Compare and contrast one laboratory and one field experiment.

A laboratory experiment is where research is done in a highly controlled environment, where the level of control is very important. It is also to examine the validity of the hypotheses.

Out of 22 nurses 21 of them were about to administer the drug. All nurses were debriefed within 30 minutes of the telephone conversation. Nearly all of the nurses admitted they should not have followed the orders as they were in breach of hospital policy.

There are many similarities between the Milgram and Hoffling experiments. The similarities are that for both of them the focus of the research was obedience, Milgram to see if Americans were as callous as the Germans and Hoffling to see if nurses would obey orders even if they are against hospital policy. Both experiments were done
