The weight of coffee in 70 packets are shown in the following table


Determine the model weight.

In the given data, the highest frequency is 26, which lies in the interval 201 - 202

Here, l = 201,fm = 26,f1 = 12,f2 = 20 and (class width) h = 1




= 201 + ()


= 201 + ()


= 201 + 14/20


= 201 + 0.7


= 201.7g


Hence, the modal weight is 201.7 g.
