Pretesting a problem for generalization is helpful because the researcher can check to see if the groups are equivalent. Researchers can also assess mortality effects and determine if the people who withdrew are different from those individuals who finished the study. Pretesting may affect the ability to generalize results because the results can not be generalized to people who were not given a pretest, and pretests are rarely conducted in day-to-day living (Cozby, 274).

4. Distinguish between an exact replication and a conceptual replication. What is the value of a conceptual replication?

An exact replication is a researcher's attempt to exactly duplicate a study's procedures to determine if similar findings can be obtained. A conceptual representation tries to replicate the findings of a research study by manipulating the...

A conceptual replication is valuable because the researcher can determine whether or not the results of the study are generalizable by manipulating or measuring the variables differently than they were used in the first study (Cozby, 2009, 277).
5. What is a meta-analysis?

A meta-analysis is a quantitative technique for comparing a large number of studies in an area. The researcher examines the results for many different studies and combines the results of the studies using statistical procedures to compare given findings. A meta-analysis has several advantages over a literature review. First, definitive conclusions can be drawn from the findings. Secondly, relationships between variables can be examined by comparing the different studies. Last, the meta-analysis can offer comparisons between effect…

An exact replication is a researcher's attempt to exactly duplicate a study's procedures to determine if similar findings can be obtained. A conceptual representation tries to replicate the findings of a research study by manipulating the variables in a different way. A conceptual replication is valuable because the researcher can determine whether or not the results of the study are generalizable by manipulating or measuring the variables differently than they were used in the first study (Cozby, 2009, 277).

A meta-analysis has several advantages over a literature review. First, definitive conclusions can be drawn from the findings. Secondly, relationships between variables can be examined by comparing the different studies. Last, the meta-analysis can offer comparisons between effect sizes (Cozby, 2009, p. 278-279).

population identified and described? Are eligibility criteria specified? Are the sample selection procedures clearly delineated? Yes. The sample consisted of 350 college students at a Midwestern University. All the students were enrolled in a personal health class as a social science elective. Do the sample and population specifications support an inference of construct validity with regard to the population construct? Of n=350, 86% were White, 5% African-American, 4% Asian-American, 3%

generalize to a broad group of individuals (random samples), some designs attempt to determine cause and effect relationships (true experiments), and some used to provide rich, detailed, descriptive, qualitative, and/or quantitative information. The purpose of single-case study is to present or describe a case (or a small number of cases) and not necessarily to represent the large diverse group. Nonetheless single-case studies have been important educational research methodologies (Yin,

generalize how and when research approaches could be blended or adapted for a research study. Blending and adapting the approaches Despite the fact that there is a distinct typology between the five different types of qualitative approaches to research, it is not uncommon to blend these approaches in the real world of investigative study. What is critical to such hybridization is that it is done consciously rather than unconsciously and with

Test Development This research is a mixed methods study designed to explore the perceptions of self-identifying individuals with anxiety and depression regarding any relation between their conditions and their ability to access appropriate healthcare under the Patient Protection and Affordable Care Act. Five respondents completed the questionnaire constructed explicitly for this research study. A review of the literature serves as a canvas of instruments also developed for assessing Axis 1

enhance understanding of a more generalized set of research questions that deal with environments, interactions and relationships. Indeed, qualitative research is often used to form the hypothesis and narrow the question prior to studying the data quantitatively. For example, researchers might use a focus group might be to get an overall "feel" of a response to a product or event. The group makes statements, judgments, remarks, and gives opinion

expression of interest. A topic or subject that, one finds worthy enough of contributing to and that one can contribute to, through academic rigor is forms the body of a research. The work produced thus requires academic training and skills and the outcome is a 'work of scholarship'. The skills that are needed for research are: ability to clearly define a research subject/topic; identify a research query that will
