Critical Analysis: Why and How to do a Critical Analysis

 Author: Ushna Nawaz

Critical Analysis

Critical analysis is a way of pinpointing the strengths and weaknesses of an article. One can provide suggestions to the author by critically analyzing the presented work. In critical analysis, we evaluate the themes (content), structure/organization as well as various components of the article.

Critical analysis is different from an article review as critical analysis is done by an expert in the field and evaluates the work from the critical and technical point of view; whereas, an article review can be done by an amateur. Article review is based on subjective opinion and critical analysis is more of objective nature.

Why Critical Analysis is Required?

Critical analysis provides a system of keeping checks and balances. It acts as feedback and allows strengthening of the work by highlighting the limitations and flaws of the study. It helps to identify which part of the study needs improvement. Moreover, it helps to evaluate the quality of the study, identify the strengths and weaknesses of the study, promote intellectual rigor, enhance the objectivity of the study, enhance communication skills, encourage continuous improvement, and promote the advancement of knowledge. The process of critical analysis is usually used before publishing a study or an article and published articles are also analyzed.

Elements of Critical Analysis

In critical analysis, one examines various components of the article and highlights which component is included or excluded within the article. Usually, when people initiate to analyze the article they find it difficult to start because, in the beginning, they have less knowledge about the requirements of critical analysis. So, the following explanation probably helps those individuals who are at the initiating stage of critical analysis.

Note. It must be noted that the article explained the general guidelines; however, the standards may change across different journals and study types.

Abstract

The first component of an article is the abstract. The standard word count of this component is 200, i.e. abstract’s length should not be more than 200 words. The examiner must consider the following points while critically analyzing an article or study:

·         If the main purpose and aim of the study are stated

·         Does the abstract mention the research question(s) or hypotheses

·         Does the abstract include the method, sample selection, and sample size

·         If the abstract mentioned the main results, conclusions, and recommendations

Introduction

The introduction should start by explaining the purpose of the study to set the stage for the study. It should include the rationale and significance of conducting the study. The introduction of a research study should be written in simple language, in the present tense, and should include the purpose, rationale for conducting the study, background information, current state of knowledge, and the gap the study aims to fill. It should contain three specific themes: providing essential background information related to the subject matter, stating the research hypothesis, and focusing on the topic.

Moreover, the introduction should include past literature with keywords, state the purpose of the study with a rationale, and narrow down from unsolved issues to the gap the study aims to bridge. The conclusion should conclude with an obvious purpose and objective, helping readers focus on important aspects of the study. This approach helps readers focus on the study's objectives and contributes to the overall success of the research.

Literature Review

Literature review plays a major role in developing a research question and assists in determining the suitable methodology for the collection of data. A literature review should be from recent origins, ideally less than five years old, and should include a variety of sources arranged chronologically or by subject matter. The review should be mixed of previous studies related to the research question, with some supporting the author's point of view and others not. It should begin with an introduction identifying keywords and related information, and include the strengths, limitations, and comparisons with other studies. The review provides an overview of the research study, including key author, prevailing theories, and methodologies. Primary sources are more favorable in literature reviews.

In short, within the literature review section, we check,

·         If all the included references are related to the problem of study

·         If the study includes more primary sources with fewer secondary sources

·         If the gap among previous studies is identified; if the former studies are compared and contrasted

·         If the literature review section ends with a concluding paragraph or statement and relates the literature to the current study

·         The literature review discussion develops a theoretical or empirical ground for the hypotheses

·         If the studies included are less than five years old or not

Theoretical and Conceptual Framework

It is also required to determine if the researcher added some relevant theory. The theoretical framework is a guide for a study, identifying conceptual relationships and guiding empirical observation. It helps explain research findings and understand natural phenomena. Although not all studies are based on a theory or conceptual model, every research study has a framework.

The conceptual framework is a structure that explains the natural progression of a study's phenomenon, linking concepts, important theories, and empirical research. It promotes and organizes the researcher's knowledge related to the study. The conceptual framework describes the relationship between the main concepts of a study and is used when existing theories are insufficient to create a structure for the study.

In short, we need to identify the included theories and their relevancy with the problem being investigated, and the conceptual framework, i.e. if the researcher provided a clear link between the key concepts of the study.

Variable and Hypotheses

A hypothesis is a statement that explains the relationship between two or more variables, providing an explanation and answer to the research question, and is used to predict the study's outcome, providing direction for data collection, analysis, and interpretation.

