The method section must list and clearly identify all theindependent variables in an experiment. Survey research provides a quantitative or numeric description of trends, attitudes, or opinions of a population by studying a sample of that population. Indicate the inferential statistical tests used to examine the hypotheses in the study. It can also suggest new questions that need to be askedquestionsraised by the data and analysis that the inquirer had not foreseen earlier in the study. 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.

Figure 9.1 Data Analysis in Qualitative ResearchStep 1. Instruments Manipulation checks. 64 0 obj [Validity and reliability were addressed. While at the University of Nebraska-Lincoln, he held the Clifton Endowed Professor Chair, served as director of a mixed methods research office, founded the SAGE journal, the Journal of Mixed .

Dictionary of Current English (1986:720), research is defined as "systematic investigation . Three counseling scripts were initially developed on the basis of distinctions between nonsexist-humanistic, liberal, and radical feminist philosophies and attendant counseling implications. I recommend selecting a random sample, in whicheach individual in the population has an equal probability of being selected (a systematic orprobabilistic sample).

Thus, it is important to clarifythe meaning of these last three reports of the results. In specific, measurable terms, what is the population for whom you will hold yourself accountable to meet desired outcomes? If so, how?_____________ How many people will be in the sample? What isthe tone of the ideas? Step 2. One group, for example,may participate in a special computer-assisted learning plan used by a teacher in a classroom. Login . How will it be measured? In addition, gainingentry to a research site and the ethical issues that might arise are also elements of the researchersrole. In many qualitative studies, inquirers collectmultiple forms of data and spend a considerable time in the natural setting gathering information. This communication as possible during the experiment. Englewood Cliffs, NJ: Prentice Hall. Creswell (2012) states that population is Alternatively, a systematic sample can have precision equivalent random sampling(Fowler, 2009). They hypothesized that feminist participants would be more receptive to a radicalfeminist counselor than would nonfeminist participants and that nonfeminist participants would bemore receptive to a nonsexist and liberal feminist counselor. In anappendix to the proposal, attach sample items or the entire instrument. The constructs were represented by 25measuresmultiple items combined on the basis of factor analysis to make indicesand 27measures were single item indicators. 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). Occasional missing data on particular items were handled by a pairwise deletion procedure. 386 0 obj McMillian and Schumaker (2010) use the term sampling frame to describe a smaller subset of the general population for a study. Qualitative observers may also engage in roles varying from a nonparticipant to a complete participant. A research population is generally a large collection of individuals or objects that is the main focus of a scientific query. Learn more. As with any biological population, the size of a human population is limited by the supply of food, the effect of diseases, and other environmental factors. in detail with a brief explanation of population and . The most rigorous methodfor selecting the sample is to choose individuals using a random sampling, a topic discussed in manyintroductory statistics texts (e.g., Gravetter & Wallnau, 2009). Intervening variables significantly related to intent to leavewere then regressed on organizational variables, personal variables, environmental variables,and background variables. Then the researcherdraws a figure to illustrate the design, using appropriate notation. For further types of statistical tests, readers are referred to statistics methodsbooks, such as Gravetter and Wallnau (2009).Step 6. Asidefrom the small number that characterizes qualitative research, how many sites and participants shouldyou have? 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 the design of anexperiment, the researcher identifies participants in the study, the variablesthe treatment conditionsand the outcome variablesand the instruments used for pretests and posttests and the materials to beused in the treatments. 60 0 obj Steps for addressingthese potential issues are also presented in Table 8.6.

