longitudinal study Part of the Customer data management glossary: A longitudinal study is an observational research method in which data is gathered for the same subjects repeatedly over a period of time. Longitudinal research projects can extend over years or even decades. In a longitudinal cohort study, the same individuals are observed over the study period. Cohort studies are common in medicine, psychology and sociology, where they allow researchers to study changes over time.

Quantitative Research Design Quantitative research design is an excellent way of finalizing results and proving or disproving a hypothesis. The structure has not changed for centuries, so is standard across many scientific fields and disciplines.

Introduction to Sociology/Print version Longitudinal study. A longitudinal study (or longitudinal survey, or panel study) is a quasi-experimental research design that involves repeated observations of the same variables (e.g., people) over long periods of time, often many decades (i.e., uses longitudinal data).

Experimental Design Experimental designs are often touted as the most rigorous of all research designs or, as the gold standard against which all other designs are judged. In one sense, they probably are. If you can implement an experimental design well (and that is a big if indeed), then the experiment is probably the strongest design with respect to internal validity. Why? Recall that internal validity is at the center of all causal or cause-effect inferences.

Definition of Research Design Definition of Research Design. The formidable problem which follows the work of defining the research problem is the preparing of the design of the research project, typically referred to as the “research design”. Research design can be defined as a conceptual structure within which research will likely be done. It comprises the blueprint for the collection, measurement and analysis of data. Decisions regarding what, where, when, how much, by what means with regards to an enquiry or a research design are taken.

Understanding Research Study Designs A double blind study is the most rigorous clinical research design because, in addition to the randomization of subjects, which reduces the risk of bias, it can eliminate or minimize the placebo effect which is a further challenge to the validity of a study.

Descriptive Study A descriptive study design is one in which your primary goal is to assess a sample at one specific point in time without trying to make inferences or causal statements. In general, there are three primary reasons to conduct descriptive studies: To identify areas for further research.

A clear understanding of the conclusions that might be drawn at the end of the study is also important at this stage.

Research Design: Defined and Explained Definition of Research Design. The term “research design” can be defined as, The systematic study plan used to turn a research question or research questions into a “testing project” or “experimental study”. OR. A research design is a set of advance decisions that make up the master plan specifying the methods and procedures for collecting and analyzing the needed information. A research design is based on the research questions and can be considered as a blueprint for research, addressing at least four of the problems:

- 4 Time Dimension Cross-sectional Research One-shot or cross-sectional studies are those in which data is gathered once, during a period of days, weeks or months. Many cross-sectional studies are exploratory or descriptive in purpose. They are designed to look at how things are now, without any sense of whether there is a history or trend at work. Longitudinal Research Research carried out longitudinally involves data collection at multiple points in time.

Chapter 7. Longitudinal studies 7. In a longitudinal study subjects are followed over time with continuous or repeated monitoring of risk factors or health outcomes, or both. Such investigations vary enormously in their size and complexity. At one extreme a large population may be studied over decades.
