A helpful conceptualization to advance in the methods section is that qualitative data analysiswill proceed on two levels: (a) the first is the more general procedure in analyzing the data (seebelow), and (b) the second would be the analysis steps embedded within specific qualitative designs.For example, narrative research employs restorying the participants stories using structural devices,such as plot, setting, activities, climax, and denouement (Clandinin & Connelly, 2000).Phenomenological research uses the analysis of significant statements, the generation of meaningunits, and the development of what Moustakas (1994) called an essence description. It is broader than the concept sample frame. Also determine whether there was consistency in test administrationand scoring (Were errors caused by carelessness in administration or scoring? <> Nestor Asiamah, Henry Kofi Mensah, and Eric Fosu Oteng-Abayie For example,researchers match participants in terms of a certain trait or characteristic and then assign oneindividual from each matched set to each group. For further types of statistical tests, readers are referred to statistics methodsbooks, such as Gravetter and Wallnau (2009).Step 6. 2. In Table 8.3, I show how the factors, in combination, lead to the selection of a number ofcommon statistical tests. Alternatively, the criteria for matching might be ability levelsor demographic variables. Multiple methods of data collection. Many qualitative researchers also usevisuals, figures, or tables as adjuncts to the discussions. Researchersoften engage in multiple observations during the course of a qualitative study and use anobservational protocol for recording information while observing. endobj Pretests and treatments are varied for the four groups. Experimental researchersneed to identify potential threats to the internal validity of their experiments and design them so thatthese threats will not likely arise or are minimized. Backyard research (Glesne & Peshkin,1992) involves studying researchers own organization, or friends, or immediate work setting. With this defined, we examine the population subsets and what characterizes them. Researchers record information from interviews by making handwrittennotes, by audiotaping, or by videotaping. Survey research provides a quantitative or numeric description of trends, attitudes, or opinions of a population by studying a sample of that population. I selected these five because they were popular across the socialand health sciences today. (b)______ Check for response bias? . In wave analysis, the researcher examines returns on select items week by week todetermine if average responses change (Leslie, 1972). [Authors discussed the instrument. [Authors identified the overall design.] Design and Experimental Manipulation This study used a 3 2 2 factorial design: Orientation of Counselor (nonsexist-humanistic, liberal feminist, or radical feminist) Statement of Values (implicit or explicit) Participants Identification with Feminism (feminist or nonfeminist). 2. Consider the following: Name the survey instrument used to collect data. Comment about sensitive ethical issues that may arise (see Chapter 3). Discuss the implications of the results for practice or for future research on the topic. Insurvey research, investigators often choose a sample size based on selecting a fraction of thepopulation (say, 10%), select the size that is unusual or typical based on past studies, or base thesample size simply on the margin of error they are willing to tolerate. Step 1: Report on samplenumber who returned and did not returncan . Newbury Park, CA: Sage. Provide a reference to this purpose from one of the survey method texts (several areidentified in this chapter). endobj For example, the experiences may cause researchers to leantoward certain themes, to actively look for evidence to support their positions, and to createfavorable or unfavorable conclusions about the sites or participants. Audiovisual Materials Examine photographs or videotapes. expectations of the control group. Researchers can generate codes for this description. Overall, thisbook is for the mid-level to advanced statistics student who seeks to understand the design andstatistical analysis of experiments. Creswell (2012:3) states research designs are the specific procedures involved in the research process: data collection, data analysis, and report writing. Delimitations are the exact opposite of limitations. The first mail-out is a short advance-notice letterto all members of the sample, and the second mail-out is the actual mail survey, distributed about 1week after the advance-notice letter. These themes are the ones that appear as majorfindings in qualitative studies and are often used as headings in the findings sections (or in thefindings section of a dissertation or thesis) of studies. (e)______ Check for reliability of scales? mixed methods research (Creswell, 2008; Cohen et al., 2007; Gliner et al., 2009; Kothari, 2010). Practical research tips for proposal writers to address validity issues are as follows: Identify the potential threats to validity that may arise in your study. For single-subject research designs, use line graphs for baseline and treatment observations forabscissa (horizontal axis) units of time and the ordinate (vertical axis) target behavior. Asking, What were the lessons learned? captures the essence of this idea(Lincoln & Guba, 1985). Baseline A Treatment B Baseline A OOOOOXXXXXOOOOOOThreats to Validity There are several threats to validity that will raise questions about an experimenters ability toconclude that the intervention affects an outcome and not some other factor. Specify the form of data collection. Table 8.2 illustrates such a table using hypothetical data.Table 8.2 Variables, Research Questions, and Items on a SurveyVariable Name Research Question Item on SurveyIndependent Variable 1: Prior Descriptive research Question 1: How See Questions 11, 12, 13, 14, and 15: publication countspublications many publications did the faculty member for journal articles, books, conference papers, book produce prior to receipt of the doctorate? Qualitative observers may also engage in roles varying from a nonparticipant to a complete participant. 