Question

Find the mode for the following series:
2.5, 2.3, 2.2, 2.2, 2.4, 2.7, 2.7, 2.5, 2.3, 2.2, 2.6, 2.2.

Answer 1

Arranging the data in the form of a frequency table, we have:

Value	Tally bars	Frequency
2·2	IIII	4
2·3	II	2
2·4	I	1
2·5	II	2
2·6	I	1
2·7	II	2

We see that the value 2·2 has the maximum frequency i.e., 4.
So, 2·2 is the mode for the given series.
