Question

Find the median of 15, 47, 48, 81, 17, 27, 9, 3, 10,75​

Answer 1

Answer:

Arranging the numbers in ascending order :

3,4,9,10,12,15,17,27,47,48,75,81

Median is the middle term of the series, when the series is arranged in ascending/ descending order.

Here, n=12 which is even. For a sequence with even number of terms, the median is given by the following formula:

Median=21(2nth term+(2n+1)th term)

               =21(26th term+(26+1)th term)

               =21(6thterm+(6+1)thterm)

               =21(6thterm+7thterm)

                =21(15+17)

                =21×32

                =16

Hence, the median is 16.

Answer 2

Answer:27.

Step-by-step explanation:

sol).median=?

=arrange in ascending order in the following way:

=3,9,10,15,17,27,47,48,75,81

             10=even.

as the no. of observations is even.

formula= (n+1)/2

=10+1)/2

=6.

∴The median is the six number.
