Question

Find :
(i) Mean and
(ii) Median
for the following observations :
10, 47, 3, 9, 17, 27, 4, 48, 12, 15

Answer 1

Mean = 19.2

Median = 27

Explanation:

Mean = sum of terms / number of terms

 = 10 + 47 + 3 + 9 + 17 + 27 + 4 + 48 + 12 + 15 / 10

=  192 / 10

Mean = 19.2

The median is the ((n + 1)/2)th item, where n is the number of values.  

Median of the given series: 10, 47, 3, 9, 17, 27, 4, 48, 12, 15

n = 10

Median = (10+1)/2 = 5.5th term.

Sixth term, 27 will be the median.
