definition of population by creswell

The STANDS4 Network . <>371 0 R]/P 418 0 R/Pg 415 0 R/S/Link>> census: [noun] a count of the population and a property evaluation in early Rome. With randomselection or random sampling, each individual has an equal probability of being selected from thepopulation, ensuring that the sample will be representative of the population (Keppel & Wickens,2003). Here are essential aspects of the population andsample to describe in a research plan: Identify the population in the study. In general, the intent is to make sense out of text and image data. ]SOURCE: Enns and Hackett (1990). 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. Examine autobiographies and biographies. Have a participant keep a journal or diary during the research study. Collect personal letters from participants. In a multistage or clustering procedure, the researcher first identifies clusters(groups or organizations), obtains names of individuals within those clusters, and then samples withinthem. There are three kinds of survey media that used in survey research, that are written survey, verbal survey and mix mode survey. 66 0 obj The inferential questions or hypothesesrelate variables or compare groups in terms of variables so that inferences can be drawn from thesample to a population. Step 3. A homogeneous sample of 135women who were 25 years old or younger, unmarried, full-time U.S. citizens, and Caucasianwas selected for this analysis to exclude some possible confounding variables (Kerlinger,1973).Of these women, 71 were freshmen, 55 were sophomores, and 9 were juniors. 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. Because text and image data are so dense and rich, not all of the information can be used in aqualitative study. In this section of the chapter,I review these components as well as information about the experimental design and statisticalanalysis. This procedure is especially helpful in dissertations in which investigators test large-scale models. endobj How to pronounce Creswell? In qualitative research, theimpact of this process is to aggregate data into a small number of themes, something like five to seventhemes (Creswell, 2013). Thisoften leads to compromises in the researchers ability to disclose information and raises issues of animbalance of power between the inquirers and the participants. 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. This call for descriptive analysis is consistent with the recentAPA Publication Manual (APA, 2010). 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. Gibbs et al (20 07) and Patton (2002) demonstrated that there were a number of methods the research ers would . McMillian and Schumaker (2010) use the term sampling frame to describe a smaller subset of the general population for a study. When individuals are not randomly assigned, the procedure is called a quasi-experiment. In quasi-experiments, the investigator uses control and experimental groups butdoes not randomly assign participants to groups (e.g., they may be intact groups available to theresearcher). Population is the entire pool from which a statistical sample is drawn. endobj 2. and Creswell, J.D. Creswell et al. <>70 0 R]/P 32 0 R/S/Link>> The population is properly defined so that there is no ambiguity as to whether a given unit belongs to the population. The basic idea behind these programs is that using the computer is an efficient means forstoring and locating qualitative data. Thus, mysuggestions about this section of a proposal are as follows: Review the needs of potential audiences for the proposal. From my review of many qualitative research studies I have found narrative research toinclude one or two individuals; phenomenology to typically range from three to ten; grounded theory,twenty to thirty; ethnography to examine one single culture-sharing group with numerous artifacts,interviews, and observations; and case studies to include about four to five cases. A standardnotation system needs to be used in this figure. These four topics generally are sufficient. Sometimes qualitative researchers write notes in margins of transcripts or observationalfield notes, or start recording general thoughts about the data at this stage. If a random assignment is made, discuss how the project will randomly assignindividuals to the treatment groups. An ideal situationis to blend the general steps with the specific research strategy steps. <>62 0 R]/P 67 0 R/S/Link>> They can also decide how they want to collect the data, online, offline, or via phone. Will the study be disruptive?How will the results be reported? Abbreviate the topics as codes and write the codes next to the appropriate segments of the text. Docume nts Keep a journal during the research study. US English. 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. 421 0 obj Population Research: Convenience Sampling Strategies - Volume 36 Issue 4. Definition. The software program then can generate results and report them back to theresearcher as descriptive statistics or as graphed information. This chapter addressesthese important components of writing a good qualitative methods section into a proposal. One group, for example,may participate in a special computer-assisted learning plan used by a teacher in a classroom. Bogdan and Biklen (1992) advanced topics that could be addressed insuch a proposal: Why was the site chosen for study? These tables require three elements. What general ideas are participants saying? Then the sample of this research was 33 students. With pre-experimental designs, the researcher studies a single group and provides anintervention during the experiment. Thisaspect of the methods is more than merely advancing biases and values in the study, but how thebackground of the researchers actually may shape the direction of the study.Holistic account: Qualitative researchers try to develop a complex picture of the problem orissue under study. In a study of leadership in nonprofit organizations, I might learn about the impact of geo-warming on the building of the organization and how this shapes the location and proximity of individuals to one another. 