Quartiles
In addition to the IF, rankings of journals in each subject category are divided into quartiles, which rank the journals from highest to lowest based on their IF. There are four quartiles: Q1, Q2, Q3 and Q4, which are explained below.
Definition of quartile ranking of DDI publications
| Quartile | Definition |
| Quartile 1 (Q1) | Denotes the top 25% of the IF distribution |
| Quartile 2 (Q2) | Denotes middle-high position distribution (top 50% to top 25%) |
| Quartile 3 (Q3) | Denotes middle-low position distribution (top 75% to top 50%) |
| Quartile 4 (Q4) | Denotes lowest position (bottom 25% of the IF distribution) |
