Question

give me the formula of average?​

Answer 1

Average= sum of all observations/number of observations

For example,

Find the average of 2,3,4,5,6,7,8,9,10,1

So now, sum of all these numbers = 55

Number of total observations= 10

So average= 55/10

= 5.5

Answer 2

Explanation:

Average, which is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.

Formula For Average

represent 'n' number of observations. Then the average of these observations will be given by: Average value = (a + b + c + … )/n ;where n is the total number of observations
