Calculate the mode from the following data:


Monthly salary (in Rs.)



No. of employees



0 - 5000



90



5000 - 10000



150



10000 - 15000



100



15000 - 20000



80



20000 - 25000



70



25000 - 30000



10


Here, the maximum class frequency is 150.

The class corresponding to this frequency is the modal class. modal class = 5000 - 10000


lower limit of the modal class (l) = 5000


Modal class size (h) = 5000


Frequency of the modal class (f1) = 150


Frequency of class preceding the modal class (f0) = 90


Frequency of class succeeding the modal (f2) = 100


Mode is given by,





Mode = 5000 + 2727.27 = 7727.27


Hence, the mode is Rs.7727.27.
