Summary
Bibliometric analysis reveals citation rates vary widely across scientific fields. Factors like article count, recent references, and funding agencies influence impact, with a few journals dominating highly cited research.
Area of Science:
- Covers 236 scientific categories, analyzing bibliometric data and citation rates.
- Highlights significant variations in citation impact across diverse research fields.
Background:
- Scientific databases track research literature, providing metrics like citations and author counts.
- Current methods offer limited quantitative comparisons of researcher impact across different scientific categories.
Purpose of the Study:
- To compile bibliometric indicators for 236 science categories.
- To analyze citation rates of the 500 most cited articles within each category.
- To identify factors influencing scientific impact and publication trends.
Main Methods:
- Compiled bibliometric indicators for 236 science categories.
- Analyzed citation rates of the top 500 cited articles per category.
- Employed regression modeling to assess relationships between citation rates and category characteristics.
- Examined the role of journals in publishing highly cited research.
Main Results:
- Citation rates vary by several orders of magnitude, highest in multidisciplinary sciences, general internal medicine, and biochemistry; lowest in literature, poetry, and dance.
- Top article citation rates correlate positively with the square root of the number of articles in a category and negatively with reference age.
- Citation rates increase with the number of funding agencies supporting the research.
- A few journals dominate the publication of highly cited articles, with four journals publishing 60% of the top 500 cited articles in each category.
Conclusions:
- Scientific impact, measured by citation rates, is highly field-dependent.
- Category size, citation of recent research, and diverse funding sources positively influence impact.
- Highly cited research is concentrated in a small number of prominent journals, indicating a significant publication bias.

01:11How Data are Classified: Categorical Data
46.8K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

02:40The Scientific Method
66.3K
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

03:50The Scientific Method
69.9K
Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.

The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

01:11Statistical Analysis: Overview
16.7K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
