the quantitative research method is used to depict or derive more information. trial relationships. examine cause and consequence relationships. and uses numeral informations to “answer” jobs. The followers is a basic lineation of what is included in nursing research survey. and what you should review a survey for: 1.

Aima. Normally found in debut or job statement.B.

Might be stated as a chief research inquiry or hypothesis for the survey. c. Main focal point may non be clearly labeled necessitating reader to synthesise the intent from this subdivision.

2. Samplea. Expression for representativeness of sample.1. Representativeness-Subjects are indiscriminately selected from the mark population.

2. Target population-Population from which the sample is chosen and study findings are generalized to. Examples: All adult females ages 65 to 90 with a diagnosing of acute MI. 3. Sample size-The sample size should be every bit big as possible.

Sampling mistake decreases as sample size additions ( general regulation ) . B. Random Vs. non-random sample

1. Convenience. purely voluntary trying choice ( normally non-random ) may hold bias in representativeness. 2.

Bias in trying choice agencies those chosen to take part may differ from those non chosen. A randomised sample reduces bias in trying choice. Note: Many nursing primary mentions are based on non-random convenience samples! Bias may be reduced through certain informations analysis techniques. and addressed in design limittions. 3. Methodsa. Data aggregation – Procedure should be clearly defined ( based upon job and sample ) . 1.

Description of informations aggregation clip frames. where information collected. participant’s permission process. and confidentiality/anonymity confidence. 2. How questionnaires.

graduated tables and/or interviews were utilized in the survey. Note: Method of informations aggregation can besides hold prejudice. Use of interview technique to garner information has the least prejudice because the research worker has less influence on the participant’s replies. B.

Study Designs1. Permits the scrutiny of the study’s research variables. Variables are qualities. or features of individuals. things. or state of affairss under survey. 2. Descriptive-Gain more information about features of a group.

Example: pilot or exploratory. 3. Correlational-Examines relationships between variables in a group. 4. Quasi-experimental/ Experimental-Examines causality. explains relationships. utilizations control and experimental groups.

Note: Experimental designs are the most scientific!c. Measurements/Instruments1. Description of the informations aggregation instruments. graduated tables. questionnaires. Example: # inquiries.

hiting scope. etc. 2. Inclusion of dependability and cogency of instruments.a. Reliability-Measurement of how systematically similar consequences are obtained every clip the scale/instrument is used. b. Validity-Measurement of how accurately the instrument reflects some of the variables in the survey ( features under survey ) .

3. Dependability and cogency are of import because the study’s consequences should ne’er be influenced by instrument/scale mistake. 4. Datas Analysis:

a. Summarizes and describes the information in a logical.

apprehensible format from research variables capable of being quantified ( converted to Numberss ) . 1. Descriptive statistics-Clearly and intelligibly describes the sample largely utilizing frequence distribution. mean. average. manner. scope. % and others.

2. Inferential statistics-Tests the research inquiries or hypothesis utilizing T-Tests. ANOVA. multiple arrested developments. etc.

When the research program hypothesizes relationships between variables. it is necessary to clear up expected variable relationships utilizing independent and dependent variables. a. Dependent variable-Response.

behaviour. or outcome the research worker wants to explicate. B. Independent variable-The intervention or experimental variable manipulated by the research worker to make an consequence on the dependant variable. Note: One easy manner of distinguishing between these variables is to retrieve that independent means standing entirely. and dependent agencies trusting on something. Don’t let statistics frighten you! If you are a novitiate at article review. work on being able to happen the sample adequately represented in an included tabular array.

chart or graph. Take little stairss! 5. Findings/Nursing Implications/ Decisions:a. The findings and decisions should be relevant.

functional. and generated from the survey. B.

Fishy prejudice if questionable generalizability. sample defect. or weak design. Note: Don’t expect flawlessness! Every study might offer something utile. thoughts you can utilize. better.

or develop! “POLISHING” THE CRITIQUERemember that all research is capable to a review. But until you. the reader have critiqued the study. you have no manner of cognizing if the survey is based on good. systematic research rules. Follow the above lineation following clip you read a nursing research article. Jot down the outline headers ( intent. sample.

methods. informations analysis. and nursing deductions ) . And happen the content from the article you chose to read. For the first twosome of surveies. critique the article backwards and forwards.

This is clip good spent because you will hold an sentiment on the value of the nursing survey by the terminal of the study. Now let’s see how nonsubjective that sentiment is! Brink and Wood ( 1994 ) include a simple appraisal to help you in finding the adequateness of the nursing research you have read. The more equal the survey. the more you can larn from the research conducted! After you have thoroughly read your chosen article. use “test the study” ( Brink & A ; Wood.

1994: “Test the Study” involves giving the article a survey evaluation: A. Defective study-Lack lucidity significance.B. Substandard study-Lacks completeness.C. Adequate Study-Covers basic research aims.

Follow these simple stairss:1. Get out paper and pencil.2.

List each of the major portions-problems/purpose. sample. methods.analysis. findings and decisions. 3.

Across the top of the paper list classs: defective. substandard and adequate. 4. Check off which heading each subdivision of the article falls. 5.

Add up cheques in faulty column and multiply x1.

6. Add up cheques in deficient column and multiply x2.

7. Add up cheques in equal column and multiply x3.8. Entire tonss:& gt ; 12 points-Adequate survey.8-11 points-Substandard survey.Deductions:1. An equal statement of purpose clearly describes what the survey is approximately.

2. An equal sample is clearly related to the population being examined and has representative cape. 3.

An equal study on methods will state you what. why and how the survey was done in sufficient item. 4. An equal analysis is comprehendible. responsive to the information. and congruent with all presented stuff. 5. An equal decision has a sense of conclusiveness and closing and is derived from the job and reflects the findings ( Brink & A ; Wood.

1994 ) . Check YOUR SCORE AGAINST THE FEELING YOU HAD AFTER YOU THOROUGHLY READ THE ARTICLE-DO THEY AGREE. OR IS THE SCORE TOTALLY INCONSISTENT WITH YOUR FEELINGS? Always utilize your nonsubjective marking until after pattern. your feelings and the tonss agree systematically! You can review nursing research articles! .

Happy reading!
