5.32 I FUNDAMENTALS OF BUSINESS MATHEMATICS AND STATISTICSMeasures of Central Tendency and Measures of Dispersion
(B) For Simple Frequency Distribution Discrete Series.
To Find the mode from the following Table :
Height (in inches) No. of Persons

69 2Frequencies given below, in column (1) are grouped by two’s in column (2) and (3) and then by three’s in
columns (4), (5), and (6). The maximum frequency in each column is marked by Bold Type. We do not find
any fixed point having maximum frequency but changes with the change of grouping. In the following
table, the sizes of maximum frequency in respect of different columns are arranged.
