Question

Find the mean of following 8,10,12,14,16​

Answer 1

Given:

The data -

• 8, 10, 12, 14, 16

What To Find:

We have to find -

• The mean of the data.

Formula Needed:

The formula is -

$\pmb{Mean = \dfrac{Sum \: of \: observation}{No. \: of \: observation}}$

Where -

• No. of observation = 5

Solution:

Using the formula,

$\sf {\implies Mean = \dfrac{Sum \: of \: observation}{No. \: of \: observation}}$

Substitute the values,

$\sf {\implies Mean = \dfrac{8 + 10 + 12 + 14 + 16}{5}}$

Add the numerators,

$\sf {\implies Mean = \dfrac{60}{5}}$

Divide 60 by 5,

$\sf {\implies Mean = 12}$

Final Answer:

∴ Therefore, the mean of the following data is 12.

Answer 2

Question :-

• Find the Mean of the Following 8 , 10 , 12 , 14 & 16 .

Answer :-

• Mean of the Data = 12 .

$\rule {180pt}{2pt}$

Given :-

• Data = 8 , 10 , 12 , 14 & 16

To Find :-

• Mean = ?

Solution :-

As per the provided information in the given question, we have been given that the Data is 8 , 10 , 12 , 14 & 16 . And, we have been aksed to calculate the Mean .

Formula Required :-

$\bigstar \: \: \boxed { \sf \pink { \: Mean \: = \: \dfrac{Sum \: of \: Observation \: } {No. \: of \: Observation}} }$

Where ,

• No. of observations is 5 .

Therefore , by Substituting the given values in the above Formula :-

$\longmapsto \: \: \sf{Mean \: = \: \dfrac{8 \: + \: 10 \: + \: 12 \: + \: 14 \: + \: 16}{5} }$

$\longmapsto \: \: \sf{Mean \: = \: \dfrac{ 60}{5 } }$

$\longmapsto \: \: \textbf { \textsf{Mean = 12}}$

Hence :-

• Mean = 12
