Description: The ‘non-response bias’ is a phenomenon that occurs in statistical research when certain individuals selected to participate in a survey or study do not respond. This type of bias can compromise the validity of the results, as the lack of response from certain groups can lead to a sample that is not representative of the entire population. The reasons behind non-response can vary, including lack of interest, difficulty accessing the survey, or even the perception that their opinion is not relevant. This bias is particularly problematic in studies aiming to obtain a general view of attitudes or behaviors of a population, as it can result in erroneous or biased conclusions. Therefore, it is crucial for researchers to implement strategies to minimize this bias, such as using reminders, incentives for participation, or designing more accessible surveys. Identifying and correcting non-response bias is essential to ensure the integrity of the collected data and the validity of the inferences made from it.