A critic needs to examine whether the researcher mentioned the variables explicitly provided the relationship between variables in the hypotheses and added only those variables in the hypotheses that are supposed to be investigated in the current study. Under the hypotheses section, the critic determines

·         If the researcher included certain research questions or hypotheses to be investigated   

·         If  each hypothesis explains an expected relationship or difference

·         If required, are the variables defined operationally or directly

·         If the stated hypotheses are testable or not

Ethical Consideration

It is worthwhile to notice that the researchers need to follow certain standards to conduct research. The researcher needs to get approval from the research committee before conducting the study and from the participants before collecting data. At each step, the researcher needs to follow a certain ethic such as not harming the participants. Therefore, under this section, we determine the following,

·         If the researcher received approval from Ethical committees or institutional review boards

·         If the researcher followed four fundamental ethical principles, i.e. justice, beneficence, autonomy, and non-maleficence.

Justice is concerned with treating everyone equally and ensuring that no one is given preferential treatment. Autonomy implies that a man or woman can freely choose to participate in a research study. Non-maleficence is defined as not harming and preventing harm occurring to members. Beneficence is interpreted as the benefit of research to the participant and society as a whole.

Methodology

The methodology section includes multiple sub-headings and each heading needs to be evaluated critically.

Research Design and Procedure

Research design is a strategy used by researchers to answer questions and test hypotheses, specifying the method and procedure for collecting and analyzing information, emphasizing a systematic methodology, and serving as a blueprint for data collection, measurement, and analysis. The critic determines if the selected design is suitable for testing the hypothesis and if the procedures are defined adequately enough that others can replicate the study, i.e. if the procedure is defined clearly and in detail.

Sample and Sampling Method

In a research study, sample selection and sampling methods are crucial. Researchers must identify the target population, select participant criteria, and provide evidence of sample selection and the number of participants invited.

Under this section, the critic needs to determine the following,

·         If the researcher explicitly defined the sampling strategy

·         Is the sampling strategy appropriate for the current study

·         If the participants are appropriate and can provide data related to the current research problem

·         If the researcher explained the inclusion and exclusion criteria

·         If the researcher explicitly mentioned which sampling strategy or tool he used to determine the number of participants

·         If the number of participants is mentioned in the study

·         If the population's size and major characteristics are clearly described

·         If the researcher avoided using volunteers

·         If the sample size meets the suggested guideline for minimum sample size appropriate for the research method

Data Collection Method

In research, the researcher can use a variety of tools for data collection including questionnaires and interviews. In this section, the critic needs to determine, if the researcher clearly and concisely explained which method and tool is used for data collection. Moreover, it is required to identify the procedure of data collection.

Instruments

The selection of instruments is an important part of the study and needs a lot of searching. In this section, the critic focuses on the following features,

·         Is the justification provided for the choice of tools (or measurements) applied?

·         Is the purpose and content of each instrument described?

·         Are the tools suitable for evaluating the variables that are being measured?

·         Is there proof offered to show that every instrument is suitable for the sample being studied?

·         Are the size and kind of reliability coefficients included while discussing reliability?

·         If the tool was specially developed for the study so does the researcher explain the steps involved in the development and validation of an instrument?

·         Are the methods for administering, scoring, tabulating, and interpreting an instrument that was created especially for the study well explained?

Validity and Reliability

The researcher is required to include the validity and reliability of the included instruments therefore, the critic needs to assess if this information is added or not.

Data Analysis

Data analysis is thought to be a difficult procedure. The goal of the research is to determine which statistical test should be run, why it should be run, and how to interpret the results. Descriptive statistics are generally used in descriptive research, whereas inferential statistics are used in correlational, quasi-experimental, and experimental studies. In qualitative research, other methods are used for data analysis. The task for the critic here is to identify which analysis method is used and if it is appropriate for the current data or study.

Study Finding

The discussion of findings should be logical, related to the literature review, and supported by the hypothesis. It should also consider the study's strengths and weaknesses, and whether the findings are generalizable. Moreover, the researcher should assess the design, sampling, and analysis of the study and suggest future research in the specific area. The critic also determines if all the findings are explained well following the hypotheses.

Conclusion and Recommendation

The researcher needs to include a thorough conclusion and recommendations for future research. It should provide adequate detail regarding the study and create the way for future research projects. The researcher is also required to add the strengths and limitations of the study. In short, the researcher summarizes the whole research with some other important details. The critic determines if the conclusion and recommendation section includes above mentioned ingredients.

Article References

The publications should ideally have been published within the last five years, however occasionally an exception may apply if insufficient research has been done on a given subject.
The kind and source of the literature that is provided is another crucial factor to take into account. The reference's length should be sufficient and all of the references should be pertinent to the topic at hand. Moreover, the references should be arranged in alphabetical order following APA standards.

Conclusion

From the above discussion, it can be noted that doing critical analysis is not an easy process; however, it becomes less difficult if we are aware of the standards with which we need to compare the study. In critical analysis, we not only focus on the limitations of the study but we identify which element is included in the study and which factors are ignored, i.e. we need to emphasize both strengths and weaknesses. Moreover, critical analysis helps to improve the quality of the study.
