Facione (2011) states that critical thinking includes cognitive skills which build up the very core of critical thinking. These cognitive skills are interpretation, self-regulation, explanation, evaluation, analysis, and inference.

1-5-3 Analysis
“It is to identify the intended and actual inferential relationships among statements, questions, concepts, descriptions, or other form of representation intended to express belief, judgment, experiences, reasons, information, or opinions” (Facione, 2011, p. 5).
Moreover, Rubenfeld and Scheffer (2001) define analysis as searching or breaking a whole into parts to discover their nature, functional and relationships.
1-5-4 Inference
It means, “to identify and secure elements needed to draw reasonable conclusions; to form conjectures and hypothesis; to consider relevant information and to educe the consequences flowing from data, statements, principles, evidence, judgments, beliefs, opinions, concepts, descriptions, questions, or other form of representation” (Facione, 2011, p. 6).
