Many times such an examination may be needed for the residuals after fitting various models. For most multivariate analyses, it is thus very important that the data indeed follow the multivariate normal, or if not exactly at least approximately. If the answer to such a query is affirmative, it can often reduce the task of searching for procedures which are robust to the departures from multivariate normality.
