\textbf{Given:}

\textsf{Data is}

\mathsf{1,2,3,4,5,6,7}

\textbf{To find:}

\textsf{The mean of the given data}

\textbf{Solution:}

\underline{\textsf{Formula used:}}

\textsf{The Arithmetic mean of first n natural numbers is}

\mathsf{\dfrac{n+1}{2}}

\mathsf{Consider,}

\mathsf{1,2,3,4,5,6,7}

\textsf{These are first 7 natural numbers}

\boxed{\mathsf{Mean=\dfrac{n+1}{2}}}

\implies\mathsf{Mean=\dfrac{7+1}{2}}

\implies\mathsf{Mean=\dfrac{8}{2}}

\implies\boxed{\mathsf{Mean=4}}

\textbf{Find more:}

the mean of 4 observations is 5 and the mean of 6 observation is 3 then find the mean of total 10 observations​

Given:

1.2.3.4.5.6.7

To Find:

Mean

Solution:

To find the mean, first, we need to add the given data then divide it with total observations.

1.2.3.4.5.6.7

Sum of the given data:

=> 1 + 2 + 3 + 4 + 5 + 6 + 7

=> 28.

Total observations: 1.2.3.4.5.6.7 = 7

Finding Mean :

mean \:  =  \dfrac{sum \: of \: observations}{total \: observations}

 =  > \dfrac{28}{7}

 =  > 4

Hence, The mean of the given data is 4
