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). Design and analysis: A researchers handbook (4th ed.). endobj The questioning approach is alsoused in transformative approaches to qualitative research. In Table 8.3, I show how the factors, in combination, lead to the selection of a number ofcommon statistical tests. Most of the surveys mentioned above seek to monitor trends over time. They do not tend to use or rely on questionnaires or instruments developed by other researchers. 15 0 obj population definition: 1. all the people living in a particular country, area, or place: 2. all the people or animals of. The intent of a codebook is toprovide definitions for codes and to maximize coherence among codesespecially when multiplecoders are involved.

Indicate the number of people who will test the instrument and the plansto incorporate their comments into final instrument revisions. The STANDS4 Network . If necessary, recode your existing data. Further, consider whether the variables will be measured on an instrument as acontinuous score (e.g., age from 18 to 36) or as a categorical score (e.g., women = 1, men = 2).Finally, consider whether the scores from the sample might be normally distributed in a bell-shapedcurve if plotted out on a graph or non-normally distributed. Fowler (2009) identified the following types: mail,telephone, the Internet, personal interviews, or group administration (see also Fink, 2012; Krueger &Casey, 2009). 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 codebook would provide a list of codes, a code label for each code, abrief definition of it, a full definition of it, information about when to use the code and when not to useit, and an example of a quote illustrating the code. Step 4. One further issue about coding is whether the researcher should (a) develop codes only on thebasis of the emerging information collected from participants, (b) use predetermined codes and thenfit the data to them, or (c) use some combination of emerging and predetermined codes. Writing Exercises 1. Why was it chosen? narrative research, ethnography. 2021-03-30T12:20:34-07:00 has been cited by the following article: TITLE: Knowledge of Diabetes Characteristics by Students at University of Tabuk, Saudi Arabia It could also be a meaning derived from a comparison of the findings with informationgleaned from the literature or theories. 3.1 Research Design. For example,the questions may change, the forms of data collection may shift, and the individuals studied andthe sites visited may be modified. According to Creswell (2014), phenomenology research typically ranges from three to ten participants (p. 189). Compare the performance of the experimental and control groups on the posttest(s) using tests of statistical significance. Go through it, asking yourself, What is this about? Do not think about the substance of the information but its underlying meaning.

Except for a limited discussion aboutdata analysis and an interpretation section found in the discussion of their article, their approachcontains the elements of a good method section for an experimental study.Method Participants The participants were 150 undergraduate women enrolled in both lower-and upper-division courses in sociology, psychology, and communications at a midsized university and a community college, both on the west coast. 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). (Eds.). Creswell et al. A parameter is a measure that describes the whole population (e.g., population mean). An effect size identifies thestrength of the conclusions about group differences or the relationships among variables inquantitative studies. It is also helpful to comment on the reliability and value of the data sources. Chicago: Rand McNally. Creswell is a city located in Lane County Oregon.With a 2023 population of 5,824, it is the 92nd largest city in Oregon and the 6016th largest city in the United States. There are additional ways to determine ifthe scores are normally distributed (see Creswell, 2012). 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 . For visual materials, some form of system is needed to organize the materials so that they can be easily retrieved. 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. 3536; Authors described the procedure used in the experiment. Washington DC: Sage. 3. This descriptive methodology focuses more on the "what" of the research subject than the "why" of the research subject. Find the most descriptive wording for your topics and turn them into categories. Also, in large databases, the researcher can quickly locate allpassages (or text segments) coded the same and determine whether participants are responding to acode idea in similar or different ways. They may use a protocolan instrument for collecting databut the researchers are the ones who actually gather the information. Response bias is the effectof nonresponses on survey estimates (Fowler, 2009). Asidefrom the small number that characterizes qualitative research, how many sites and participants shouldyou have? Step 2. 38 0 obj The statistical significance testing reports anassessment as to whether the observed scores reflect a pattern other than chance. Although this book cites many applications in literacy, it has broad application inthe social and human sciences.Thompson, B. 2021-03-30T12:20:34-07:00 endobj Descriptive research definition: Descriptive research is defined as a research method that describes the characteristics of the population or phenomenon studied. Thesis. Step 3. The sample size formula for the infinite population is given by: S S = Z 2 P ( 1 P) C 2. Population is the entire pool from which a statistical sample is drawn. The inferential questions or hypothesesrelate variables or compare groups in terms of variables so that inferences can be drawn from thesample to a population. 2. Include sample items from the instrument so that readers can see the actual items used. mixed methods research (Creswell, 2008; Cohen et al., 2007; Gliner et al., 2009; Kothari, 2010). Do results correlate with other results? Beyond identifying the themes during the coding process, qualitative researchers can do much withthemes to build additional layers of complex analysis. This involves reporting multiple perspectives, identifying the many factorsinvolved in a situation, and generally sketching the larger picture that emerges. In these field notes, the researcher records, in an unstructured or semistructured way (using some prior questions that the inquirer wants to know), activities at the research site. United States.

