Research design refers to the overall strategy utilized to carry out research  that defines a succinct and logical plan to tackle established research question s through the collection, interpretation, analysis, and discussion of data. The methodologies and methods incorporated in the design of a research study will depend on the standpoint of the researcher over their beliefs in the nature of knowledge see epistemology and reality see ontology , often shaped by the disciplinary areas the researcher belongs to. The design of a study defines the study type descriptive, correlational, semi-experimental, experimental, review, meta-analytic and sub-type e. There are many ways to classify research designs.
Research Methods Guide: Research Design & Method
Before beginning your paper, you need to decide how you plan to design the study. The research design refers to the overall strategy that you choose to integrate the different components of the study in a coherent and logical way, thereby, ensuring you will effectively address the research problem; it constitutes the blueprint for the collection, measurement, and analysis of data. Note that the research problem determines the type of design you should use, not the other way around!
De Vaus, D. Research Design in Social Research. Research Methods Knowledge Base. The function of a research design is to ensure that the evidence obtained enables you to effectively address the research problem logically and as unambiguously as possible.
In social sciences research, obtaining information relevant to the research problem generally entails specifying the type of evidence needed to test a theory, to evaluate a program, or to accurately describe and assess meaning related to an observable phenomenon.
With this in mind, a common mistake made by researchers is that they begin their investigations far too early, before they have thought critically about what information is required to address the research problem.
Without attending to these design issues beforehand, the overall research problem will not be adequately addressed and any conclusions drawn will run the risk of being weak and unconvincing. As a consequence, the overall validity of the study will be undermined. The length and complexity of describing research designs in your paper can vary considerably, but any well-developed description will achieve the following :.
The research design is usually incorporated into the introduction. You can get an overall sense of what to do by reviewing the literature of studies that have utilized the same research design. The Research Methods Online database contains links to more than , pages of SAGE publisher's book, journal, and reference content on quantitative, qualitative, and mixed research methodologies. Also included is a collection of case studies of social research projects that can be used to help you better understand abstract or complex methodological concepts.
The Research Methods Videos database contains hours of tutorials, interviews, video case studies, and mini-documentaries covering the entire research process. Creswell, John W. David Creswell.

New York: Guilford, Definition and Purpose. The essentials of action research design follow a characteristic cycle whereby initially an exploratory stance is adopted, where an understanding of a problem is developed and plans are made for some form of interventionary strategy.
Then the intervention is carried out [the "action" in action research] during which time, pertinent observations are collected in various forms. The new interventional strategies are carried out, and this cyclic process repeats, continuing until a sufficient understanding of [or a valid implementation solution for] the problem is achieved. The protocol is iterative or cyclical in nature and is intended to foster deeper understanding of a given situation, starting with conceptualizing and particularizing the problem and moving through several interventions and evaluations.

A case study is an in-depth study of a particular research problem rather than a sweeping statistical survey or comprehensive comparative inquiry.
It is often used to narrow down a very broad field of research into one or a few easily researchable examples. The case study research design is also useful for testing whether a specific theory and model actually applies to phenomena in the real world.
It is a useful design when not much is known about an issue or phenomenon. Case Studies. Writing CSU. Encyclopedia of Case Study Research.

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. Conditions necessary for determining causality:.

Often used in the medical sciences, but also found in the applied social sciences, a cohort study generally refers to a study conducted over a period of time involving members of a population which the subject or representative member comes from, and who are united by some commonality or similarity.
Using a quantitative framework, a cohort study makes note of statistical occurrence within a specialized subgroup, united by same or similar characteristics that are relevant to the research problem being investigated, r ather than studying statistical occurrence within the general population. Using a qualitative framework, cohort studies generally gather data using methods of observation.
Cohorts can be either "open" or "closed. Healy P, Devane D. Cohort Analysis. Evidence-Based Dentistry 7 : 51—52; Payne, Geoff. Victor Jupp, editor. Himmelfarb Health Sciences Library.
Cross-sectional research designs have three distinctive features: no time dimension; a reliance on existing differences rather than change following intervention; and, groups are selected based on existing differences rather than random allocation. 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.
As such, researchers using this design can only employ a relatively passive approach to making causal inferences based on findings. Bethlehem, Jelke. London, England: Sage, , pp. Michael S. Thousand Oaks, CA: , pp. Paul J. Lavrakas, ed. Healthknowledge, Cross-Sectional Study. Descriptive research designs help provide answers to the questions of who, what, when, where, and how associated with a particular research problem; a descriptive study cannot conclusively ascertain answers to why.
Descriptive research is used to obtain information concerning the current status of the phenomena and to describe "what exists" with respect to variables or conditions in a situation. Anastas, Jeane W. Chapter 5, Flexible Methods: Descriptive Research.
Salkind and Kristin Rasmussen, editors. Descriptive Research Methodologies. Powerpoint Presentation; Shuttleworth, Martyn. Descriptive Research Design , September 26, A blueprint of the procedure that enables the researcher to maintain control over all factors that may affect the result of an experiment.
In doing this, the researcher attempts to determine or predict what may occur. Experimental research is often used where there is time priority in a causal relationship cause precedes effect , there is consistency in a causal relationship a cause will always lead to the same effect , and the magnitude of the correlation is great. The classic experimental design specifies an experimental group and a control group.
The independent variable is administered to the experimental group and not to the control group, and both groups are measured on the same dependent variable.
Subsequent experimental designs have used more groups and more measurements over longer periods. True experiments must have control, randomization, and manipulation. Chapter 7, Flexible Methods: Experimental Research. Nicholas Walliman, editor. London, England: Sage, , pp, ; Experimental Research.

Research design is the framework of research methods and techniques chosen by a researcher. The design allows researchers to hone in on research methods that are suitable for the subject matter and set up their studies up for success. There are three main types of research design: Data collection, measurement, and analysis. The type of research problem an organization is facing will determine the research design and not vice-versa. The design phase of a study determines which tools to use and how they are used. An impactful research design usually creates a minimum bias in data and increases trust in the accuracy of collected data.
Generally, research framework can be defined as a guideline or structure mapping for the researcher that derived from the research objectives or.

Вот хочу попробовать сделать кое-какую перенастройку да проверить электронную почту, - сказал Хейл. Он смотрел на нее с нескрываемым любопытством. - Что ты сказала. Чем ты занята. - Я ничего не говорила, - ответила Сьюзан. Хейл удивленно поднял брови.
Явный звук шагов на верхней площадке. Хейл в ужасе тотчас понял свою ошибку. Стратмор находится на верхней площадке, у меня за спиной. Отчаянным движением он развернул Сьюзан так, чтобы она оказалась выше его, и начал спускаться.
Мы можем восстановить его репутацию. Мы должны пойти на. - Слишком поздно, - сказал Стратмор.
