Examples. 5 0 obj Experimental and quasi-experimental designs for research. One technique is to relate the variables, the researchquestions or hypotheses, and sample items on the survey instrument so that a reader can easilydetermine how the data collection connects to the variables and questions/hypotheses. With pre-experimental designs, the researcher studies a single group and provides anintervention during the experiment. Design a plan for procedures for an experimental study. Plan to includea table and a discussion that cross-reference the variables, the questions or hypotheses, and specificsurvey items. Consider the following suggestions when writing the method section for anexperiment: Describe the selection process for participants as either random or nonrandom (e.g., convenientlyselected). population in this study was all song lyrics of Katy Perry. i. Have participants take photographs or videotapes (i.e., photo elicitation), and then interview them about the materials. Figure 9.1 Data Analysis in Qualitative ResearchStep 1. Another example of a within-group design would be a study of thebehavior of a single individual over time in which the experimenter provides and withholds atreatment at different times in the experiment to determine its impact. With total population sampling a researcher chooses to examine the entire population that has one or more shared characteristics.

Examine website main pages. These unusualforms create reader interest in a proposal and can capture useful information that observations andinterviews may miss. Thetraditional approach in the social sciences is to allow the codes to emerge during the data analysis. Other procedures to place control into experiments involve usingcovariates (e.g., pretest scores) as moderating variables and controlling for their effects statistically,selecting homogeneous samples, or blocking the participants into subgroups or categories andanalyzing the impact of each subgroup on the outcome (Creswell, 2012). Xs and Os in a given row are applied to the same specific persons. The researcher builds a complex, holistic picture, analyzes words, reports detailed views of informants, and conducts the study in a natural . Guiding Question.

Natural setting: Qualitative researchers tend to collect data in the field at the site where participants experience the issue or problem under study. The explicitstatement of values condition was created by adding to each of the three counseling conditions a 2-min leader that portrayed the counselor describing to the client her counseling approach and associated values including for the two feminist conditions a description of her feminist philosophical orientation, liberal or radical.

General, Target, and Accessible Population: Demystifying the Concepts for Effective Sampling endobj See Borg & Gall,2006). Threats to construct validityoccur when investigators use inadequate definitions and measures of variables.Table 8.6 Types of Threats to External ValidityTypes of Description of Threat In Response, Actions the Researcher Can TakeThreats toExte rnal The researcher restricts claims about groups to which theValidity results cannot be generalized. Indicate the type or types of data to be collected. . As with the section on surveys, the intent here is to highlight key topics to be addressed in anexperimental methods section of a proposal. Mark Lipsey has authored a major book on the topics of experimental designs and statistical powerof those designs. What will the gatekeeper gain from the study? There are those involving participants (i.e., history, maturation, regression,selection, and mortality), those related to the use of an experimental treatment that the researchermanipulates (i.e., diffusion, compensatory and resentful demoralization, and compensatory rivalry),and those involving procedures used in the experiment (i.e., testing and instruments).Table 8.5 Types of Threats to Internal ValidityType of Threat to Description of Threat In Response, Actions the Researcher Can TakeInternal ValidityHistory Because time passes during an experiment, events The researcher can have both the experimental and can occur that unduly influence the outcome beyond control groups experience the same external events. Thisoften leads to compromises in the researchers ability to disclose information and raises issues of animbalance of power between the inquirers and the participants.

