The mode

Merits

i.  This can be determined from incomplete data given the observations along with the highest frequency are already known

ii.  The mode has some applications in business

iii.  The mode can be simply defined

iv.  This can be determined simply from a graph

Demerits

i.  If the data is quite ungrouped and large, determination of the mode can be rather cumbersome

ii. Employ of the formula to calculate the mode is unfamiliar to most business people

iii. The mode may occasionally be non-existent or there may be two modes for a described set of data. Hence in such a case a single mode may not exist
