Survey Method in Psychology
- There are certain psychological problems which if a psychologist tries to study taking a small sample then he can’t do that in a proper and scientific manner. To study such problems it is compulsory to have a large sample and must include persons from different sections of the society. To study the attitude towards child rearing practices in society, to study the pre marital sexual relationships, to study the problems generated because of drug abuse, these are some of the problems which needs a large sample that must be the representative of all the sections of the society. Therefore to study these type of problems psychologists uses survey method.
Merits and demerits of survey method:
The major merits of this method are as follows:
- The major merit of this method is that using the scores for many persons can be collected in less time.
2) As persons under study belong to different sections of the society therefore the conclusions drawn from these studies have a property of generalization. In other words conclusion drawn from this method can be considered as true from many people, means survey method has high external validity.
The demerits of survey methods are:
- 1) This method cannot be used on infants.
2) There seems to be a contraction about validity on the data collected for any problem using this method. For example the informations collected through postal questionnaire are true; one can’t say it for sure. It might possible that the answers us given by someone else rather than the expected person. It is also possible that the person might answer only few questions rather than the complete questionnaire. Therefore it can be said that the survey method has less validity. Inspite of these demerits this method is used very much by psychologists.
