Which among the following are related to the quality of research articles?
(A) number of research articles
(B) impact factor
(C) citation index
(D) frequency of their publication
(E) h-index
Choose the correct answer from the options given below:

Correct option is C

The quality of research articles is typically evaluated using the following metrics:
· Impact Factor (B): Measures the average number of citations to articles published in a specific journal. Higher impact factors suggest that the journal's articles are frequently cited, indicating high quality.
· Citation Index (C): Tracks how many times an article has been cited in other research, reflecting its influence and relevance in the academic community.
· h-index (E): Combines the number of publications and their citations to measure both the productivity and impact of a researcher or journal. A high h-index indicates significant contributions to the field.
The number of research articles (A) and the frequency of their publication (D) are not directly related to the quality of the research but rather to quantity and regularity.
Information Booster: 1. Impact factor is commonly used to assess journals, reflecting their influence based on citation frequency.
2. Citation index measures the impact of individual research articles based on how often they are referenced by other scholars.
3. h-index evaluates both the productivity and the citation impact of a scholar or research group.
4. The number of research articles published does not necessarily indicate quality but can reflect productivity.
5. The frequency of publication pertains to how often a journal issues new articles but is not a measure of article quality.
