Question

Calculate the mean of 1,2,3,4,5,6

Answer 1

The mean of 1 , 2 , 3 , 4 , 5 , 6 is 3.5

Given :

The observations 1 , 2 , 3 , 4 , 5 , 6

To find :

The mean of 1 , 2 , 3 , 4 , 5 , 6

Solution :

Step 1 of 2 :

Calculate sum of the observations

Here the given observations are 1 , 2 , 3 , 4 , 5 , 6

Number of observations = 6

Sum of the observations

= 1 + 2 + 3 + 4 + 5 + 6

= 21

Step 2 of 2 :

Find the mean

The required mean

Answer 2

mean = 3.5

Explanation:

the mean is calculated as

mean =
`(sum)/(count)` =
`(1+2+3+4+5+6)/(6)` =
`(21)/(6)` = 3.5
