Response Bias: Response bias refers to systematic errors introduced into survey responses due to factors such as social desirability, interviewer influence, or respondent misunderstanding. It can impact the accuracy of face-to-face interviews if respondents do not provide truthful or accurate answers.
Non-Response Bias: Non-response bias occurs when certain individuals selected for a survey choose not to participate. This can lead to skewed results if those who choose not to respond have different opinions than those who do respond.
Interviewer Effect: The interviewer effect refers to the impact that interviewers themselves may have on respondents' answers. Factors such as tone of voice, body language, or personal biases can influence how respondents answer questions.
