![]() ![]() Researchers are required to have experience and a high skill level.Ī researcher may not be required to have specific knowledge to conduct random sampling successfully, but they do need to be experienced in the process of data collection. This requires more resources, reduces efficiencies, and takes more time than other research methods when it is done correctly.ģ. This means a researcher must work with every individual on a 1-on-1 basis. When individuals are in groups, their answers tend to be influenced by the answers of others. With random sampling, every person or thing must be individually interviewed or reviewed so that the data can be properly collected. It is a complex and time-consuming method of research. No additional knowledge is given consideration from the random sampling, but the additional knowledge offered by the researcher gathering the data is not always removed.Ģ. Researchers can choose regions for random sampling where they believe specific results can be obtained to support their own personal bias. No additional knowledge is taken into consideration.Īlthough random sampling removes an unconscious bias that exists, it does not remove an intentional bias from the process. ![]() What Are the Disadvantages of Random Sampling?ġ. The generalized representation that is present allows for research findings to be equally generalized. Findings can be applied to the entire population base.īecause of the processes that allow for random sampling, the data collected can produce results for the larger frame because there is such little relevance of bias within the findings. This makes it possible to begin the process of data collection faster than other forms of data collection may allow.ħ. Researchers can also use random numbers that are assigned to specific individuals and then have a random collection of those number selected to be part of the project.īecause random sampling takes a few from a large population, the ease of forming a sample group out of the larger frame is incredibly easy. The first is a lottery method, which involves having a population group drawing to see who will be included and who will not. There are two common approaches that are used for random sampling to limit any potential bias in the data. Multiple types of randomness can be included to reduce researcher bias. Although the simplicity can cause some unintended problems when a sample is not a genuine reflection of the average population being reviewed, the data collected is generally reliable and accurate.ĥ. It also removes any classification errors that may be involved if other forms of data collection were being used. It requires no basic skills out of the population base or the items being researched. This type of research involves basic observation and recording skills. It is the simplest form of data collection. If the researcher can perform that task and collect the data, then they’ve done their job.Ĥ. An item is reviewed for a specific feature. In random sampling, a question is asked and then answered. Researchers could ask someone who they prefer to be the next President of the United States without knowing anything about US political structures. It requires less knowledge to complete the research.Ī researcher does not need to have specific knowledge about the data being collected to be effective at their job. It is a process that builds an inherent “fairness” into the research being conducted because no previous information about the individuals or items involved are included in the data collection process.ģ. ![]() This helps to create more accuracy within the data collected because everyone and everything has a 50/50 opportunity. Random sampling allows everyone or everything within a defined region to have an equal chance of being selected. Because the whole process is randomized, the random sample reflects the entire population and this allows the data to provide accurate insights into specific subject matters.Ģ. This is allowed because the sampling occurs within specific boundaries that dictate the sampling process. Random sampling allows researchers to perform an analysis of the data that is collected with a lower margin of error. It offers a chance to perform data analysis that has less risk of carrying an error. What Are the Advantages of Random Sampling?ġ. Here are some of the additional advantages and disadvantages of random sampling that worth considering. This means random sampling allows for unbiased estimates to be created, but at the cost of efficiency within the research process. This advantage, however, is offset by the fact that random sampling prevents researchers from being able to use any prior information they may have collected. It helps researchers avoid an unconscious bias they may have that would be reflected in the data they are collecting.
