Ethical Issues in Data Collection (Contd.) The Rights of the Respondents Can Be Violated By: • Disguising the purpose of a particular measurement • Deceiving the prospective respondent as to the true duration of the interview • Misrepresenting the compensation in order to gain cooperation • Not mentioning that a follow-up interview will be made • Using projective tests and unobtrusive measures to circumvent the need for a respondent’s consent • Using hidden tape recorders http://www.drvkumar.com/mr9/
