Answer:
Limitations: (i) The greatest drawback of this method is that algebraic signs are ignored while taking the deviations of the items. ... If mean deviation is computed from mode that is also not scientific because the value of mode cannot always be determined. (iii) It is not capable of further algebraic treatment.

One of the drawbacks of the mean deviation is that since it is not rigidly defined, different central tendencies like mean, median and mode can be used to find the answer and all of them will produce different results. Furthermore, these result cannot even be used for further algebraic treatment.
