Question

The arithmetic mean of 20,11,21,25,23,14 is

Answer 1

Step-by-step explanation:

Arithmetic mean = sum of all observations/total numbe

total number of observation

r$20 + 11 + 21 + 25 + 23 + 14 = 144$

144/6 = 102.33

ARITHMETIC MEAN = 102 .33

Answer 2

The required mean = 19

Given :

The observations 20 , 11 , 21 , 25 , 23 , 14

To find :

The mean

Solution :

Step 1 of 2 :

Write down the given data

Here the given observations are 20 , 11 , 21 , 25 , 23 , 14

Number of observations = 6

Sum of the observations

= 20 + 11 + 21 + 25 + 23 + 14

= 114

Step 2 of 2 :

Find the mean

The required mean

$\displaystyle \sf{ = \frac{Sum \: of \: the \: observations}{Number \: of \: observations} }$

$\displaystyle \sf{ = \frac{114}{6} }$

$\displaystyle \sf{ = 19}$
