As shown inTable 9.4, Tesch (1990) provided the eight steps typically used in forming codes.Table 9.4 Teschs Eight Steps in the Coding Process 1. There are two types of threats to validity: (a)internal threats and (b) external threats. Here are somesuggestions for developing ideas about variables in a proposal: Clearly identify the independent variables in the experiment (recall the discussion of variables inChapter 3). <>/Metadata 2 0 R/Outlines 5 0 R/Pages 3 0 R/StructTreeRoot 6 0 R/Type/Catalog/ViewerPreferences<>>> Foundations of behavioral statistics: An insight-based approach. According to Creswell (2014), phenomenology research typically ranges from three to ten participants (p. 189). For further types of statistical tests, readers are referred to statistics methodsbooks, such as Gravetter and Wallnau (2009).Step 6. Researchersoften engage in multiple observations during the course of a qualitative study and use anobservational protocol for recording information while observing. It involves some type of comparison or contrast and attempts to discover relationships between existing non-manipulated variables. 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. regress toward the mean. Even if an interview is taped, I recommend that researcherstake notes in the event that recording equipment fails. Organize and prepare the data for analysis. who continuein terms of the outcome.Diffusion of treatment Participants in the control and experimental groups The researcher can keep the two groups as separate communicate with each other. He reviews thebasics about descriptive statistics (location, dispersion, shape), about relationships among variablesand statistical significance, about the practical significance of results, and about more advancedstatistics such as regression, ANOVA, the general linear model, and logistic regression. population might tell us if we asked every member of the larger population the same questions" (1). The median on the final sample was checked and a few participants recategorized by the final median split, which resulted in 12 or 13 participants per cell. Numerous examples of this formatappear in scholarly journals, and these examples provide useful models. 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 . For visual data, asketchbook of ideas can begin to take shape. Identify the selection process for individuals. Thus, mysuggestions about this section of a proposal are as follows: Review the needs of potential audiences for the proposal. 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. Then the sample of this research was 33 students. endobj 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. even though it's . can influence how both groups score on the outcomes. When you have completed this task for several participants, make a list of all topics. Despite these analytic differences depending on the type of strategy used, qualitative inquirersoften use a general procedure and convey in the proposal the steps in data analysis. 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). Creswell (2002) noted that quantitative research is the process of collecting, analyzing, interpreting, and writing the results of a study, while qualitative research is . 380-381). An interpretation in quantitative research means that the researcherdraws conclusions from the results for the research questions, hypotheses, and the larger meaning ofthe results. Both groups are administered both a pretest and a posttest, but the treatment is providedonly to experimental Group A.Group A R_____O_____X_____OGroup B R_____O_____OPosttest-Only Control-Group DesignThis design controls for any confounding effects of a pretest and is a popular experimental design.The participants are randomly assigned to groups, a treatment is given only to the experimentalgroup, and both groups are measured on the posttest.Group A R X O___________ ___________Group B R_______________OSolomon Four-Group Design A special case of a 2 X 2 factorial design, this procedure involves the random assignment ofparticipants to four groups. An alternative check for response bias is to contact afew nonrespondents by phone and determine if their responses differ substantially from respondents.This constitutes a respondent-nonrespondent check for response bias. In some quantitative projects, the analysis stops here with descriptiveanalysis, especially if the number of participants is too small for more advanced, inferential analysis. which the inquirer: analyzes and codes the data for description. 3536; Authors described the procedure used in the experiment. 2. Report information about the number of members of the sample who did and did not returnthe survey. 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). endobj Cluster sampling is ideal when it is impossible or impractical to compile a list of theelements composing the population (Babbie, 2007). This involves transcribing interviews, opticallyscanning material, typing up field notes, cataloguing all of the visual material, and sorting andarranging the data into different types depending on the sources of information. Researchers can select participants by random selection or random sampling. During the process of research, the investigator may collect qualitative documents. The number of the selected population will be number of students ranging on 17-18 years old. Design sensitivity: Statistical power for experimental research. If audiotaping is used, researchers need to planin advance for the transcription of the tape. A sound research plan calls for a thorough discussion aboutthe instrument or instrumentstheir development, their items, their scales, and reports of reliabilityand validity of scores on past uses. Have a participant keep a journal or diary during the research study. Collect personal letters from participants. This call for descriptive analysis is consistent with the recentAPA Publication Manual (APA, 2010). 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. This codebook can evolve and change during astudy based on close analysis of the data when the researcher is not starting from an emerging codeperspective. Population is the entire pool from which a statistical sample is drawn. Thisoften leads to compromises in the researchers ability to disclose information and raises issues of animbalance of power between the inquirers and the participants. In many experiments, however, only a convenience sample is possible because theinvestigator must use naturally formed groups (e.g., a classroom, an organization, a family unit) orvolunteers. British. When studying bullying in the schools, I might code some segments as attitudes toward oneself. This code would be expected in a study about bullying in the schools. Codes that are surprising and that were not anticipated at the beginning of the study. has been cited by the following article: TITLE: Motivational Strategies to Improve Artisan's Productivity in the Construction Industry in Ghana. uuid:dd8cd074-b0e5-11b2-0a00-b05ae0a4fc7f Collect sounds, smells, tastes, or any stimuli of the senses.SOURCE: Adapted from Creswell (2013).Data Recording Procedures Before entering the field, qualitative researchers plan their approach to data recording. The first two programs weredeveloped in Germany and the third