Data Analysis Tell the reader about the types of statistical analysis that will be used during the experiment. Decide whether audience members areknowledgeable enough about the characteristics of qualitative research that this section is notnecessary. The total population of the tenth grade students in Office Management major is 107 students from three classes. Hand coding is a laborious and time-consuming process, even for data from a few individuals. Consider the following: Name the survey instrument used to collect data. Qualitative research is an inquiry approach in. Dropout rates tend to be highest among freshmen and sophomores, so an attempt was made to reach as many freshmen and sophomores as possible by distribution of the questionnaire through classes. He has written numerous journal articles and 27 books on mixed methods research, research methods, and qualitative research. Report the descriptive statistics calculated for observations and measures at the pretest orposttest stage of experimental designs. regress toward the mean. Indicate whether the survey will be cross-sectionalwith the data collected at one point in timeor whether it will be longitudinalwith data collected over time. 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. Conduct an unstructured, open-ended interview; audiotape the interview; and transcribe it. 57 0 obj Writing Exercises 1. Definition. Creswell gives an overview of the commonality of the five research methods (p. 102) before explaining key differences among more similar seeming types of research, e.g. Population Administer measures of the dependent variable or a variable closely correlated with the dependent variable to the research participants. The sample size formula for the infinite population is given by: S S = Z 2 P ( 1 P) C 2. Berryman-Fink and Verderber (1985) reported internal consistency reliabilities of .86 and .89 for the original versions of these two subscales. interprets the meaning of the information. Use the coding process to generate a description of the setting or people as well ascategories or themes for analysis. 321322).Methodology The site of this study was a small (enrollment 1,000), religious, coeducational, liberal arts college in a Midwestern city with a population of 175,000 people. However, due to the large sizes of populations, researchers often cannot test every individual in the population because it is too expensive and time . According to Smith et al., (1979), quantitative research employs the traditional, the positivist, the experimental, or the empiricist method to enquire into an identified problem. Questions of access arise here,and the researcher might refer to availability of sampling framesmail or published listsofpotential respondents in the population. 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. Researchers send this fourth mail-out 3 weeks after the second mail-out. Comment about sensitive ethical issues that may arise (see Chapter 3). Information and translations of Creswell in the most comprehensive dictionary definitions resource on the web. 3 0 obj Who developed the instrument?_____________ What are the content areas addressed in the survey? For example, a factorial design experiment, a variation on the between-group design, involves using two or more treatment variables to examine the independent andsimultaneous effects of these treatment variables on an outcome (Vogt, 2011). These four topics generally are sufficient. population might tell us if we asked every member of the larger population the same questions" (1). The symbol R indicates random assignment. Assign participants to matched pairs on the basis of their scores on the measures described in Step 1. Even if an interview is taped, I recommend that researcherstake notes in the event that recording equipment fails. I recommend thefollowing research tippresenting them as a series of steps so that a reader can see how one stepleads to another for a complete discussion of the data analysis procedures. Thus, while the process begins inductively, deductive thinking also plays an important role as the analysis moves forward. Sometimes qualitative researchers write notes in margins of transcripts or observationalfield notes, or start recording general thoughts about the data at this stage. 1990 by the APA. Many qualitative researchers also usevisuals, figures, or tables as adjuncts to the discussions. Its basic premise is that an experiment needs to have sufficient sensitivity to detectthose effects it purports to investigate. 385 0 obj All groupsreceive a posttest. Identify whether the sampling design for this population is single stage or multistage (calledclustering). Organize and prepare the data for analysis. endobj We then examine methods for selecting a sample from the population and the arguments for and against each of the methods. The population is properly defined so that there is no ambiguity as to whether a given unit belongs to the population. Finally,less desirable is a nonprobability sample (or convenience sample), in which respondents are chosenbased on their convenience and availability. Expose the experimental group to the experimental treatment and administer no treatment or an alternative treatment to the control group. Creswell is a professor of family medicine and co-director of the Michigan Mixed Methods Research and Scholarship Program at the University of Michigan. Write thoughts in the margin. drawing on personal reflections and past. [The authors described the participants in this study.] In this interpretation, address whether the hypotheses or questionswere supported or whether they were refuted. setting.Interaction of Because of the characteristics of the setting of The researcher needs to replicate the study at later times tosetting and participants in an experiment, a researcher cannot determine if