How do you find Q1 Q2 Q3 Q4 journals
The process of calculating the quartile ranking involves dividing all the journals in a particular category or field into four groups based on their citation impact factor. The top 25% of journals are classified as Q1 journals, the next 25% as Q2, the next 25% as Q3, and the bottom 25% as Q4.
How do you know if an article is Q1 or Q2
Q1 is occupied by the top 25% of journals in the list; Q2 is occupied by journals in the 25 to 50% group; Q3 is occupied by journals in the 50 to 75% group and Q4 is occupied by journals in the 75 to 100% group. The most prestigious journals within a subject area are those which occupy the first quartile, Q1.
Where can I find my 5-year impact factor
You can use the Journal Citation Reports (JCR) (Clarivate Analytics) or Scimago (Scopus) to check the 5-year impact factor, tier, and ranking by subject of a journal.
