Question

if the 26 english alphabets are taken such that A=1 B=2 C=3 .......Z=26 then find the mean and median of the numbers corresponding to the vowels

Answer 1

A=1, E = 5, I = 9, O = 15 ans U = 21

1,5,9,15,21

median = 'middle' number = 9

mean  = (1+5+9+15+21) / 5  =  10.2 

Answer 2

We have to calculate the mean and median of the vowels in English alphabet.

The vowels are a,e,i,o,u.

According to the english alphabets,

a=1 , e=5, i=9, o=15 and u=21

So the data is:

1,5,9,15,21.

Mean = sum of all observations divided by the total number of observations

Mean = $\frac{(1+5+9+15+21)}{5}$

Mean = $\frac{(51)}{5}$

So, mean = 10.2

Now we will calculate median for the data

1, 5, 9, 15 , 21

Since total number of terms = 5(Odd)

Median = $\frac{(n+1)}{2}$ observation

Median = $\frac{(5+1)}{2}$ observation

Median = 3rd observation.

So, median is 9.
