You notice that the data from some weather sensors is missing because the sensors malfunctioned when the temperature dropped below a certain level. What type of missing data does this represent?
- MAR
- MCAR
- NMAR
- Not missing data
This would be MAR (Missing at Random) because the missingness is related to an observed data (the temperature). The missing data is not random, but it doesn't depend on the unobserved data itself.
