What is the term for when participants intentionally skip questions?

The term that describes the situation when participants intentionally skip questions is missing data. This occurs when respondents do not provide an answer to one or more questions in a survey or study. This can happen for various reasons, including a lack of knowledge about the topic, a desire to avoid sensitive questions, or simply an oversight. Missing data is a critical consideration in research and data analysis, as it can impact the validity of the findings and the overall conclusions drawn from the data set. Researchers must address and analyze missing data appropriately to ensure that their study results are reliable and accurate.
