What is qualitative research? We define qualitative research as an iterative process in which improved understanding to the scientific community is achieved by making new significant distinctions resulting from getting closer to the phenomenon studied.

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 your research problem determines the type of design you can use, not the other way around!

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 as unambiguously as possible. In social sciences research, obtaining evidence 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 a phenomenon. However, researchers can often begin their investigations far too early, before they have thought critically about about what information is required to answer the study's research questions.

Without attending to these design issues beforehand, the conclusions drawn risk being weak and unconvincing and, consequently, will fail to adequate address the overall research problem. Given this, the length and complexity of research designs can vary considerably, but any sound design will do the following things:. New Yortk University, Spring 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 the cyclic process repeats, continuing until a sufficient understanding of or implement able 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. Gall, Meredith. Educational Research: An Introduction. Chapter 18, Action Research.

Norman Denzin and Yvonna S. Locoln, eds. A case study is an in-depth study of a particular research problem rather than a sweeping statistical survey. 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 a phenomenon. Anastas, Jeane W. The Art of Case Study Research. Case Study Research: Design and Theory. Applied Social Research Methods Series, no. Most social scientists seek causal explanations that reflect tests of hypotheses. 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:. Bachman, Ronet. Chapter 5, Causation and Research Designs. Chapter 11, Nonexperimental Research: Correlational Designs. 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. Evidence-Based Dentistry 7 : 51—52; Study Design 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 diffrerences between or from among a variety of people, subjects, or phenomena rather than change. As such, researchers using this design can only employ a relative passive approach to making causal inferences based on findings.

Hall, John. Paul J. Lavrakas, ed. Thousand Oaks, CA: Sage, , pp. 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.

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.

Research Methods by Dummies. Department of Psychology. Experimental Design. Experimental Research. Slideshare presentation. An exploratory design is conducted about a research problem when there are few or no earlier studies to refer to. The focus is on gaining insights and familiarity for later investigation or undertaken when problems are in a preliminary stage of investigation. The goals of exploratory research are intended to produce the following possible insights:.

Cuthill, Michael. Catalano, and D. The purpose of a historical research design is to collect, verify, and synthesize evidence from the past to establish facts that defend or refute your hypothesis. It uses secondary sources and a variety of primary documentary evidence, such as, logs, diaries, official records, reports, archives, and non-textual information [maps, pictures, audio and visual recordings].

The limitation is that the sources must be both authentic and valid. Savitt, Ronald. Chapter 16, Historical Research. A longitudinal study follows the same sample over time and makes repeated observations. With longitudinal surveys, for example, 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.

Longitudinal research designs describe patterns of change and help establish the direction and magnitude of causal relationships. Measurements are taken on each variable over two or more distinct time periods.

This allows the researcher to measure change in variables over time. It is a type of observational study and is sometimes referred to as a panel study. This type of research design draws a conclusion by comparing subjects against a control group, in cases where the researcher has no control over the experiment. There are two general types of observational designs.

In direct observations, people know that you are watching them. Unobtrusive measures involve any method for studying behavior where individuals do not know they are being observed. An observational study allows a useful insight into a phenomenon and avoids the ethical and practical difficulties of setting up a large and cumbersome research project.

Research Design: Meaning and Importance

The purposes and criteria for formulating a design of research, conditions for judging causality, and use of research design as a control of variance are discussed. The purpose of a research design is to provide a plan of study that permits accurate assessment of cause and effect relationships between independent and dependent variables. The classic controlled experiment is an ideal example of good research design. Factors that jeopardize the evaluation of the effect of experimental treatment internal validity and the generalizations derived from it external validity are identified. Sources of variance can be controlled by eliminating a variable, randomization, matching, or including a variable as part of the design. A research project should be so designed that 1 it answers the questions being investigated, 2 extraneous factors are controlled, and 3 the degree of generalization that can be made is valid. Abstract The purposes and criteria for formulating a design of research, conditions for judging causality, and use of research design as a control of variance are discussed.

Research design refers to the overall strategy utilized to carry out research [1] 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. Nonetheless, the list below offers a number of useful distinctions between possible research designs. A research design is an arrangement of conditions or collection.

Nonetheless, the list below offers a number of useful distinctions between possible research designs.

Descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodologies, but instead it can utilize elements of both, often within the same study. The term descriptive research refers to the type of research question, design, and data analysis that will be applied to a given topic. Descriptive statistics tell what is, while inferential statistics try to determine cause and effect. The type of question asked by the researcher will ultimately determine the type of approach necessary to complete an accurate assessment of the topic at hand.

A research design is a framework or blueprint for conducting the marketing research project. It details the procedures necessary for obtaining the information needed to structure or solve marketing research problems. In simple words it is the general plan of how you will go about your research.

How to create a research design

Step 1: Consider your priorities and practicalities

Published on June 13, by Shona McCombes. Revised on March 19, The research design is a framework for planning your research and answering your research questions. Creating a research design means making decisions about:. The research design sets the parameters of your project: it determines exactly what will and will not be included. It also defines the criteria by which you will evaluate your results and draw your conclusions.
