Answer:
B) In the field study, it is much harder to control variables than in an experiment
Explanation:
Field study and laboratory experiments are both employed by scientists in discovering answers to investigations. However, while field studies are conducted in a natural or real world scenario, experiments are carried out in the confines of a laboratory.
One major difference between an experiment and field study is that IT IS DIFFICULT TO CONTROL VARIABLES IN A FIELD STUDY THAN IN AN EXPERIMENT. Experimental Research usually occurs under strict controlled conditions where only one variable is being tested at a time and the other controlled. However, in a field study, it becomes difficult to have only one variable being tested as several variables come to play.
