$\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}$

$\implies$ Here the data has been given to us in the question that is 9, 11, 8, 20, 10, 16, 12. Now the question has asked us to find out the average of given data.

⛤ HOW TO DO:-

$\to$ Here to find the average of the given data we have to do the sum of all the observations. Then after we need to count the number of observations and divide the sum by the no. of observations. The final digits will be our answer.

----------------------

ANSWER:-

⇉ The average of the given data is 10.75.

GIVEN:-

⟶ Data = 9, 11, 8, 20, 10, 16, 12

TO FIND:-

• Here we have to find the average of the given data.

SOLUTION:-

• To find the average follow the steps given below:-

1. Do the sum of all observations.
2. Count the number of observations.
3. Divide the sum of observations by the number of observations.
4. Final digits will be the average.

We know that:-

$\pink {\bigstar} \: \underline{\boxed{\rm\purple {Average = \dfrac{Sum \: of \: observations}{No. \: of \: observations}}}}$

----------------------

So let's solve it!

• Finding the average:-

➤ Average = 9 + 11 + 8 + 20 + 10 + 16 + 12

➤ Average = 9 + 11 + 8 + 20 + 10 + 16 + 12 = 86

➤ Sum of observations = 86

➤ No. of observations = 8

$\dashrightarrow \tt{Average = \dfrac{86}{8}}$

$\dashrightarrow \tt{Average = \dfrac{ \not8 \!\!\!\not6}{ \not8}}$

$\dashrightarrow \tt{Average = \dfrac{ \not8 \!\!\!\not6}{ \not8} = 10.75}$

$\pink {\odot} \: \overline{\boxed{\rm\green {Average = 10.75}}}$

Thus, we got the answer.

So let's solve it!

Finding the average:-

➤ Average = 9 + 11 + 8 + 20 + 10 + 16 + 12

➤ Average = 9 + 11 + 8 + 20 + 10 + 16 + 12 = 86

➤ Sum of observations = 86

➤ No. of observations = 8
