Common Flaws in Quantitative Studies
The common flaws associated with quantitative studies include inappropriate representation of the target population; requires large sample size to collect data; lack of ability to control the environment; limited outcomes; and complicated data analysis methods (Rahman, 2017).
Inappropriate representation of the target population can interfere with the study’s targeted aims and objectives. In spite of using the suitable sampling plan, representation of the study participants depends on the probability distribution of the available data. This can result in inaccuracy of probability distribution and result in inaccuracy in proposition (Ponto, 2015). Secondly, quantitative studies need large sample sizes and lack of adequate resources may hinder use of adequate sample size when conducting research and hence affect generalization of the study results (Regnault et al, 2018). Moreover, controlling the environment when conducting quantitative research is difficult. As Rahman (2017) explains, when conducting quantitative research, it can be problematic to control the environment where the respondents give answers during the survey or in the questionnaires. The responses are dependent on specific time and conditions existing during that specific time-frame. NURS 4100 Common Flaws in Quantitative nursing Studies
In addition, quantitative researches are associated with limited outcomes due to the structured questionnaires and surveys with close-ended questions. Therefore, the respondents have limited options when it comes to responses and the close-ended questions leads to restricted outcomes delineated within the research proposal (Ponto, 2015). Therefore, the findings do not always represent the actual happenings, in a generalized form. Finally, quantitative studies require complex data analysis methods such as statistical analysis which can be challenging to researchers without knowledge on statistics (Queirós et al, 2017). The requirement to perform efficient statistical confirmation of findings is very challenging within a quantitative study.
