. The following frequency distribution gives the monthly consumption of electricity of68 consumers of a locality

Best Answer

Solution: The cumulative frequency of the table can be represented as:

Hence,

Median class = 125-145

Cumulative frequency = 42

Lower limit, l = 125

cf = 22

f = 20

h = 20

Hence,

Median can be calculated as:

Now, mode can be calculated as:

Modal class = 125-145

l = 125

h = 20

f1 = 20

f0 = 13

f2 = 14

Hence,

Mean, Median and Mode are more or less equal in this distribution.
