what does research comparative study mean

A comparative study is a kind of method that analyzes phenomena and then put them together. to find the points of differentiation and similarity (MokhtarianPour, 2016). A comparative perspective ...

Definition. Comparative research, simply put, is the act of comparing two or more things with a view to discovering something about one or all of the things being compared. This technique often utilizes multiple disciplines in one study. When it comes to method, the majority agreement is that there is no methodology peculiar to comparative ...

Comparative is a concept that derives from the verb "to compare" (the etymology is Latin comparare, derivation of par = equal, with prefix com-, it is a systematic comparison).Comparative studies are investigations to analyze and evaluate, with quantitative and qualitative methods, a phenomenon and/or facts among different areas, subjects, and/or objects to detect similarities and/or ...

Research designed to look at events from the present into the future, such as a study looking at the development of symptoms in individuals exposed to a pollutant, is referred to as prospective research. Comparative science was significantly strengthened in the late 19th and early 20th century with the introduction of modern statistical methods.

What makes a study comparative is not the particular techniques employed but the theoretical orientation and the sources of data. All the tools of the social scientist, including historical analysis, fieldwork, surveys, and aggregate data analysis, can be used to achieve the goals of comparative research.

Comparative research in communication and media studies is conventionally understood as the contrast among different macro-level units, such as world regions, countries, sub-national regions, social milieus, language areas and cultural thickenings, at one point or more points in time.

Definition. The goal of comparative analysis is to search for similarity and variance among units of analysis. Comparative research commonly involves the description and explanation of similarities and differences of conditions or outcomes among large-scale social units, usually regions, nations, societies, and cultures.

In eHealth evaluation, comparative studies aim to find out whether group differences in eHealth system adoption make a difference in important outcomes. These groups may differ in their composition, the type of system in use, and the setting where they work over a given time duration. The comparisons are to determine whether significant differences exist for some predefined measures between ...

A Comparative Study involves analyzing the dynamics of societies across different scales and environmental conditions to understand their emergence and functioning. The aim is to identify a common level of abstraction for describing and comparing these dynamics systematically. AI generated definition based on: Current Opinion in Environmental ...

Definition. Within higher education, the catch-all term "comparative research" typically denotes inter- or cross-national or inter- or cross-cultural comparative research. For an overall terminology, this type of research is defined here as empirical research that collects data and/or carries out observations across national, geographical ...

2.1 Introduction. In this chapter we shall elaborate on the essentials of the 'art of comparing' by discussing. relation between theory and method as it is discussed with reference to the Comparative. approach. In order to clarify this point of view, we shall first discuss some of the existing.

COMPARATIVE RESEARCH Types of Comparative Research There are several methods of doing comparative analysis and Tilly (1984) distinguishes four types of comparative analysis namely: individualizing, universalizing, variation-finding and encompassing (p.82). Adding to the types of comparative

Research goals. Comparative communication research is a combination of substance (specific objects of investigation studied in diferent macro-level contexts) and method (identification of diferences and similarities following established rules and using equivalent concepts).

under investigation across time, such as in a longitudinal study of the same students over time. A third category of comparative study involved a comparison to some form of externally normed results, such as populations taking state, national, or international tests or prior research assessment from a published study or studies.

A Primer on Effectiveness Research. The Institute of Medicine, the independent nonprofit organization that is a part of the National Academy of Sciences, defines "comparative effectiveness research" as "the generation and synthesis of evidence that compares the benefits and harms of alternative methods to prevent, diagnose, treat, and monitor a clinical condition or improve the delivery ...

Causal-comparative research is a methodology used to identify cause-effect relationships between independent and dependent variables. Researchers can study cause and effect in retrospect. This can help determine the consequences or causes of differences already existing among or between different groups of people.

But international comparative research that collects data or carries out observations across national, geographical, and cultural boundaries and systematically relates such data in comparative analysis is more challenging than non-comparative research for reasons that go beyond issues of data collection: Observing and comparing similarities and ...

One promising research heuristic that attends to different logics of comparison while avoiding these dangers is the comparative case study (CCS) approach. CCS entails three axes of comparison. The horizontal axis encourages comparison of how similar policies and practices unfold across sites at roughly the same level or scale, for example ...

The study design used to answer a particular research question depends on the nature of the question and the availability of resources. In this article, which is the first part of a series on "study designs," we provide an overview of research study designs and their classification. The subsequent articles will focus on individual designs.

Comparative analysis is a method that is widely used in social science. It is a method of comparing two or more items with an idea of uncovering and discovering new ideas about them. It often compares and contrasts social structures and processes around the world to grasp general patterns. Comparative analysis tries to understand the study and ...

Comparative Effectiveness Research (CER) is the generation and synthesis of evidence that compares the benefits and harms of alternative methods to prevent, diagnose, treat and monitor a clinical condition, or to improve the delivery of care. ... Evidence is generated through research that uses various study designs (e.g., observational ...

A comparative study is an adequate research methodology to determine and quantify the relationships between two or more variables, observing different groups that, by choice or circumstance, are ...

Abstract. Comparative effectiveness research (CER) seeks to assist consumers, clinicians, purchasers, and policy makers to make informed decisions to improve health care at both the individual and population levels. CER includes evidence generation and evidence synthesis. Randomized controlled trials are central to CER because of the lack of ...

Background While the motivations of individuals without impairments for participating in mass running events are well-documented, there is a lack of current research exploring why people with physical disabilities engage in these events. This study aims to identify the motives for participation among people with physical disabilities, taking into account factors such as sex, age (emerging ...

The study also represents the launch of the Maternal Brain Project, an international effort supported by the Ann S. Bowers Women's Brain Health Initiative and the Chan Zuckerberg Initiative, for ...
