Find the most descriptive wording for your topics and turn them into categories. Comment about sensitive ethical issues that may arise (see Chapter 3). 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. Moreover, when qualitative researchersuse a theoretical lens, they can form interpretations that call for action agendas for reform and change.Researchers might describe how the narrative outcome will be compared with theories and thegeneral literature on the topic. 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). It also involvesdiscussing the sample for the study and the overall data collection and recording procedures. 3.2 Population and Sample . To this end, Creswell . Instead, Fowler (2009)suggested that these approaches are all misguided. For example, researchers interconnect themesinto a story line (as in narratives) or develop them into a theoretical model (as in grounded theory).Themes are analyzed for each individual case and across different cases (as in case studies) orshaped into a general description (as in phenomenology). Others exist that have been addressed adequately in qualitative books, suchas participatory action research (Kemmis & Wilkinson, 1998) or discourse analysis (Cheek, 2004).In the designs, researchers might study individuals (narrative, phenomenology); explore processes,activities, and events (case study, grounded theory); or learn about broad culture-sharing behavior ofindividuals or groups (ethnography). Inthe health sciences, a popular approach is to use predetermined codes based on the theory beingexamined. A separate section in a proposal may be composed to advance this threat. Define the exact type of threat and what potential issue it presents to your study. Discuss how you plan to address the threat in the design of your experiment. Cite references to books that discuss the issue of threats to validity, such as Cook and Campbell (1979); Shadish, Cook, & Campbell (2001); and Tuckman (1999).The Procedure A proposal developer needs to describe in detail the procedure for conducting the experiment.

Stratification means that specificcharacteristics of individuals (e.g., genderfemales and males) are represented in the sample and thesample reflects the true proportion in the population of individuals with certain characteristics. This design does not have a control group to compare with theexperimental group. In specific, measurable terms, what is the population for whom you will hold yourself accountable to meet desired outcomes? Thesis. In this study, descriptive research is applied as the design. Specify the form of data collection. Karen . US English. 6. ]Multiple regression and path analysis (Heise, 1969; Kerlinger & Pedhazur, 1973) were used toanalyze the 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. Still other independent variables can be statistically controlled, suchas demographics (e.g., gender or age). 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. Creswell, John W. 2013. This may be a single page with adividing line down the middle to separate descriptive notes (portraits of the participants, areconstruction of dialogue, a description of the physical setting, accounts of particular events, oractivities) from reflective notes (the researchers personal thoughts, such as speculation, feelings,problems, ideas, hunches, impressions, and prejudices Bogdan & Biklen, 1992, p. 121). Thismight be a discussion that mentions a chronology of events, the detailed discussion of several themes(complete with subthemes, specific illustrations, multiple perspectives from individuals, andquotations) or a discussion with interconnecting themes. Begin the discussion by reviewing the purpose of a surveyand the rationale for its selection for the proposed study. . Step 6. What activities will occur at the site during the research 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. The purposive sampling method is about selecting samples from the overall sample size based on the judgment of the survey taker or researcher. Indicate why a survey is the preferred type of data collection procedure for the study. United States. 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. endobj 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 baseline behavioris assessed, the treatment provided, and then the treatment is withdrawn. An ideal situationis to blend the general steps with the specific research strategy steps. As with the section on surveys, the intent here is to highlight key topics to be addressed in anexperimental methods section of a proposal. When you have completed this task for several participants, make a list of all topics. Again, permission to use any part of other instruments needs to be obtained. 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. The following sectionsdetail typical components. One approach is equating the groups at the outset of the experimentso that participation in one group or the other does not influence the outcome. Discuss the advantage of identifying attributes of a large populationfrom a small group of individuals (Fowler, 2009). Collect cell phone text messages (e.g., Twitter). 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). Plan to develop and use an interview protocol for asking questions and recording answers duringa qualitative interview. Fromhere, you can then determine the sample size needed for each group. Have a participant keep a journal or diary during the research study. Collect personal letters from participants. Experimental and quasi-experimental designs for research. i. (b)______ Check for response bias? Indicate the established validity and reliability of thescores on instruments, the individuals who developed them, and any permissions needed to use them. Also determine whether there was consistency in test administrationand scoring (Were errors caused by carelessness in administration or scoring? 2. 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. <> 7. Administer measures of the dependent variable or a variable closely correlated with the dependent variable to the research participants. Data Analysis Tell the reader about the types of statistical analysis that will be used during the experiment. When individuals are not randomly assigned, the procedure is called a quasi-experiment. With pre-experimental designs, the researcher studies a single group and provides anintervention during the experiment. 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.

