# Quantitative Research Paper Critique Samples

**Critique of a Research Article**

The goal of this activity is to give you an opportunity to apply whatever you learned in this course in evaluating a research paper. Warning!!!!You might have done some article summaries or even critical evaluation of some resources. However, this activity is unique because you evaluate a research article from a methodology perspective.

For this assignment you briefly summarize and extensively evaluate the attached educational research article (If you cannot download the article please go to BeachBoard/Content/Articles to download the article).

This assignment should be done individually. In the summary section, you should write a brief (up to 500 words) summary of the article in your own words. Don’t use copy and paste try to rephrase. This will be a good practice for your final project’s literature review. In the critique section, you evaluate the article using the following grading criteria.

**Grading criteria for research critique**

In your summary, you should identify main elements of the research including

1. Research problem

2. Research goal

3. Hypothesis

4. Research Questions

5. Research Method (briefly explain)

6. Sample (participants)

7. Variables

8. Tools (instruments, tests, surveys)

9. Main findings (brief summary of the results)

10. Conclusion

The critique part should be 2-3 pages (1000-2000 words) and include to the following sections. Your critique should be longer than your summary and you pay special attention to the **design and procedure**. Your grade on this assignment is based on your answer the following questions.

There is a long list of questions. You don’t have to address all questions. However, you should address highlighted questions. Some questions are relevant to this article some are not. I listed so many questions simply because I’d like you to learn what to look for in evaluating a research article.

The format of your paper should NOT be like a Q & A list. Instead, you should integrate your answers into an essay format similar to the given examples.

5. Does the review conclude with a brief summary of the literature and its implications for the problem investigated?

6. Do the implications discussed form an empirical or theoretical rationale for the hypotheses which follow?

Hypotheses

**Method**

*Subjects*

2. If a sample was selected, is the method of selecting the sample clearly described?

3. Is the method of sample selection described one that is likely to result in a representative, unbiased sample?

*4. *Did the researcher avoid the use of volunteers?

5. Are the size and major characteristics of the sample described?

*6. *Does the sample size meet the suggested guideline for minimum sample size appropriate for the method of research represented?* *

Instruments

1. Is the rationale given for the selection of the instruments (or measurements) used?

2. Is each instrument described in terms of purpose and content?

3. Are the instruments appropriate for measuring the intended variables?

4. Is evidence presented that indicates that each instrument is appropriate for the sample under study?

5. Is instrument validity discussed and coefficients given if appropriate?

6. Is reliability discussed in terms of type and size of reliability coefficients?

7. If appropriate, are subtest reliabilities given?

8. If an instrument was developed specifically for the study, are the procedures involved in its development and validation described?

9. If an instrument was developed specifically for the study, are administration, scoring or tabulating, and interpretation procedures fully described?

Design and Procedure

1. Is the design appropriate for answering the questions or testing the hypotheses of thestudy?

*2. *Are the procedures described in sufficient detail to permit them to be replicated by another researcher?

3. If a pilot study was conducted, are its execution and results described as well as its impact on the subsequent study?

4. Are the control procedures described?

5. Did the researcher discuss or account for any potentially confounding variables that he or she was unable to control for?

**Results**

1. Are appropriate descriptive or inferential statistics presented?

2. Was the probability level, α, at which the results of the tests of significance were evaluated,

specified in advance of the data analyses?

3. If parametric tests were used, is there evidence that the researcher avoided violating the

required assumptions for parametric tests?

4. Are the tests of significance described appropriate, given the hypotheses and design of the

study?

5. Was every hypothesis tested?

6. Are the tests of significance interpreted using the appropriate degrees of freedom?

7. Are the results clearly presented?

8. Are the tables and figures (if any) well organized and easy to understand?

9. Are the data in each table and figure described in the text?

**Discussion (Conclusions and Recommendation)**

1. Is each result discussed in terms of the original hypothesis to which it relates?

2. Is each result discussed in terms of its agreement or disagreement with previous results

obtained by other researchers in other studies?

3. Are generalizations consistent with the results?

4. Are the possible effects of uncontrolled variables on the results discussed?

5. Are theoretical and practical implications of the findings discussed?

6. Are recommendations for future action made?

7. Are the suggestions for future action based on practical significance or on statistical

significance only, i.e., has the author avoided confusing practical and statistical

significance?

8. Are recommendations for future research made?

**Make sure that you cover the following questions in your critique even if you have already covered them in your crtique. **

1. Is the research important? Why?

2. In your own words what methods and procedures were used? Evaluate the methods and procedures.

3. Evaluate the sampling method and the sample used in this study.

4. Describe the reliability and validity of all the instruments used.

5. What type of research is this? Explain.

6. How was the data analyzed?

QUANTITATIVE CRITIQUE 3Quantitative Article CritiqueThis paper is a review of the article titled

Accuracy of Non-contact Infrared ThermometryVersus Rectal Thermometry in Young Children Evaluated in the Emergency Department for Fever.

The article describes a research study performed to determine the accuracy of infraredthermometry which is a device that uses ³blackbody radiation emitted from a warm surface and provides an estimate of that surface¶s temperature´ (Fortuna et al, 2009).The thermometer utilized in the study is a handheld thermometer that is touched to theforehead and then gives a reading. Rectal temperatures have been the standard for takingtemperatures in children, but this is a much more invasive and time consuming procedure thaninfrared thermometry (Fortuna et al., 2009).Temperatures of each participant were taken using both the rectal thermometry methodand the infrared thermometry method (Fortuna et al., 2009). These temperatures were thencompared to determine the accuracy of the infrared thermometry (Fortuna et al., 2009). Theresults of the study showed that the infrared thermometer was not accurate when compared totemperatures that were measured with a rectal thermometer (Fortuna et al., 2009).

Purpose and Problem Statement

The problem being discussed in the article is clearly stated. There are a few instanceswhere a description of the study is provided such as, ³We evaluated the accuracy of a non-contact infrared thermometer compared with a rectal thermometer´, and ³We specifically soughtto determine the agreement between the measurements taken by this device and standard rectalthermometry´ (Fortuna et al., 2009). The article contains information about the population(young children in the Emergency Department) and contains the variables (rectal thermometry
