Effectively describe the data which will be necessary for an adequate testing of the hypotheses and explain how such data will be obtained, and describe the methods of analysis to be applied to the data in determining whether or not the hypotheses are true or false ..

In doing this, the researcher attempts to determine or predict what may occur. The limitation is that the sources must be both authentic and valid. The purpose of a historical research design is to collect, verify, and synthesize evidence from the past to establish facts that defend or refute a hypothesis.
Due to the repetitive nature of this research design, minor changes and adjustments can be done during the initial parts of the study to correct and hone the research method. Difficult to apply ethnographic and other qualitative methods to experimentally designed studies. This design only provides a snapshot of analysis so there is always the possibility that a study could have differing results if another time-frame had been chosen.
Because descriptive designs often utilize observational methods as opposed to quantitative methods, the results cannot be replicated. In the policy arena or applied to practice, exploratory studies help establish research priorities and where resources should be allocated. Because the study is conducted serially, the results of one sample are known before the next sample is taken and analyzed.
Given this, the number of study participants remains constant (or can only decrease). In understood more as an broad approach to examining a research problem than a methodological design, philosophical analysis and argumentation is intended to challenge deeply embedded, often intractable, assumptions underpinning an area of study. For sequential designs where one phase of qualitative research builds on the quantitative phase or vice versa, decisions about what results from the first phase to use in the next phase, the choice of samples and estimating reasonable sample sizes for both phases, and the interpretation of results from both phases can be difficult.
This also increases the chance that key variables change during the course of the study, potentially impacting the validity of the findings. Longitudinal studies facilitate the prediction of future outcomes based upon earlier factors. Causal effect (nomothetic perspective) occurs when variation in one phenomenon, an independent variable, leads to or results, on average, in variation in another phenomenon, the dependent variable.
Can be used to generate new hypotheses or highlight research problems for future studies. This means the researcher can obtain a limitless number of subjects before making a final decision whether to accept the null or alternative hypothesis. The use of cohorts is often mandatory because a randomized control study may be unethical. The cross-sectional design can only measure differences between or from among a variety of people, subjects, or phenomena rather than a process of change. Meta-analysis is an analytical methodology designed to systematically evaluate and summarize the results from a number of individual studies, thereby, increasing the overall sample size and the ability of the researcher to study effects of interest.
Using a quantitative framework, a sequential study generally utilizes sampling techniques to gather data and applying statistical methods to analze the data. Brings clarity to general guiding practices and principles of an individual or group. Depending on the sample size, the process of reviewing and synthesizing multiple studies can be very time consuming. May generate new knowledge new insights or uncover hidden insights, patterns, or relationships that a single methodological approach might not reveal.

True experiments, whilst giving analyzable data, often adversely influence the normal behavior of the subject a. This type of research is used to measure what impact a specific change will have on existing norms and assumptions. It is a useful design when not much is known about an issue or phenomenon. Any group that is knowingly studied is altered to some degree by the presence of the researcher, therefore, potentially skewing any data collected.

This is a collaborative and adaptive research design that lends itself to use in work or community situations. Cross-sectional studies provide a clear snapshot of the outcome and the characteristics associated with it, at a specific point in time. Tashakkori and creswell (2007) and other proponents of mixed methods argue that the design encompasses more than simply combining qualitative and quantitative methods but, rather, reflects a new third way epistemological paradigm that occupies the conceptual space between positivism and interpretivism. The use of cohorts is often mandatory because a randomized control study may be unethical. Measurements are taken on each variable over two or more distinct time periods. For example, with longitudinal surveys, the same group of people is interviewed at regular intervals, enabling researchers to track changes over time and to relate them to variables that might explain why the changes occur. Approach excels at bringing us to an understanding of a complex issue through detailed contextual analysis of a limited number of events or conditions and their relationships. While a philosophical analysis may render problematic that which was once simple or taken-for-granted, the writing can be dense and subject to unnecessary jargon, overstatement, andor excessive quotation and documentation. The sources of historical materials must be archived consistently to ensure access. Appropriate time order -- to conclude that causation was involved, one must see that cases were exposed to variation in the independent variable before variation in the dependent variable.The purpose of this guide is to provide advice on how to develop and organize a research paper in the social sciences.