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. Although the processes are similar, qualitative methods rely on text and image data, have unique steps in data analysis, and draw on diverse designs. Decide whether audience members areknowledgeable enough about the characteristics of qualitative research that this section is notnecessary. endobj This discussion involvesindicating the overall experiment type, citing reasons for the design, and advancing a visual model tohelp the reader understand the procedures. data for all the members of population. This questionnaire had been developed and tested at three other institutionsbefore its use at this college. 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. What specific steps will be taken in data analysis to do the following:(a)______ Analyze returns? 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. Thecollection procedures in qualitative research involve four basic types and their strengths andlimitations, as shown in Table 9.2. interprets the meaning of the information. This is followed by commentsabout potential threats to internal and external validity (and possibly statistical and construct validity)that relate to the experiment, the statistical analysis used to test the hypotheses or research questions,and the interpretation of the results. These tables require three elements. In wave analysis, the researcher examines returns on select items week by week todetermine if average responses change (Leslie, 1972). 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. 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. drawing on personal reflections and past. 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. Step 5. 6. Bogdan and Biklen (1992) advanced topics that could be addressed insuch a proposal: Why was the site chosen for study? Other independent variables maysimply be measured variables in which no manipulation occurs (e.g., attitudes or personalcharacteristics of participants). 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 . 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. Discuss a plan to provide a descriptive analysis of data for all independent and dependentvariables in the study. What would a visual model of this design look like?_____________ What instrument(s) will be used to measure the outcome in the study? The implicit statement of values condition used the sample interview only; the counselors values were therefore implicit in her responses. Have participants take photographs or videotapes (i.e., photo elicitation), and then interview them about the materials. 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. Design sensitivity: Statistical power for experimental research. Creswell is a professor of family medicine and co-director of the Michigan Mixed Methods Research and Scholarship Program at the University of Michigan. A researcher may decide not to match, however, because it is expensive,takes time (Salkind, 1990), and leads to incomparable groups if participants leave the experiment(Rosenthal & Rosnow, 1991). Population definition, the total number of people inhabiting a country, city, or any district or area. Read all the transcriptions carefully. To explain it better: Inother experiments, the researcher studies only one group in what is called a within-group design. <>35]/P 23 0 R/Pg 389 0 R/S/Link>> 3 0 obj 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. Thousand Oaks, CA: Sage. Examine physical trace evidence (e.g., footprints in the snow). Hand coding is a laborious and time-consuming process, even for data from a few individuals. A sample population is when a smaller group of a given population is formed. <> Using products such as these, researchers cancreate their own surveys quickly using custom templates and post them on websites or e-mail them forparticipants to complete. 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. Between 2019 and 2020 the population of Creswell, OR grew from 5,356 to 5,445, a 1.66% increase and its median household income grew from $61,149 to $72,305, a 18.2% increase.

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. participants from the study population in an unbiased manner, the standardized questionnaire or intervention they receive, and statistical methods used to . 16 0 obj We then examine methods for selecting a sample from the population and the arguments for and against each of the methods. 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. 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. ]Data were collected by means of a questionnaire containing 116 items. Occasional missing data on particular items were handled by a pairwise deletion procedure. After viewing the videotape that corresponded to their experimental assignment, participants completed the dependent measures and were debriefed. One chapter, for example, illustrates the conventions for displayingdata on line graphs. 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. Population and Sample 3.2.1. 380-381). In the natural setting, the researchers have face-to-face interaction, often over time. Look for ways of reducing your total list of categories by grouping topics that relate to each other. endobj population definition: 1. all the people living in a particular country, area, or place: 2. all the people or animals of. 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. Creswell's definition of Qualitative Research: Qualitative research is an inquiry process of understanding based on distinct methodological traditions of inquiry that explore a social or human problem. 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. ^d)bD]qiN0#IbGd5~m (m$$z9YY+N&1, Nestor Asiamah, Henry Kofi Mensah, and Eric Fosu Oteng-Abayie, General, Target, and Accessible Population: Demystifying the Concepts for Effective Sampling.

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. The outcomes are thus dropouts or compare those who drop out with those unknown for these individuals. 66 0 obj If so, how?_____________ How many people will be in the sample? There are two types of threats to validity: (a)internal threats and (b) external threats. Estimating population parameters from sample statistics. 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. To get a significant result, certain method and design should be used in doing the study. Make a final decision on the abbreviation for each category and alphabetize these codes.

Descriptive research definition: Descriptive research is defined as a research method that describes the characteristics of the population or phenomenon studied. 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. Step 1: Report on samplenumber who returned and did not returncan . Conduct different types of interviews: e-mail or Internet, face-to-face, focus group, online focus group, and telephone interviews. In a true experiment, the investigator randomly assigns the participants to treatmentgroups. When one modifies an instrument or combines instruments in a study, the original validity andreliability may not hold for the new instrument, and it becomes important to reestablish validity andreliability during data analysis. . US English. Now these discussions are less frequentlyfound in the literature and there is some consensus as to what constitutes qualitative inquiry. 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. <>368 0 R]/P 416 0 R/Pg 415 0 R/S/Link>> endobj AUTHORS: Timothy Adu Gyamfi, Edward Nana-Addy, Wiliam Gyadu .

How will they be addressed?_____________ Will a pilot test of the experiment be conducted?_____________ What statistics will be used to analyze the data (e.g., descriptive and inferential)?_____________ How will the results be interpreted?Participants Readers need to know about the selection, assignment, and number of participants who will takepart in the experiment. Compare the performance of the experimental and control groups on the posttest(s) using tests of statistical significance. Then, he suggested going to a table found in many survey books (see Fowler, 2009)to look up the appropriate sample size. The majority of thesewere Likert-like items based on a scale from a very small extent to a very great extent.Other questions asked for factual information, such as ACT scores, high school grades, andparents educational level. The researcher also should report on the materials used for theexperimental treatment (e.g., the special program or specific activities given to the experimentalgroup). [Validity and reliability were addressed. 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). Response bias is the effectof nonresponses on survey estimates (Fowler, 2009). 386 0 obj These lessons could be the researchers personal interpretation, couched inthe understanding that the inquirer brings to the study from a personal culture, history, andexperiences.
