Calculating the average grade for a group of students is a straightforward process that involves summing up all the grades and dividing by the number of students. This guide provides an example and a sample Excel sheet to help you perform this calculation easily.
Example
Below is an example of a table with student grades. This table will be used in the embedded Excel sheet to calculate the average grade.
| Student | Grade |
|---|---|
| Alice | 85 |
| Bob | 90 |
| Charlie | 78 |
| Diana | 92 |
| Edward | 88 |
Exercise
Write two formulas for this data:
- Alice: 85
- Bob: 90
- Charlie: 78
- Diana: 92
- Edward: 88
- The first formula sums up cells and divides them by the cell number.
- The second one uses the AVERAGE function.
Solution
There are two ways of entering the formula:
1. It takes all cells, sums them, and divides them by the number of cells: =(B2+B3+B4+B5+B6) / 5
2. The second method uses the formula =AVERAGE(B2:B6) to calculate the average grade. Here's how it works:
- The grades are entered in cells B2 to B6.
- The formula
=AVERAGE(B2:B6)calculates the sum of these grades and divides by the number of students (5 in this case). - The result is displayed as the average grade.
This simple calculation helps in quickly assessing the overall performance of the group of students. The embedded Excel sheet ensures that the calculation is accurate and can be reused for different sets of grades.
