Which of Piaget's stages is characterized by deductive logic, mental trial-and-error, and hypothesis testing?

A) Preoperational
B) Concrete operational
C) Formal operational
D) Advanced adult operational

Deductive Logic

A method of reasoning from one or more statements (premises) to reach a logically certain conclusion, based on the principle that if the premises are true, the conclusion must be true.

Formal Operational

This refers to the final stage in Piaget's theory of cognitive development, where individuals (typically adolescents and adults) gain the ability to think abstractly, logically, and systematically.

Hypothesis Testing

A statistical method that is used to determine whether there is enough evidence in a sample of data to infer that a certain condition is true for the entire population.