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). 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. 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. Like this book? (Eds.). A number ofauthors of introductory texts convey these characteristics, such as Creswell (2013), Hatch (2002), andMarshall and Rossman (2011). 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. The fact that individuals were reminded of past traumatic incidentsretriggering prompted us to use the term as an important code and ultimately a theme in our 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. [The authors described the participants in this study.] British. Theseexperiences may involve participation in the setting, past educational or work experiences, or culture,ethnicity, race, SES, or other demographics that tie the researchers directly to the study. Instead, Fowler (2009)suggested that these approaches are all misguided. <> To get a significant result, certain method and design should be used in doing the study. 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. It may involve discussing theoretical andpractical consequences of the results. 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. 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. Forexample, in a repeated measures design, participants are assigned to different treatments at differenttimes during the experiment. Third, estimate the percentage of your sample that will respond in a givenway (50% with 50/50 being the most conservative because people could respond either way). 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. Instruments Manipulation checks. Creswell (2002) noted that quantitative research is the process of collecting, analyzing, interpreting, and writing the results of a study, while qualitative research is . Time, money, and difficulty or ease in reaching your target population will shape your sampling decisions. 39 0 obj 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. Who developed the instrument?_____________ What are the content areas addressed in the survey? Throughoutthe book, he brings in practical examples to illustrate his points.CHAPTER NINEQualitative MethodsQualitative methods demonstrate a different approach to scholarly inquiry than methods of quantitative research. Survey research methods (4th ed.). Descriptive research definition: Descriptive research is defined as a research method that describes the characteristics of the population or phenomenon studied. Sage, Los Angeles. Examine possessions or ritual objects. Nestor Asiamah, Henry Kofi Mensah, and Eric Fosu Oteng-Abayie Sophisticated qualitative studies go beyonddescription and theme identification and form complex theme connections. Descriptive research definition: Descriptive research is defined as a research method that describes the characteristics of the population or phenomenon studied. Third edition. The experimenter, an advanced doctoral student in counseling psychology, greeted each subject, explained the purpose of the study as assessing students reactions to counseling, and administered the ATF. 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. Audiovisual Materials Examine photographs or videotapes. <>39]/P 24 0 R/Pg 389 0 R/S/Link>> In anappendix to the proposal, attach sample items or the entire instrument. For all three approaches, Creswell includes a preliminary consideration of philosophical assumptions, a review of the literature, an assessment of the use of theory in research . 3 0 obj Chapter 1 opens with -- definition of research approaches and the . A Study of Faculty Acceptance of a Faculty Information Survey (1974) John Ward Creswell is an American academic known for his work in mixed methods research. AppendPDF Pro 6.3 Linux 64 bit Aug 30 2019 Library 15.0.4 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. Indicate the type or types of data to be collected. Spanning over 2 miles, Creswell has a population . Experimental and quasi-experimental designs for research. 420 0 obj Still other independent variables can be statistically controlled, suchas demographics (e.g., gender or age). They may use a protocolan instrument for collecting databut the researchers are the ones who actually gather the information. [Authors discussed the instrument. Thisintroduces a range of strategic, ethical, and personal issues into the qualitative research process(Locke, Spirduso, & Silverman, 2013). 12 0 obj 385 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. Dictionary of Current English (1986:720), research is defined as "systematic investigation . definition of population by creswell in . Thisanalysis is useful in designing detailed descriptions for case studies, ethnographies, and narrativeresearch projects. US English. Now take this list and go back to your data. A confidence interval is a range of values (an interval) thatdescribes a level of uncertainty around an estimated observed score. 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. <> The desire to draw inferences about a large population from a subset of that population is the main concern for a researcher. Intervening variables significantly related to intent to leavewere then regressed on organizational variables, personal variables, environmental variables,and background variables. This is an essentialchapter for students beginning their study of experimental studies.Fowler, F. J. Have participants take photographs or videotapes (i.e., photo elicitation), and then interview them about the materials. The design also includes the specific type of experiment, such as a pre-experimental, quasi-experimental, true experiment, or single-subject design. P = Percentage of Population. This involves reporting multiple perspectives, identifying the many factorsinvolved in a situation, and generally sketching the larger picture that emerges. Mark Lipsey has authored a major book on the topics of experimental designs and statistical powerof those designs. Inductive and deductive data analysis: Qualitative researchers build their patterns, categories, and themes from the bottom up by organizing the data into increasingly more abstract units of information. <>/P 36 0 R/S/Link>> United States. 