Concept:Observation method is the most reliable way to study child behaviour because it records natural actions without interference.
Explanation:In the observation method, the researcher watches the child’s behaviour systematically.
It records behaviours as they occur in real situations.
The observer does not influence or interfere with the child.
This makes the data authentic and natural.
Interview method relies on verbal responses, which may not be accurate for young children.
Sociometry measures relationships, not overall behaviour.
Inspection method checks performance against fixed standards, not natural behaviour.
Therefore, observation is the best method for studying child behaviour.
Answer:The best method for the study of child behaviour is the observation method.
