What is the difference between a lab experiment and a field experiment?

A lab experiment is conducted in a controlled environment where researchers manipulate variables and observe the effects, allowing for high internal validity and control over extraneous factors. In contrast, a field experiment takes place in a natural setting, where researchers manipulate variables in real-world conditions, which enhances external validity but may introduce more uncontrolled variables. While lab experiments prioritize control and precision, field experiments emphasize ecological validity and the relevance of findings to real-life situations.
