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

Answer»

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.
