ. Although there are times when people will purposely misrepresent who they are because they are following their own agenda, this process typically produces accurate information within a small margin of error. It allows the findings to apply to the entire demographic.īecause researchers are randomly pulling individuals for a simple random sampling, there is a strong likelihood that the information received through this process will apply to the entire population. Once that overall population is identified, the only work to do is to randomize which individuals or what circumstances will receive study.Ģ. Because of the structure, it becomes much easier to form a sample group since the only work necessary is to identify the components of the targeted demographic. This demographic is a reflection of the exact sample that researchers wish to interview or study. The random sampling process identifies individuals who belong to an overall population. It is easier to form representative groups from an overall population. List of the Advantages of Simple Random Samplingġ. These are the advantages and disadvantages of simple random sampling you will want to consider when looking at the subjects. The random Ness of this process creates, under most circumstances, a balanced subset which carries the most potential for representing the larger group as a whole. When simple random sampling is used in the field of science, the goal is to conduct randomized controlled tests or create blinded experiments that can extract information from individuals which can then be useful for applying to the entire group. In this example, the population would be the entire workforce, while the sample is random from the hat because every worker has an equal chance of being chosen every time a name is drawn. Investopedia uses the example of a simple random sample as having the names of 25 employees being chosen out of a hat from a company of 250 workers. The goal of collecting information in this way is to provide an unbiased representation of the entire group. Simple random sampling occurs when a subset of a statistical population allows for each member of the demographic to have an equal opportunity of being chosen for surveys, polls, or research projects.