2021-03-30T12:20:34-07:00 In addition, gainingentry to a research site and the ethical issues that might arise are also elements of the researchersrole. (2018) Research Design: Qualitative, Quantitative, and Mixed Methods Approaches. Go through it, asking yourself, What is this about? Do not think about the substance of the information but its underlying meaning. The questioning approach is alsoused in transformative approaches to qualitative research. It is also helpful to comment on the reliability and value of the data sources. population, in human biology, the whole number of inhabitants occupying an area (such as a country or the world) and continually being modified by increases (births and immigrations) and losses (deaths and emigrations). The fourth mail-out, sent to allnonrespondents, consists of a personalized cover letter with a handwritten signature, thequestionnaire, and a pread-dressed return envelope with postage. Use the coding process to generate a description of the setting or people as well ascategories or themes for analysis. It is for the benefit of the population that researches are done. In this article, we begin with the fundamental building block of any population: the unit of analysis. These are just a few features of the software programs thatmake them a logical choice for qualitative data analysis over hand coding. Will it be measured before and after the experiment?_____________ What is the treatment condition(s)? Philosophical assumptions to consider: Ontological - what is the nature of reality (Reality is multiplex) Epistemological - what is the nature and definition of knowledge? Regardless of the form of data collection, providea rationale for the procedure, using arguments based on its strengths and weaknesses, costs, dataavailability, and convenience.The Population and Sample In the methods section, follow the type of design with characteristics of the population and thesampling procedure. Does it have established validity and reliability? 66 0 obj This means thatthe initial plan for research cannot be tightly prescribed, and some or all phases of the processmay change or shift after the researcher enters the field and begins to collect data. Identify the dependent variable or variables (i.e., the outcomes) in the experiment. Xs and Os in a given row are applied to the same specific persons. A table with numbers and percentages describing respondents and nonrespondents is auseful tool to present this information. They present a process model (as ingrounded theory), advance a drawing of the specific research site (as in ethnography), or conveydescriptive information about each participant in a table (as in case studies and ethnographies). How to pronounce Creswell? Thetraditional approach in the social sciences is to allow the codes to emerge during the data analysis. This purpose is to generalize from a sample to apopulation so that inferences can be made about some characteristic, attitude, or behavior of thispopulation. If audiotaping is used, researchers need to planin advance for the transcription of the tape. The researcher sets a rejection level of no effect, such asp = 0.001, and then assesses whether the test statistic falls into this level of rejection. 60 0 obj The benefits of an experiment may be unequal or The researcher can provide benefits to both groups,Compensatory/Resentful resented when only the experimental group receives such as giving the control group the treatment after thedemoralization the treatment (e.g., experimental group receives experiment ends or giving the control group some therapy and the control group receives nothing). When data on a pretest or posttest show marked deviation from a normal distribution, usenonparametric statistical tests. Conduct chart audits. Design and analysis: A researchers handbook (4th ed.). With total population sampling a researcher chooses to examine the entire population that has one or more shared characteristics. What specific steps will be taken in data analysis to do the following:(a)______ Analyze returns? . With randomization, a representative sample from a population provides theability to generalize to a population. In this situation, the process for maskinginformation requires discussion in the proposal.Data Collection Procedures Comments about the role of the researcher set the stage for discussion of issues involved incollecting data. They may use a protocolan instrument for collecting databut the researchers are the ones who actually gather the information. 3.2.1 Quantitative Research Methodology Creswell (2013) defines quantitative research as: "A means of testing objective theories by examining the relationship among variables. This includes limiting the number of results, excluding resources and only using specific research procedures to gather data to reach a particular objective. 