When a sociologist conducts an experiment in a natural setting and examines the natural course of social life without intervening,this is called:

A) a field experiment
B) a natural experiment
C) a laboratory experiment
D) a survey experiment
E) a classical experiment

In this scenario, the sociologist is observing social life as it naturally occurs without any manipulation or intervention. This fits the definition of a natural experiment. A field experiment involves manipulating variables in a natural setting, while a laboratory experiment involves manipulating variables in a controlled environment. A survey experiment involves collecting data through surveys and questionnaires. A classical experiment involves random assignment to treatment and control groups.
