It shows the rankings of the journal within its own group and it is a useful guide for researchers in the selection of the journal, however it should be used with caution in academic career advancement. Quartile scores may vary according to the scientific categories. The Q scores of a journal briefly show the 25% quantile resulting from quartered the number of journals in the area where the journal is placed. The first quartile has the top 25% of the journals and gets the Q1 score and the last quartile gets Q4 score. And so, the second 25% slice takes Q2 score and the third 25% slice takes Q3 score.

Derginin kendi grubu içindeki sıralamasını gösterir, yararlıdır ve akademisyenlerin dergi seçiminde de yol göstericidir ancak akademik yükseltmelerde kullanılmasında dikkatli olunmalıdır. Q değerleri bilimsel alanlara göre değişiklik gösterebilir. Bir derginin Q değeri kısaca, derginin bulunduğu alandaki dergi sayısının dörde bölünmesiyle ortaya çıkan% 25’lik dilimleri gösterir. İlk% 25’lik dilim Q1 değerini alırken, son% 25’lik dilim Q4 değerini alır. Dolayısıyle ikinci% 25’lik dilim Q2, üçüncü% 25’lik dilim ise Q3 değerini alır. CR - 1. Garfield E.
