Understanding the Quartiles of the Journals
The journal's quartiles assist us in determining the journal's reliability and quality. It's based on the Scimago Journal Ranking (SJR), which isn't the same as the impact factor.
SJR was developed by a research group in the 2000s using Scopus data. Unlike Impact Factor, SJR publishes open access and covers a wider spectrum of publications. SJR Scopus considers the overall number of citations as well as the weight of each reference. As a result, SJR is utilized to determine the journal's quartile.
A high quartile in Scopus means that the journal sets research trends, and its authors are experts in their field.
If a journal is in the Q2 range, it does not imply that all research papers from all fields will be given Q2 credibility. It will only apply to selected specializations dependent on the scope of the journal.
Quartiles are bands of serial titles that have been grouped together because they occupy a similar position within their subject categories.
The quartiles are:
Quartile 1: serial titles in 99-75th percentiles
Quartile 2: serial titles in 74-50th percentiles
Quartile 3: serial titles in 49-25th percentiles
Quartile 4: serial titles in 24-0 percentiles
