Question

find the median of first 8 positive multiples of 2

Answer 1

Hey there!

First 8 positive multiples of 2 = 2 , 4 , 6 , 8 , 10 , 12 , 14 , 16 .

Here, Number of terms is 8 , which is odd number.

For a data with n observations, where n is even, Median is the Arithmetic mean of n/2 and n/2+1 terms

In this case,
Median = Arithmetic mean of 8/2 , 8/2 + 1 terms

= Mean of 4 , 5 terms

= Mean of 8 , 10

= 8 + 10/2

= 9 .

Therefore, Median of first 8 positive multiples of 2 is 9

Answer 2
