Response bias refers to the tendency of individuals to answer survey questions or provide information in a way that is not completely accurate or truthful. This can be influenced by a variety of factors, such as social desirability, personal beliefs, or the desire to please the person asking the questions. Response bias can lead to inaccurate data and can skew the results of research or surveys. It is important for researchers to be aware of and account for response bias in order to obtain reliable and valid data.