the same results occur as in the earlier time.treatment generalize to individuals in other settings.Interaction of Because results of an experiment are time-bound, ahistory and researcher cannot generalize the results to past or futuretreatment situations.SOURCE: Adapted from Creswell (2012). Abbreviate the topics as codes and write the codes next to the appropriate segments of the text. Try this preliminary organizing scheme to see if new categories and codes emerge. One or more groups receive theexperimental manipulation, or treatment, from the researcher. <> Analyze public documents (e.g., official memos, minutes, records, archival material). For example, suppose that a study is going to conduct a survey of high school students on their . This process is similar to developing operational definitions for constructs that are measured. Response bias is the effectof nonresponses on survey estimates (Fowler, 2009). While there are no hard and fast rules . 2. British. (Several of these tests are mentioned in Table 8.3,which was presented earlier.) Was a random selection method used?_____________ How will the participants be randomly assigned? 39 0 obj In a discussion about data collection forms, be specific about the types and include arguments concerning the strengths and weaknesses of each type, as discussed in Table 9.2. The following are a few advantages of using a descriptive research design: 1. Whenrandomly selecting people from a population, these characteristics may or may not be present in thesample in the same proportions as in the population; stratification ensures their representation. Cluster together similar topics. A log kept by the researchers would work equally well for this form of data.Data Analysis and Interpretation A methods discussion in a qualitative proposal needs also to specify the steps in analyzing thevarious forms of qualitative data. Tell the reader about the number of participants in each group and the systematic procedures fordetermining the size of each group. Identify whether the study will involve stratification of the population before selecting thesample. Multiple methods of data collection. Creswell (2012, p. 142) stated that sample is a sub-group of the target population that the researcher plans to study for generalizing about the target population. Thus, the total number of population was 49 students. According to Creswell (2014), phenomenology research typically ranges from three to ten participants (p. 189). These unusualforms create reader interest in a proposal and can capture useful information that observations andinterviews may miss. The ATF was then collected and scored while each subject completed a demographic data form and reviewed a set of instructions for viewing the videotape. In general, the intent is to make sense out of text and image data. Thousand Oaks, CA: Sage. the total of particles at a particular energy level. 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. <>4]/P 6 0 R/Pg 389 0 R/S/Link>> Identify the statistics and the statistical computer program for testing the major inferentialresearch questions or hypotheses in the proposed study. has been cited by the following article: TITLE: Knowledge of Diabetes Characteristics by Students at University of Tabuk, Saudi Arabia [Authors identified the research site and population.] Conduct chart audits. Prince 12.5 (www.princexml.com) 3536; Authors described the procedure used in the experiment. 3.2.1 Quantitative Research Methodology Creswell (2013) defines quantitative research as: "A means of testing objective theories by examining the relationship among variables. and writes the final report that includes. It may be appropriate to say that sample frame is an operationalized form of study population. Here the author underlines that "the types of data one would collect and analyze would differ considerably." . In this study, descriptive research is applied as the design. Quantitative is based on testing a theory, measured with numbers, Include creative data collection procedures that fall under the category of visual ethnography (Pink, 2001) and which might include living stories, metaphorical visual narratives, and digital archives (Clandinin, 2007). 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. <>18]/P 32 0 R/Pg 405 0 R/S/Link>> mixed methods research (Creswell, 2008; Cohen et al., 2007; Gliner et al., 2009; Kothari, 2010).

In a true experiment, the investigator randomly assigns the participants to treatmentgroups. In some quantitative projects, the analysis stops here with descriptiveanalysis, especially if the number of participants is too small for more advanced, inferential analysis. 70 0 obj Address whether the resultsmight have occurred because of inadequate experimental procedures, such as threats to internalvalidity, and indicate how the results might be generalized to certain people, settings, and times.Finally, indicate the implications of the results for the population studied or for future research.Example 8.6 An Experimental Method SectionThe following is a selected passage from a quasi-experimental study by Enns and Hackett (1990)that demonstrates many of the components in an experimental design. They can also decide how they want to collect the data, online, offline, or via phone. Bogdan and Biklen (1992) advanced topics that could be addressed insuch a proposal: Why was the site chosen for study? ]Concurrent and convergent validity (Campbell & Fiske, 1959) of these measures wasestablished through factor analysis, and was found to be at an adequate level. 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). <>371 0 R]/P 418 0 R/Pg 415 0 R/S/Link>> Potential threats to external validity also must be identified and designs created to minimize thesethreats. Specify the form of data collection. 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 .
