Question

If the sum of 20 values is 300, then mean of the data is?

Answer 1

Step-by-step explanation:

mean = sum of value/ no. of value

mean = 300/20

mean = 15

....666....

Answer 2

Given:

No. of observation = 20

Sum of observation = 300

To find:

Mean = ?

Formula to be used:

Mean = $\frac{Sum of observation}{Total number of observation}$

Solution:

Step 1 of 2

As the values required are given directly, we can obtain the mean by substituting the given values in the formula

Mean = $\frac{Sum of observation}{Total number of observation}$

Step 2 of 2

Mean = $\frac{300}{20}$

On cancelling the zero in the units place in numerator and denominator we get,

Mean = $\frac{30}{2}$

Two times of 15 is 30. Thus,  

Mean = 30

Final answer:

If the sum of 20 values is 300, then mean of the data is 30.
