Critique of Research


A study was conducted to establish the correlation between critical thinking and performance of students. They comprised of baccalaureate nursing students and were given a "California Critical Thinking Skills Test (CCTST) and the California Critical Thinking Disposition Inventory (CCTDI)".  The National Council Licensure Examination for Registered Nurses (NCLEX-RN) was the performance being measured in relationship to the critical thinking tests conducted. The CCTST was conducted on the entry and exit level. On the CCTST conducted, some of the participants failed while others passed. In the correlation aspect with NCLEX-RN, the results indicated a correlation in the difference between the participants that failed and those that passed the NCLEX-RN, on the CCTST conducted upon entry and exist. Similarly, the students that passed also indicated a higher score in the CCTDI exist test. In both articles, a clear abstract gives the meaning of the study being conducted. Likewise, the abstract given tries to simplify the complex nature of the study into reductionists’ aspects that are well understood.



In the quantitative article, the introduction outlines that the tests conducted were to establish critical thinking in students by use of an NCLEX-RN performance as a means of evaluation. However, upon the tests of CCTST and CCTDI being conducted, the results indicated that some of the students passed while others failed the entry and exit CCTST and CCTDI tests conducted. The final result indicated no difference in the age or gender of the participants in line with the NCLEX-RN performance. On the other hand, the qualitative introduction gives a brief background of the study. In that aspect, it establishes the connection between the background of the study and the subject study on the recent aspect. On the other hand, even though the quantitative article does not have a background of the study, it still gives a clear introduction that explains the subject under study for a clear understanding of what the study entails. This paper will closely look at qualitative and quantitative studies then critique them on the grounds of methods used, data analysis and research questions among others.

Statement of the Problem 

The articles give a slight indication of the problem under study. Therefore, the open statement of the problem leaves room for deductions into what the research tried to look into. The quantitative article seeks to establish the relationship between critical thinking and the NCLEX-RN performance test. On the other hand, the qualitative article seems to look into the performance and success in studies among the Black students. 

Research Question

Both the quantitative and qualitative articles do not give a clear indication of the research questions arising from the study. Therefore, as a critique, the studies in each of the articles try to provide answers to the questions not indicated in the first place, thus misleading the study. 

Literature Review

The quantitative article gives an overview of the literature review in comparison to the study underway. The literature review also relies more on secondary data rather than the primary data. Therefore, this poses as a risk towards validating the primary data used in the quantitative article. On the other hand, the qualitative article also uses literature as a means of inference and comparison to the main data under study. That said, the qualitative article has the tendency of providing more validation and reliability on the information collected as it uses secondary sources as a means of comparison.

Conceptual/Theoretical Framework

It is unlikely for a research to omit the outline of its conceptual framework. In this case, the quantitative article study does not give a conceptual framework that enables the development of a thread towards establishing and interpreting the data, results and the findings. 


The quantitative study involved administering CCTST and CCTDI tests to 218 participants of both genders, different ethics and age. Therefore, the method used entailed non-probability quota sample system aimed towards gaining a sample group of individuals under study. The method hence establishes a clear outline on the identification of the participants and helping towards minimizing errors.. 

Protection of Human Rights

The qualitative article and the quantitative article study did not take any measures towards protecting the rights of the participants understudy. Both of the information on validation was sensitive and thus required and aspect of confidentiality and protection before surfacing to the public. 

Population and Sample

The quantitative data used a non-probability quota sampling technique. Firstly, a population of 218 participants comprising of both gender sought to seek entry scores by conducting CCTST and CCTDI tests. The data was further grouped according to ethnicity and age in correlation to the NCLEX-RN performance. Data Collection and Measurement

The data collected was forwarded for elimination and comparison between that of the national population and the sample of 218 participants. The comparison entailed a 30% minority of the sample compared to 20% of the national population, 93% of the sample that passed the test and 85% national pass rate. 


The procedure entailed measuring the relationship between critical thinking and the NCLEX-RN performance in the entry and exit test scores. 

Data Analysis

The research conducted the NCLEX-RN performance about the tests conducted on both the students that failed and those that passed. In this data analysis, NCLEX-RN performance was the independent variable while the tests CCTST and CCTDI were the dependent variables. The CCTST entry performance was high in those that passed than those who failed the exams. Therefore, the analysis indicated that students who had a high NCLEX-RN performance had better critical skills as compared to those that failed the test. The qualitative research used a deductive and thematic method of data analysis. In this case, the deductive method used indicated a limitation into the research results considering that the method used informed a sampling technique of selecting the exact number of participants required.


The final results of the CCTST and CCTDI tests indicated a correlation between NCLEX-RN performance and critical thinking skills. Therefore, the students that passed the performance tests had a higher critical thinking skills as compared to the learners who failed the NCLEX-RN performance test. On the other hand, the qualitative study did not indicate its findings, but rather went straight to discuss the results of the study. In such a case, one can conclude that the results indicated an error of omission thus questioning the results found. 


The pass and failure scores attributed to the tests performed clearly indicate that indeed there is a correlation between critical thinking and the NCLEX-RN performance. Similarly, for the success in the performance of the black students, the research indicated that there was diverse information to discussion groups and peer study groups to perform and succeed. 

Interpretation of Findings

Both findings are to some extent biased since they involved a sampling approach of choosing the exact number of participants just like the desired participants intended in the study. 


 As much as there is a correlation established between NCLEX-RN performance and critical thinking, shortcomings within the study were revealed. Firstly, the sample comprised of a small number and hence numerous tests were not conducted to establish whether the students would improve their performance or not. Therefore, as a limitation, the study failed in validating the data by administering the same test on several instances. In the same way, the qualitative study indicated some limitations when it came to the accuracy and validation of the data. 

Summary Assessment

Conclusively, the data assessment to some extent was manipulated to meet the desired results. The data manipulation arises from the overreliance on secondary data as examined in the literature review. Therefore, it can be clearly established that both studies discovered positive correlations between the variables under study.