The discussion in your proposal about qualitative data analysis might beginwith several general points about the overall process: Data analysis in qualitative research will proceed hand-in-hand with other parts of developingthe qualitative study, namely, the data collection and the write-up of findings. endobj Write thoughts in the margin. The chapter presents an excellent summary of types ofdesigns, their threats to validity, and statistical procedures to test the designs. [Authors described the three treatment conditions variables manipulated in the study.] What specific steps will be taken in data analysis to do the following:(a)______ Analyze returns? It is for the benefit of the population that researches are done. 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. 380-381). (e)______ Check for reliability of scales? (2009). A brief proposal might need to be developed and submittedfor review to gatekeepers. 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).

Their study addressed thegeneral issue of matching client and counselor interests along the dimensions of attitudes towardfeminism. 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). <> Who developed the instrument?_____________ What are the content areas addressed in the survey? Creswell (2012:3) states research designs are the specific procedures involved in the research process: data collection, data analysis, and report writing. These unusualforms create reader interest in a proposal and can capture useful information that observations andinterviews may miss. Identify whether the study will involve stratification of the population before selecting thesample. Also, indicate the practical significance by reporting effect sizes andconfidence intervals. With this defined, we examine the population subsets and what characterizes them. 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. Like this book? endobj For example, examine the compendium of types of data in Table 9.3 that can beused, to stretch the imagination about possibilities, such as gathering sounds or tastes, or usingcherished items to elicit comments during an interview. has been cited by the following article: TITLE: Motivational Strategies to Improve Artisan's Productivity in the Construction Industry in Ghana. Naturally, their scores will probably extreme scores as entering characteristics for the change during the experiment. While interviews aregoing on, for example, researchers may be analyzing an interview collected earlier, writing memosthat may ultimately be included as a narrative in the final report, and organizing the structure of thefinal report. First, determine themargin of error you are willing to tolerate (say +/4% confidence interval). 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. 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 following sectionsdetail typical components. Foundations of behavioral statistics: An insight-based approach. In some quantitative projects, the analysis stops here with descriptiveanalysis, especially if the number of participants is too small for more advanced, inferential analysis. The words you are searching are inside this book. As mentioned in Chapter 1, I recommend that qualitativeresearchers choose from among the possibilities, such as narrative, phenomenology, ethnography,case study, and grounded theory. Thisplan might involve handouts, lessons, and special written instructions to help students in thisexperimental group learn how to study a subject using computers. It may be appropriate to say that sample frame is an operationalized form of study population. As a check on participants perception of the experimental manipulation and as an assessment of participants perceived similarity to the three counselors, two subscales of Berryman-Fink and Verderbers (1985) Attributions of the Term Feminist Scale were revised and used in this study as the Counselor Description Questionnaire (CDQ) and the Personal Description Questionnaire (PDQ). The target population is the subset of people for whom the program is designed, that you will actively recruit and retain, and for whom you will hold yourselves accountable for achieving outcomes. 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). Also mention reliability checks forthe internal consistency of the scales (i.e., the Cronbach alpha statistic). Form these topics into columns, perhaps arrayed as major, unique, and leftover topics. In many qualitative studies, inquirers collectmultiple forms of data and spend a considerable time in the natural setting gathering information. Pretests and treatments are varied for the four groups. Indicate steps taken to obtain permission from the institutional review board (IRB) (see Chapter4) to protect the rights of human participants. Also mention whether scores resulting from past use of the instrument demonstrate reliability.Look for whether authors report measures of internal consistency (Are the items responses consistentacross constructs?) I would suggest that you advance these seven steps in your methods section of yourproposal and give concrete illustrations of potential codes and themes that might emerge in yourstudy. Discuss the advantage of identifying attributes of a large populationfrom a small group of individuals (Fowler, 2009). Thoroughly discuss the materials used for the experimental treatment. Based on the assumption that those who returnsurveys in the final weeks of the response period are nearly all nonrespondents, if the responses beginto change, a potential exists for response bias. 