Answer 2

Solution:

Mean = A + (∑fd/n) * h

= 10 + (185/29) * 1

=10 + 6.3793 * 1

=10 + 6.3793

=16.3793


Median = M = value of (n+1/2)th observation

= value of (30/2)th observation

= value of 15th observation

From the column of cumulative frequency cf, we find that the 15th observation is 20.

Hence, the median of the data is 20.


Mode =
the frequency of observation 15 is maximum (10)

= 15

Hope this will help
