1. EXPERIMENTAL METHOD

2. What is experimental method or scientific method Experimental method is considered to be the most scientific and objective method for studding behavior. It is observation under controlled conditions. In this method the investigator tries to study the cause and effect relationships regarding human behavior by performing experiments. There are three types of variables. Independent variable, depend variable and intervening or controlled variable.

3. CHARECTERISTICS It is essentially requires at least two persons, the experimenter and the subject. Usually the experimental method is applied one person in a random order

4. Merits of experimental method It is the most systematic method and condition can be completely controlled. The data collected can be analyzed in an objective manner and so it is reliable. A cause effect relationship of individuals behavior can be established. The findings of experimental method are open to critical examination and verification. It discards subjective experiments.

5. Demerits of experimental method As human behavior is changeable, identical behavior of the same individual not occur even under identical c0nditions at different times. This experimental method is costly and time consuming. This method must have specialized skills to conduct experiments. The tools used in experiments may not be satisfactory and therefore the obtained data may not be reliable.

6. It is extremely difficult to controlled all other causative factors except the one under study. The experimental method can produce results of probability and not certainly.