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. Using an Internet survey and administering it online has been discussed extensively inthe literature (Nesbary, 2000; Sue & Ritter, 2012). Fortunately, there is somecommon agreement today about the core characteristics that define qualitative research. The population at the 2010 census was 5,031. What is the impression of the overall depth, credibility, and use of theinformation? Susan Neuman and Sandra McCormick have edited a useful, practical guide to the design of single-subject research. Mia. 16 0 obj A population can . 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. Consider the following: Name the survey instrument used to collect data. Refer to Table 8.4 after you complete your plan to determine if all questions have been addressed adequately.ADDITIONAL READINGSCampbell, D. T., & Stanley, J. C. (1963). Thus, interpretation in qualitative research cantake many forms; be adapted for different types of designs; and be flexible to convey personal,research-based, and action meanings. Also specify whether you will use a qualitative computer data analysis program to assist you inanalyzing the data (or whether you will hand code the data). Indicate the established validity and reliability of thescores on instruments, the individuals who developed them, and any permissions needed to use them. (1995). It involves taking text data or pictures gathered during data collection,segmenting sentences (or paragraphs) or images into categories, and labeling those categories with aterm, often a term based in the actual language of the participant (called an in vivo term). The interview protocol needs to include the followingcomponents: A heading (date, place, interviewer, interviewee) Instructions for the interviewer to follow so that standard procedures are used from one interview to another The questions (typically an ice-breaker question at the beginning followed by four to five questions that are often the subquestions in a qualitative research plan, followed by some concluding statement or a question, such as, Who should I visit with to learn more about my questions? Probes for the four to five questions, to follow up and ask individuals to explain their ideas in more detail, or to elaborate on what they have said Spaces between the questions to record responses A final thank-you statement to acknowledge the time the interviewee spent during the interview Researchers typically develop a log to keep a record of documents collected for analysis in a qualitative study. 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. Study population is a subset of the target population from which the sample is actually selected. 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). Human populations . Identify the selection process for individuals. [The authors described the participants in this study.] A single-subject design or N of 1 design involves observing the behavior of a singleindividual (or a small number of individuals) over time. Guest and colleagues (2012)discussed and illustrated the use of codebooks in qualitative research. 56 0 obj Thisoften leads to compromises in the researchers ability to disclose information and raises issues of animbalance of power between the inquirers and the participants. The Definition. Thus, the total number of population was 49 students. Tell the reader about the number of participants in each group and the systematic procedures fordetermining the size of each group. Step 5. These involve telling the reader about the design being usedin the study and, in this case, the use of qualitative research and its basic intent. 5. 3.2.1 Population According to Creswell (2012, p. 142), population is a group of individuals who have the same characteristics. 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. This calculation involves thefollowing: A consideration of the level of statistical significance for the experiment, or alpha The amount of power desired in a studytypically presented as high, medium, or lowfor the statistical test of the null hypothesis with sample data when the null hypothesis is, in fact, false The effect size, the expected differences in the means between the control and experimental groups expressed in standard deviation units Researchers set values for these three factors (e.g., alpha = 0.05, power = 0.80, and effect size =0.50) and can look up in a table the size needed for each group (see Cohen, 1977; Lipsey, 1990). 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. 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). The dropout rate the previous year was 25%. Gather field notes first by observing as a participant-outsider and then moving into the setting and observing as a participant- insider. Inte rvie ws Conduct an unstructured, open-ended interview and take interview notes. 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. <>1]/P 13 0 R/Pg 389 0 R/S/Link>> Instead, Fowler (2009)suggested that these approaches are all misguided. Many designs exist, such as the 28approaches identified by Tesch (1990), the 22 types in Wolcotts (2009) tree, and the five traditionsto qualitative inquiry by Creswell (2013). <>62 0 R]/P 67 0 R/S/Link>> 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. Tavallaei and Talib (2010) further note that qualitative approaches are utilized "when the researcher's variables are unclear and unknown and when a relevant theory base is missing in any sense" (p. 571).
