The mode of an ungrouped frequency distribution can be determined if the value of an item having maximum number of frequency.
Example:
Find the mode of the following data.
 
Height (in cm)\(145\)\(150\)\(162\)\(132\)\(138\)
Number of students\(5\)\(6\)\(12\)\(25\)\(3\)
 
Solution:
 
Here, the number of students is the frequency. The maximum frequency is \(25\).
 
Therefore, the height having the maximum number of frequency is \(132\) \(cm\).
 
Hence, \(132\) is the mode.