in Australia. These statistics are means, standard deviations, and ranges. Interpreting Results The final step in an experiment is to interpret the findings in light of the hypotheses or researchquestions set forth in the beginning. Provide a diagram or a figure to illustrate the specific research design to be used. The desire to draw inferences about a large population from a subset of that population is the main concern for a researcher. The purpose statement also includes brief information about direction, scope, and where the data will come from. In research, population is a term used to describe a group of living organisms that share a particular area. %PDF-1.7 % The following are a few advantages of using a descriptive research design: 1. (Several of these tests are mentioned in Table 8.3,which was presented earlier.) Delimitations are the exact opposite of limitations. Indicate the major content sections in the instrument, such as the cover letter (Dillman, 2007,provides a useful list of items to include in cover letters), the items (e.g., demographics, attitudinalitems, behavioral items, factual items), and the closing instructions. The data collection steps include setting the boundaries for the study, collectinginformation through unstructured or semi structured observations and interviews, documents, andvisual materials, as well as establishing the protocol for recording information. Step 2. DEFINING SURVEYS AND EXPERIMENTSA survey design provides a quantitative or numeric description of trends, attitudes, or opinions of apopulation by studying a sample of that population. <>1]/P 13 0 R/Pg 389 0 R/S/Link>> Design a plan for the procedures to be used in a survey study. I tend to think about codes as falling into three categories: Codes on topics that readers would expect to find, based on the past literature and common sense. Another definition comes from Creswell (2012) who notes that population is a group of individuals who have the same characteristics. 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. Both groups take a pretest and posttest. 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. How was it operationalized?_____________ Will variables be covaried in the experiment? 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. A more direct definition is the method used for selecting a given number of people (or things) from a population (2). 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). He has written numerous journal articles and 27 books on mixed methods research, research methods, and qualitative research. Examine autobiographies and biographies. Backyard research (Glesne & Peshkin,1992) involves studying researchers own organization, or friends, or immediate work setting. 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). ]Data were collected by means of a questionnaire containing 116 items. See more. Typically these observations are open-ended in that the researchers ask general questions of the participants allowing the participants to freely provide their views. 66 0 obj and writes the final report that includes. Descriptive research definition: Descriptive research is defined as a research method that describes the characteristics of the population or phenomenon studied. Gather field notes by conducting an observation as an observer. A single-stage sampling procedure is one inwhich the researcher has access to names in the population and can sample the people (or otherelements) directly. endstream 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. 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. Grounded theoryhas systematic steps (Corbin & Strauss, 2007; Strauss & Corbin, 1990, 1998). 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. Bowling (2002) explains that methodology is the complete structure of the research study; the size and . Examples of delimitation are using only results from one . The descriptive research method primarily focuses on describing the nature of a demographic segment, without focusing on "why" a particular phenomenon occurs. 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.

The constructs were represented by 25measuresmultiple items combined on the basis of factor analysis to make indicesand 27measures were single item indicators. In many qualitative studies, inquirers collectmultiple forms of data and spend a considerable time in the natural setting gathering information. This chapter addressesthese important components of writing a good qualitative methods section into a proposal. 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). The following sectionsdetail typical components. 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. 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. 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 . Read all the transcriptions carefully. <>63 0 R]/P 69 0 R/S/Link>> The researcher builds a complex, holistic picture, analyzes words, reports detailed views of informants, and conducts the study in a natural . One independent variable must be the treatment variable. Then, he suggested going to a table found in many survey books (see Fowler, 2009)to look up the appropriate sample size. Perhaps jot down some ideas as they come to mind as you read. Therefore, only women were analyzed in this study.During April 1979, 169 women returned questionnaires.

Then the researcherdraws a figure to illustrate the design, using appropriate notation. 1 participants from the study population in an unbiased manner, the standardized questionnaire or intervention they receive, and statistical methods used to . Still other independent variables can be statistically controlled, suchas demographics (e.g., gender or age). This analysis should indicate the means, standard deviations, and range ofscores for these variables. I n qualitative interviews, the researcher conducts face-to-face interviews with participants, telephone interviews, or engages in focus group interviews with six to eight interviewees in each group. Research on attrition indicates that males and females drop out of college for different reasons (Bean, 1978, in press; Spady, 1971). 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). One chapter, for example, illustrates the conventions for displayingdata on line graphs. Although the researcher still needs to go through each line of text(as in hand coding by going through transcriptions) and assign codes, this process may be faster andmore efficient than hand coding. How will it be measured? For example, when studying a sensitive topic, it isnecessary to mask names of people, places, and activities. Include data collection types that go beyond typical observations and interviews. endobj 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). Administer measures of the dependent variable or a variable closely correlated with the dependent variable to the research participants. Discuss whether it is an instrument designed forthis research, a modified instrument, or an intact instrument developed by someone else. endobj Look for ways of reducing your total list of categories by grouping topics that relate to each other. Most of the surveys mentioned above seek to monitor trends over time. 2021-03-30T12:20:34-07:00 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.
