Descriptive research, according to Best Kahn (2006), uses quantitative methods to describe what is, describing, recording, analyzing and interpreting conditions that exist. 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). This includes limiting the number of results, excluding resources and only using specific research procedures to gather data to reach a particular objective. Thecollection procedures in qualitative research involve four basic types and their strengths andlimitations, as shown in Table 9.2. A final step in data analysis involves making an interpretation in qualitative research ofthe findings or results. Learn more. These designs focus on datacollection, analysis, and writing, but they originate out of disciplines and flow throughout the processof research (e.g., types of problems, ethical issues of importance). [pp. Potential threats to external validity also must be identified and designs created to minimize thesethreats. 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. 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. posttest, thus impacting the scores on the outcome. Moreover, Creswell (1994) has given a very concise definition of quantitative research as a type of research that is `explaining phenomena by collecting numerical data that are analyzed using mathematically based methods (in particular statistics).' Let's study this definition step by step. Review the checklist in Table 8.1 after you write the section to determine if all components have been addressed. Comment about sensitive ethical issues that may arise (see Chapter 3). Discuss steps taken to gain entry to the setting and to secure permissions to study the participantsor situation (Marshall & Rossman, 2011). It furtherexpands on the data analysis steps and the methods used for presenting the data, interpreting it,validating it, and indicating the potential outcomes of the study. They do not bring individuals into a lab (a contrived situation), nor do they typically send out instruments for individuals to complete. Qualitative Inquiry and Research Design: Choosing Among Five Approaches. endobj Provide a reference to this purpose from one of the survey method texts (several areidentified in this chapter). On what basis was this size chosen?_____________ What will be the procedure for sampling these individuals (e.g., random, nonrandom)?_____________ What instrument will be used in the survey? 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. Methodologists have written excellent discussions about the underlying logic ofsampling theory (e.g., Babbie, 2007; Fowler, 2009). Table 9.1presents a checklist for reviewing the qualitative methods section of your proposal to determinewhether you have addressed important topics.Table 9.1 A Checklist of Questions for Designing a Qualitative Procedure_____________ Are the basic characteristics of qualitative studies mentioned?_____________ Is the specific type of qualitative design to be used in the study mentioned? Identify the type of experimental design to be used in the proposed study. Will the study be disruptive?How will the results be reported? Also mention the type of scalesused to measure the items on the instrument, such as continuous scales (e.g., strongly agree tostrongly disagree) and categorical scales (e.g., yes/no, rank from highest to lowest importance). <>18]/P 32 0 R/Pg 405 0 R/S/Link>> Conduct chart audits. This process, too, is different from quantitative research in which researchers go to greatlengths to preserve all of the data and reconstruct or replace missing data. A confidence interval of 95%, for example, indicates that 95out of 100 times the observed score will fall in the range of values. It also involvesdiscussing the sample for the study and the overall data collection and recording procedures. 3536; Authors described the procedure used in the experiment. Finally,less desirable is a nonprobability sample (or convenience sample), in which respondents are chosenbased on their convenience and availability. All information used in this analysis was derived fromquestionnaire data. Instead, he recommended that sample sizedetermination relates to the analysis plan for a study. Three counseling scripts were initially developed on the basis of distinctions between nonsexist-humanistic, liberal, and radical feminist philosophies and attendant counseling implications. personal biases and a flexible structure.

Thisoften leads to compromises in the researchers ability to disclose information and raises issues of animbalance of power between the inquirers and the participants. 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). Randomly assign one member of each pair to the experimental group and the other member to the control group. Read or look at all the data. One group, for example,may participate in a special computer-assisted learning plan used by a teacher in a classroom. 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. AUTHORS: Timothy Adu Gyamfi, Edward Nana-Addy, Wiliam Gyadu . Step 3. Alex. Gibbs et al (20 07) and Patton (2002) demonstrated that there were a number of methods the research ers would . 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. Asking, What were the lessons learned? captures the essence of this idea(Lincoln & Guba, 1985). There are several ways that you can sample. Insome survey projects, the researcher assembles an instrument from components of severalinstruments. 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?) Single-subject experimental research: Applications for literacy. 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. The statistical significance testing reports anassessment as to whether the observed scores reflect a pattern other than chance. 2021-03-30T12:20:34-07:00 This is a sampling frame (to be discussed later). Also determine whether there was consistency in test administrationand scoring (Were errors caused by carelessness in administration or scoring? 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. Thus, qualitative software programs havebecome quite popular, and they help researchers organize, sort, and search for information in text orimage databases (see Guest and colleagues [2012] chapter on qualitative data analysis software).Several excellent computer software programs are available, and they have similar features: goodtutorials and demonstration files, the ability to incorporate both text and image (e.g., photographs)data, the features of storing and organizing data, the search capacity of locating all text associatedwith specific codes, interrelated codes for making queries of the relationship among codes, and theimport and export of qualitative data to quantitative programs, such as spreadsheets or data analysisprograms. A qualitative observation is when the researcher takes field notes on the behavior and activities of individuals at the research site. This is certainlyone approach to the sample size issue. Cluster sampling is ideal when it is impossible or impractical to compile a list of theelements composing the population (Babbie, 2007). Perhaps draw lines between your categories to show interrelationships. <>35]/P 23 0 R/Pg 389 0 R/S/Link>> Many qualitative researchers also usevisuals, figures, or tables as adjuncts to the discussions.

Threats to construct validityoccur when investigators use inadequate definitions and measures of variables.Table 8.6 Types of Threats to External ValidityTypes of Description of Threat In Response, Actions the Researcher Can TakeThreats toExte rnal The researcher restricts claims about groups to which theValidity results cannot be generalized. Guiding Question. Mark. endobj Another approach is equally viable. ]Data were collected by means of a questionnaire containing 116 items. 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. <>63 0 R]/P 69 0 R/S/Link>> In addition,instruments are being increasingly designed through online surveys products (see Sue & Ritter, 2012,for a discussion of products such as Survey Monkey and Zoomerang and important criteria toconsider when choosing software and a survey host). Use the coding process to generate a description of the setting or people as well ascategories or themes for analysis. 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. The median for the first half of the sample was then used to categorize the second half of the group as feminist or nonfeminist, and the remainder of the participants was randomly assigned to conditions separately from each feminist orientation group to ensure nearly equal cell sizes.

In this approach, the researcher chooses a random start on a list and selects every Xnumbered people on the list. Cluster together similar topics. 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). 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. This widely usedbehavioral research design explores the effects of each treatment separately and also the effects ofvariables used in combination, thereby providing a rich and revealing multidimensional view.