1 0 obj In writing a procedure for a qualitative proposal, consider the following research tips: Identify the specific design that you will be using and provide references to the literature that discusses the approach. Provide some background information about the design, such as its discipline origin, the applications of it (preferably to your field), and a brief definition of it (see Chapter 1 for the five designs). Discuss why it is an appropriate strategy to use in the proposed study. Identify how the use of the design will shape many aspects of the design process, such as the title, the problem, the research questions, the data collection and analysis and report write-up.The Researchers Role As mentioned in the list of characteristics, qualitative research is interpretative research; theinquirer is typically involved in a sustained and intensive experience with participants. In the natural setting, the researchers have face-to-face interaction, often over time. When researchers collect data at theirown workplace (or when they are in a superior role to participants), the information may beconvenient and easy to collect, but it may not be accurate information and may jeopardize the roles ofthe researchers and the participants. ]Concurrent and convergent validity (Campbell & Fiske, 1959) of these measures wasestablished through factor analysis, and was found to be at an adequate level. the experimental treatment.Maturation Participants in an experiment may mature or change The researcher can select participants who mature or during the experiment, thus influencing the results. 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). Theproposal should identify what data the researcher will record and the procedures for recording data. The intent of a codebook is toprovide definitions for codes and to maximize coherence among codesespecially when multiplecoders are involved. If necessary, recode your existing data. Delimitations are the exact opposite of limitations. Chicago: Rand McNally. 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. and Creswell, J.D. <>27]/P 21 0 R/Pg 389 0 R/S/Link>> 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. This figure suggests a linear, hierarchical approach building from the bottom to the top, but I see itas more interactive in practice; the various stages are interrelated and not always visited in the orderpresented. Creswell, Fetters and Ivankova (2004:7) argue that mixed methods research is more than . Inthis way, the experiment is planned so that the size of each treatment group provides the greatestsensitivity that the effect on the outcome actually is due to the experimental manipulation in the study.Variables The variables need to be specified in an experiment so that it is clear to readers what groups arereceiving the experimental treatment and what outcomes are being measured. 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). 3.2. Further, because the writing structure of a qualitative project mayvary considerably from study to study, the methods section should also include comments about thenature of the final written product. The dropout rate the previous year was 25%. You can publish your book online for free in a few minutes. Conduct a semistructured interview, audiotape the interview, and transcribe the interview. endobj Organize and prepare the data for analysis. 14 0 obj 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. Start coding all of the data. Newark, DE: International Reading Association. Inthe health sciences, a popular approach is to use predetermined codes based on the theory beingexamined. (2009). 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. 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 three counseling conditions, nonsexist-humanistic, liberal, and radical feminist, were depicted by 10 min videotape vignettes of a second counseling session between a female counselor and a female client. What would a visual model of this design look like?_____________ What instrument(s) will be used to measure the outcome in the study? Daniel. The number of the selected population will be number of students ranging on 17-18 years old. This book was written by John W. Creswell and published by Sage in . Alsowritten on this form might be demographic information about the time, place, and date of the fieldsetting where the observation takes place. (2017) Research Design: Qualitative, Quantitative, and Mixed Methods Approaches. As with any softwareprogram, qualitative software programs require time and skill to learn and employ effectively,although books for learning the programs are widely available. Thisplan might involve handouts, lessons, and special written instructions to help students in thisexperimental group learn how to study a subject using computers. Furthermore, its focus on theory and paradigms is done in a way that helps . 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. These lessons could be the researchers personal interpretation, couched inthe understanding that the inquirer brings to the study from a personal culture, history, andexperiences. (Several of these tests are mentioned in Table 8.3,which was presented earlier.) Quantitative is based on testing a theory, measured with numbers, Methodologists have written excellent discussions about the underlying logic ofsampling theory (e.g., Babbie, 2007; Fowler, 2009). endobj Collect sounds (e.g., musical sounds, a childs laughter, car horns honking). 2.
