Arithmetic mean the average of a set of numerical values, as calculated by adding them together and dividing by the number of terms in the set.
Lets take 10 random numbers and calculate Arithmetic mean
25,45,35,77,55,34,87,56,54,67
A.M = 25 + 45 + 35 + 77 + 55 + 34 + 87 + 56 + 54 + 67/10
A.M = 535/10
A.M = 53.5

Estimation of Arithmetic Mean of Marks in Different Subjects
Subject: Mathematics
- Classmate 1: 80
- Classmate 2: 75
- Classmate 3: 82
- Classmate 4: 78
- Classmate 5: 85
- Classmate 6: 88
- Classmate 7: 79
- Classmate 8: 83
- Classmate 9: 81
- Classmate 10: 87
Estimation:
To estimate the arithmetic mean of marks in Mathematics, we sum up the marks of all the classmates and divide it by the total number of classmates.
Estimation: (80 + 75 + 82 + 78 + 85 + 88 + 79 + 83 + 81 + 87) / 10 = 818 / 10 = 81.8
Actual Calculation:
To calculate the actual arithmetic mean of marks in Mathematics, we add up the actual marks of all the classmates and divide it by the total number of classmates.
Calculation: (80 + 75 + 82 + 78 + 85 + 88 + 79 + 83 + 81 + 87) / 10 = 818 / 10 = 81.8
Verification:
The estimation for the arithmetic mean of marks in Mathematics is 81.8. After the actual calculation, we found that the actual arithmetic mean is also 81.8. Therefore, the estimation accurately represents the actual mean.

- Classmate 6: 88
- Classmate 7: 72
- Classmate 8: 79
- Classmate 9: 81
- Classmate 10: 84
Estimation:
Estimation: (75 + 78 + 80 + 82 + 85 + 88 + 72 + 79 + 81 + 84) / 10 = 804 / 10 = 80.4
Actual Calculation:
Calculation: (75 + 78 + 80 + 82 + 85 + 88 + 72 + 79 + 81 + 84) / 10 = 804 / 10 = 80.4
Verification:
The estimation for the arithmetic mean of marks in Science is 80.4. After the actual calculation, we found that the actual arithmetic mean is also 80.4. Therefore, the estimation accurately represents the actual mean.
