What is missing data in research methodology? Missing data (or missing values) is defined as the data value that is not stored for a variable in the observation of interest . The problem of missing data is relatively common in almost all research and can have a significant effect on the conclusions that can be drawn from the data [1].
What is a useful strategy to use when you are missing data? Answer: Multiple imputation is another useful strategy for handling the missing data.
