Answer :
- Mean is 26
Given :
- 25 , 30 , 27 , 23 and 25
To find :
- Mean
Solution :
Given,
- 25 , 30 , 27 , 23 and 25
As we know that,
- Mean = Sum of observations/Total number of observations
where , Sum of observations is 25,30,27,23,25 and Number of observations is 5
Given the mean of numbers,
》Mean = 25 + 30 + 27 + 23 + 25 / 5.
》Mean = 130/5
》Mean = 26
Hence , Mean is 26
More Explanation :
- Mean is nothing but the average of group of numbers
- First we have to add all numbers then after we have to divide by how many numbers are there
- Example: 3 , 6 , 2 and 4
- 3 + 6 + 2 + 4 / 4 = 16/4 = 4
