Descriptive research is a method of research that provides a comprehensive account of the subject of interest. The results of descriptive research may be used to inform other research methods or aid future studies of the same issue. The descriptive approach is often used to help solve real-world problems in various fields. Its advantages are numerous and include the following:
In descriptive research, the method of random sampling is used. The problem with random sampling is that a sample does not always represent the population. The resulting data is prone to sampling errors. For this reason, survey research typically involves polls and questionnaires. When conducting a survey, it is important to use a combination of open-ended and closed-ended questions. Listed below are some ways that random sampling is used in descriptive research.
This type of study involves observing people doing a task and noting down the activities that they engage in. Observational sampling is important in descriptive research because it can prevent biases when conducting interviews. It is also useful for planning future workplace designs. The downside of this research type is that the quality of the observations is often limited, especially if the tasks are complex or time-sensitive.
There are two types of systematic sampling: linear and random. While systematic linear sampling involves a random number generation, the former focuses on selecting n units from the population. Random number generation consists in choosing a random number and adding it to the population’s sample. The latter involves repeating the process with the remaining population members. The results can be used to create a model of the people. This is a common method in descriptive research.
Compared with random sampling:
Compared with random sampling, systematic sampling is faster and easier to use with large sample size. It can easily number the participants and allows for a large sample size. However, systematic sampling can also introduce bias and poor survey results. For these reasons, it should be used sparingly. In addition, systematic sampling is an effective method for conducting descriptive research. You should always make sure that your sample is representative of the population.
When it comes to descriptive research, one of the most common research sampling methods is judgement sampling. This method is useful for several reasons, but its main advantage is that it allows researchers to select the best units for their study, thereby enabling them to answer research questions. It is particularly useful when the population of interest is small and desirable teams have a relatively low frequency. Probabilistic sampling is not practical for small people. Moreover, judgment sampling ensures that researchers do not select sample members based on their background or education.
Advantages of judgment sampling:
Another advantage of judgment sampling is its relevance. It is more accurate than probability sampling, as the researcher can select a sample based on his professional judgment and knowledge. However, judgment sampling has some drawbacks, so researchers must use this method with care. This method is also prone to researcher bias. This means that judgment sampling should be used with caution, however, because it tends to skew the results.