They present many examples of different types of designs, such as reversal designsand multiple-baseline designs, and they enumerate the statistical procedures that might be involved inanalyzing the single-subject data. 176). In many experiments, those of a type calledbetween-subject designs, the investigator compares two or more groups (Keppel & Wickens, 2003;Rosenthal & Rosnow, 1991). Advance how the description and themes will be represented in the qualitative narrative.The most popular approach is to use a narrative passage to convey the findings of the analysis. When onegroup receives a treatment and the other group does not, the experimenter can isolate whether it is thetreatment and not other factors that influence the outcome.COMPONENTS OF A SURVEY METHOD PLANThe design of a survey method section follows a standard format. Step 1. significance and concern to the study. Provide a reference to this purpose from one of the survey method texts (several areidentified in this chapter). Use the coding process to generate a description of the setting or people as well ascategories or themes for analysis. Conduct a focus group interview, audiotape the interview, and transcribe it. Inthe health sciences, a popular approach is to use predetermined codes based on the theory beingexamined. Tell the reader about the number of participants in each group and the systematic procedures fordetermining the size of each group. The descriptive research method primarily focuses on describing the nature of a demographic segment, without focusing on "why" a particular phenomenon occurs. If a random assignment is made, discuss how the project will randomly assignindividuals to the treatment groups. Throughoutthe book, he brings in practical examples to illustrate his points.CHAPTER NINEQualitative MethodsQualitative methods demonstrate a different approach to scholarly inquiry than methods of quantitative research. Researchers can select participants by random selection or random sampling. students of 10 th class of particular school is an example of existent type of population and the population of heads and tails obtained by tossing a coin on infinite number of times is an example of hypothetical population. Alternatively, the criteria for matching might be ability levelsor demographic variables. O represents an observation or measurement recorded on an instrument. endobj [Authors discussed the instrument. Decide whether audience members areknowledgeable enough about the characteristics of qualitative research that this section is notnecessary. In qualitative research, theimpact of this process is to aggregate data into a small number of themes, something like five to seventhemes (Creswell, 2013). Suggest why or why not theresults were significant, drawing on past literature that you reviewed (Chapter 2), the theory used inthe study (Chapter 3), or persuasive logic that might explain the results. A discussion about participants and site might include fouraspects identified by Miles and Huberman (1994): (a) the setting (i.e., where the research will takeplace), (b) the actors (i.e., who will be observed or interviewed), (c) the events (i.e., what the actorswill be observed or interviewed doing), and (d) the process (i.e., the evolving nature of eventsundertaken by the actors within the setting). <>70 0 R]/P 32 0 R/S/Link>> Occasionally, tests of statistical significance, such as t tests, are used tocompare the pooled mean of the baseline and the treatment phases, although such procedures mayviolate the assumption of independent measures (Borg & Gall, 2006). 2. Writing Exercises 1. Using Fowlers (2009) table, forexample, with a margin of error of +/4%, a confidence error of 95%, and a 50/50 chance that thesample contains our characteristic, we arrive at a sample size of 500.Instrumentation As part of rigorous data collection, the proposal developer also provides detailed informationabout the actual survey instrument to be used in the proposed study. As a research tip, I urge researchers to look at qualitative dataanalysis as following steps from the specific to the general and as involving multiple levels ofanalysis. The questioning approach is alsoused in transformative approaches to qualitative research. Attach, as an appendix, the approval letter from the IRBand discuss the process involved in securing permissions. Asking, What were the lessons learned? captures the essence of this idea(Lincoln & Guba, 1985). However, due to the large sizes of populations, researchers often cannot test every individual in the population because it is too expensive and time . Many qualitative researchers also usevisuals, figures, or tables as adjuncts to the discussions. Guest and colleagues (2012)discussed and illustrated the use of codebooks in qualitative research. In Table 8.3, I show how the factors, in combination, lead to the selection of a number ofcommon statistical tests. We did not anticipate the code retriggering to emerge in our study, and it surfaced from the perspective of a psychologist called into the campus to assess the response. Organize and prepare the data for analysis. A related topic would be the number of sites and participants to be involved in your study. Steps for addressingthese potential issues are also presented in Table 8.6. The statistical significance testing reports anassessment as to whether the observed scores reflect a pattern other than chance. The X number is based on a fraction determined by the number of peopleon a list and the number that are to be selected on the list (e.g., 1 out of every 80th person). They can also decide how they want to collect the data, online, offline, or via phone. Start coding all of the data.

Report information about the number of members of the sample who did and did not returnthe survey. Another approach is equally viable. The book Research Design: Qualitative, Quantitative and Mixed Methods Approaches by Creswell (2014) covers three approaches-qualitative, quantitative and mixed methods. Floyd Fowler provides a useful text about the decisions that go into the design of a survey researchproject. (pp. One needs to first determine the subgroups to beanalyzed in study. Discuss plans for pilot testing or field-testing the survey and provide a rationale for these plans.This testing is important to establish the content validity of scores on an instrument and to improvequestions, format, and scales. 380-381). 5. Indicate the number of people in the sample and the procedures used to compute this number. Creswell et al. This purpose is to generalize from a sample to apopulation so that inferences can be made about some characteristic, attitude, or behavior of thispopulation. Look for ways of reducing your total list of categories by grouping topics that relate to each other. (1995). Alternatively, a systematic sample can have precision equivalent random sampling(Fowler, 2009). In an experiment, investigators may also identify a sample andgeneralize to a population; however, the basic intent of an experimental design is to test the impactof a treatment (or an intervention) on an outcome, controlling for all other factors that might influencethat outcome. David. participants from the study population in an unbiased manner, the standardized questionnaire or intervention they receive, and statistical methods used to . This inductive process illustrates working back and forth between the themes and the database until the researchers have established a comprehensive set of themes. In addition, an insignificant number of ]Concurrent and convergent validity (Campbell & Fiske, 1959) of these measures wasestablished through factor analysis, and was found to be at an adequate level. (Several of these tests are mentioned in Table 8.3,which was presented earlier.) Third edition. Have a participant keep a journal or diary during the research study.

Codes that are unusual, and that are, in and of themselves, of conceptual interest to readers. Of the students,95% were between the ages of 18 and 21. In this case, the researchers might develop a qualitative codebook, a table that contains alist of predetermined codes that researchers use for coding the data. 386 0 obj This willrequire drawing inferences and conclusions from the results. 8.

The researcher also should report on the materials used for theexperimental treatment (e.g., the special program or specific activities given to the experimentalgroup). Ethnographerscan end a study, Wolcott (1994) said, by stating further questions.

