You are working with a healthcare dataset and you observe that a patient's health status influences the probability of missingness in the data. What type of missing data is this?
- MAR
- MCAR
- NMAR
- Not missing data
This would be MAR (Missing at Random) because the missingness is related to an observed data (the patient's health status). The missing data is not random, but it doesn't depend on the unobserved data itself.
