Question

) Find the mean and median of first eight natural numbers.​

Answer 1

Answer:

The first eight natural numbers are 1, 2, 3, 4, 5, 6, 7, 8

∴ Sum of these observations =1 + 2 + 3 + 4 + 5 + 6 + 7 + 8=36

and, number of their observations = 8

∴ Required mean = \frac { 36 }{ 8 } = 4.5

Answer 2

Answer:

mean= 1+2+3+4+5+6+7+8/8

=36/8

=4.5

median =1, 2,3,4,5,6,7,8

middle term is 4,5

median =4+5/2

=9/2

=4.5
