It can be more difficult to control extraneous variables than a lab exp.
|
Detailed explanation-1: -Field experiments are done in the everyday (i.e. real life) environment of the participants. The experimenter still manipulates the independent variable, but in a real-life setting (so cannot really control extraneous variables). An example is Holfing’s hospital study on obedience.
Detailed explanation-2: -Field experiments are experiments carried out outside of laboratory settings. They randomly assign subjects (or other sampling units) to either treatment or control groups in order to test claims of causal relationships.
Detailed explanation-3: -Peter Bohm (1935–2005) was the father of modern field experiments. He clearly un-derstood and stated the differences between laboratory experiments and experiments with field counterparts.
Detailed explanation-4: -Field experiments are studies using experimental design that occur in a natural setting. Researchers examine how the manipulation of at least one independent variable leads to a change in a dependent variable in the context of the natural environment.
