It is very important as failure would result in misleading insights and heavy penalties. You would also need to see data with respect to physical limits. For example, if you are recording environmental temperature in India it should not have value -100C and can be considered a bug. It should be removed before analysis specifically if the outcome of the analysis is minimum temperature or an average temperature in India.