3.2. The key characteristics of survey research stated by Creswell (2012) are "sampling from a population, collecting data through questionnaires and interviews, designing instruments for data collection, and obtaining a high response rate" (pp. Sampling is a way that you can choose a smaller group of your population to research and then generalize the results of this across the larger population. 1990 by the APA. Still other independent variables can be statistically controlled, suchas demographics (e.g., gender or age). 5 0 obj Sample Arifin (2012:215) defines sample is the part of population to be Multiple sources of data: Qualitative researchers typically gather multiple forms of data, such as interviews, observations, documents, and audiovisual information rather than rely on a single data source. posttest, thus impacting the scores on the outcome. Indicate steps taken to obtain permission from the institutional review board (IRB) (see Chapter4) to protect the rights of human participants. This kind of purposive sampling technique is commonly used to generate reviews of events or experiences, which is to say, it is common to studies of particular groups within larger . Report information about the number of members of the sample who did and did not returnthe survey. 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). For visual materials, some form of system is needed to organize the materials so that they can be easily retrieved. (2006). Form these topics into columns, perhaps arrayed as major, unique, and leftover topics. <>39]/P 24 0 R/Pg 389 0 R/S/Link>> 61 0 obj 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). This method is used for sampling data from respondents that are representative of a population and uses a closed ended instrument or open-ended items. Step 4. US English. In N. L. Gage (Ed.

o Chapter 1 opens with-definition of research approaches and the author gives his opinion that selection of a research approach is based on the nature of the research problem . 385 0 obj He addresses use of alternative sampling procedures, ways of reducing nonresponse rates,data collection, design of good questions, employing sound interviewing techniques, preparation ofsurveys for analysis, and ethical issues in survey designs.Keppel, G. & Wickens, T. D. (2003). In many qualitative articles, researchers also discuss the literature atthe end of the study (see the discussion in Chapter 2). 6. Table 9.2 Qualitative Data Collection Types, Options, Advantages, and LimitationsNOTE: This table includes material adapted from Bogdan & Biklen (1992), Creswell (2013), and Merriam (1998). A confidence interval is a range of values (an interval) thatdescribes a level of uncertainty around an estimated observed score. 384 0 obj telerik asp net core grid selected row. Creswell, J.W. However, at the same time if the sample is too large data . Sage, Los Angeles. The method section must list and clearly identify all theindependent variables in an experiment. Creswell et al.

Where, SS = Sample Size. endobj Creswell, Fetters and Ivankova (2004:7) argue that mixed methods research is more than . The baseline behavioris assessed, the treatment provided, and then the treatment is withdrawn. Another approach is equally viable. Focus should also be on whether or not the researchquestions/hypotheses were supported.Example 8.1 A Survey Method SectionAn example follows of a survey method section that illustrates many of the steps just mentioned.This excerpt (used with permission) comes from a journal article reporting a study of factorsaffecting student attrition in one small liberal arts college (Bean & Creswell, 1980, pp. endobj Table 8.5 displays these threats,provides a description of each one of them, and suggests potential responses by the researcher so thatthe threat may not occur. The researcher took students of grade eleven as the population in this study, Researchers send this fourth mail-out 3 weeks after the second mail-out. endobj Areader should be able to understand the design being used, the observations, the treatment, and thetimeline of activities. Discuss a step-by-step approach for the procedure in the experiment. Finally,less desirable is a nonprobability sample (or convenience sample), in which respondents are chosenbased on their convenience and availability. Descriptive research definition: Descriptive research is defined as a research method that describes the characteristics of the population or phenomenon studied. Washington DC: Sage. 3 0 obj Step 3. In this study, the target population was the students at the tenth grade of SMA Islam Batu who were divided into two classes namely X 1 and X 2 class. [Authors discussed the instruments and the reliability of the scales for the dependent variable in the study.] Creswell (2003) portrays methodology as a coherent group of methods that harmonize one another and that have the capability to fit to deliver data and findings that will reflect the research question and suits the researcher's purpose. In other words, the purpose tells the reader what the goal of the study is, and what your study will accomplish, through which theoretical lens. When individuals can be randomly assigned to groups, the procedure is called a trueexperiment. <>70 0 R]/P 32 0 R/S/Link>> Of scales or themes for analysis hand coding to do the following: ( a ) ______ Check reliability.
