Question

find the mean and median of first 10 odd natural numbers
​

Answer 1

First ten odd numbers:-

1,3,5,7,9,11,13,15,17,19

Mean:-

→1+3+5+7+9+11+13+15+17+19+

→100

Mean:-100/10

=10

Median:+

→1,3,5,7,9,11,13,15,17,19

→9

Hope it helps ✌.

Answer 2

Given:- find the mean and median of first 10 odd natural numbers .

Answer :- We know that mean is defined as the sum of observations divided by number of observations .

$\boxed{\bf{\red{\dag Mean=\dfrac{x_1+x_2+x_3+x_4+............+x_n}{n}}}}$

First 10 odd natural numbers are : 1 , 3 , 5 , 7 , 9 , 11 , 13 , 15 , 17 , 19 .

And sum of first n odd natural numbers is given by n² .

=> Mean = Sum of observations/ Number of observations

=> Mean = 1+ 3 + 4 + ........+ 19 / 10

=> Mean = 10² / 10.

→ Mean = 10 .

★ Hence the required mean is 10 .
