Question

b. Find the average (Mean) of the data: 12,14,16,18,20,22,24.​

Answer 1

Given data:-

• 12, 14, 16, 18, 20, 22, 24.
• No. of observation = 7

To find:-

• Average (Mean) of the data.

Formula used:-

• Average = $\dfrac{Sum\:of \:observation}{No.\:of\: Observation}$

Solution:-

$Average\:=\dfrac{Sum\:of \:observation}{No.\:of\: Observation}$

$=\dfrac{12 + 14+ 16+ 18+ 20+ 22+ 24}{7}$

$=\dfrac{126}{7}$

$=18$

Hence, the Average (Mean) of the given data is 18.
