___________ is the process of developing one's analytical ability using principles, concepts, and values.

The process of developing one's analytical ability using principles, concepts, and values is best described by education. Education encompasses a structured approach to learning that not only imparts knowledge but also enhances critical thinking and analytical skills. Through education, individuals are taught frameworks and methodologies that help them interpret information, evaluate arguments, and make informed decisions based on evidence and ethical considerations.

While training focuses primarily on acquiring specific skills or competencies, it may not delve deeply into the theoretical foundations or broad concepts necessary for comprehensive analytical development. Understanding refers to the grasp of knowledge but does not inherently signify the process of learning as a whole. Wisdom, often associated with the application of knowledge and experiences, represents a more advanced state of thought that comes from education but is not itself the process of acquiring those foundational analytical capabilities. Therefore, education is the most fitting term for the process described in the question.
