In the field of research, survey type research is very popular and widely used as a research method. But some times I felt that collecting data by closed ended questionnaire may lead to socially desirable responses or behavior, example - if anyone is conducting a research on "Current Status Professional Development of Secondary Teacher" and the researcher is putting questions about the activities like - Are you a enrolling in refresher courses, are you participating in seminar, workshop or Faculty development programme etc
Then the respondent here may answer in his positive side whether he/she is doing these activities or not (So these type of socially desirable behavior they are giving and happening also). It is very much affecting the authenticity of the data we got from our sample and what we report for the development of the society may be wrong and we are providing to some extend the wrong data. So how can we mitigate or limit or reduce this effect.