Step 6. The key idea behind qualitative research is to learn about theproblem or issue from participants and to address the research to obtain that information.Reflexivity: In qualitative research, the inquirer reflects about how their role in the study andtheir personal background, culture, and experiences hold potential for shaping theirinterpretations, such as the themes they advance and the meaning they ascribe to the data. Include sample items from the instrument so that readers can see the actual items used. Indicate the number of people who will test the instrument and the plansto incorporate their comments into final instrument revisions.

Englewood Cliffs, NJ: Prentice Hall. Data Analysis Tell the reader about the types of statistical analysis that will be used during the experiment.

For example,researchers match participants in terms of a certain trait or characteristic and then assign oneindividual from each matched set to each group. Step 4. The Publication Manual ofthe American Psychological Association (American Psychological Association [APA], 2010)suggests that the most complete meaning of the results come from reporting extensive description,statistical significance testing, confidence intervals, and effect sizes. Using an Internet survey and administering it online has been discussed extensively inthe literature (Nesbary, 2000; Sue & Ritter, 2012). The calculation of effect size varies for different statistical tests:it can be used to explain the variance between two or more variables or the differences among meansfor groups. Step 4. You can publish your book online for free in a few minutes. For visual materials, some form of system is needed to organize the materials so that they can be easily retrieved. These tables require three elements. Reliability of thefactors was established through the coefficient alpha. First of all, there is no specific answer to this question; although I have taken the position(Creswell, 2013) that sample size depends on the qualitative design being used (e.g., ethnography,case study). With randomization, a representative sample from a population provides theability to generalize to a population. Three counseling scripts were initially developed on the basis of distinctions between nonsexist-humanistic, liberal, and radical feminist philosophies and attendant counseling implications. This means reporting efforts by authors to establish validity in quantitativeresearchwhether one can draw meaningful and useful inferences from scores on the instruments.The three traditional forms of validity to look for are (a) content validity (do the items measure thecontent they were intended to measure? In this study, descriptive research is applied as the design.

For example, when studying a sensitive topic, it isnecessary to mask names of people, places, and activities. Here the author underlines that "the types of data one would collect and analyze would differ considerably." . Provide a diagram or a figure to illustrate the specific research design to be used. The dependentvariable is the response or the criterion variable presumed to be caused by or influenced by theindependent treatment conditions and any other independent variables. Then the researchers review all of the data, make sense of it, and organize it into categories or themes that cut across all of the data sources. The total population of the tenth grade students in Office Management major is 107 students from three classes. Creswell (2013) notes that qualitative research methods typically aid in researching topics where little is known about a phenomenon. A final step in the data analysis is to present the results in tables or figures and interpret theresults from the statistical test. The results can be downloaded into aspreadsheet or a database for further analysis. Daniel. Backyard research (Glesne & Peshkin,1992) involves studying researchers own organization, or friends, or immediate work setting. Step 3. If studying the backyard is essential, then researchers hold theresponsibility for showing how the data will not be compromised and how such information will notplace the participants (or the researchers) at risk. <>3]/P 6 0 R/Pg 389 0 R/S/Link>> When the sample input or data is obtained, and the sample mean x is calculated, the sample mean obtained is different from the population mean . <> Insome survey projects, the researcher assembles an instrument from components of severalinstruments. In many qualitative articles, researchers also discuss the literature atthe end of the study (see the discussion in Chapter 2). The STANDS4 Network . McMillian and Schumaker (2010) use the term sampling frame to describe a smaller subset of the general population for a study. Consider the following: Name the survey instrument used to collect data. endobj and test-retest correlations (Are scores stable over time when the instrument isadministered a second time?). They may use a protocolan instrument for collecting databut the researchers are the ones who actually gather the information. This up-close information gathered by actually talking directly to people and seeing them behave and act within their context is a major characteristic of qualitative research. Step 2. Susan Neuman and Sandra McCormick have edited a useful, practical guide to the design of single-subject research. This procedure eliminates the possibility of systematic differences among characteristicsof the participants that could affect the outcomes so that any differences in outcomes can be attributedto the experimental treatment (Keppel & Wickens, 2003). The basic idea behind these programs is that using the computer is an efficient means forstoring and locating qualitative data. The number of the selected population will be number of students ranging on 17-18 years old. Gibbs et al (20 07) and Patton (2002) demonstrated that there were a number of methods the research ers would . This requires that characteristics of the population members be known so that the populationcan be stratified first before selecting the sample (Fowler, 2009). According to Creswell (2014), phenomenology research typically ranges from three to ten participants (p. 189). (d)______ Collapse items into scales? These factors, in combination, enable aresearcher to determine what statistical test will be suited for answering the research question orhypothesis. Try this preliminary organizing scheme to see if new categories and codes emerge. Description. Identify whether the sampling design for this population is single stage or multistage (calledclustering). Then, he suggested going to a table found in many survey books (see Fowler, 2009)to look up the appropriate sample size. This analysis should indicate the means, standard deviations, and range ofscores for these variables. If there is some question about their knowledge, present the basic characteristics of qualitativeresearch in the proposal and possibly discuss a recent qualitative research journal article (or study)to use as an example to illustrate the characteristics. This is certainlyone approach to the sample size issue. A standardnotation system needs to be used in this figure.
