**Introduction to Ravens matrices:**

**Ravens Progressive Matrices** (often referred to simply as **Raven's Matrices**) are multiple choice tests of abstract reasoning, originally developed by Dr John C. Raven in 1936. In each test item, a candidate is asked to identify the missing segment required to complete a larger pattern. Many items are presented in the form of a 3x3 or 2x2 matrix, giving the test its name.(Source : WIKIPEDIA)
