Assign letter grades to students based on their numerical scores
Assigning letter grades to students based on their numerical scores can be easily managed using Excel's IF and Nested IF functions. This article will demonstrate how to use these functions to assign letter grades efficiently.
Example
Here's an example table showing students' numerical scores and their assigned letter grades:
| Student Name | Score | Grade |
|---|---|---|
| Alice | 92 | A |
| Bob | 78 | C |
| Charlie | 85 | B |
| David | 63 | D |
| Eve | 56 | F |
Exercise
Input the scores for another set of students in the table and use the following functions to assign the correct letter grades based on these criteria:
- A for scores 90 and above
- B for scores between 80 and 89
- C for scores between 70 and 79
- D for scores between 60 and 69
- F for scores below 60
Solution
When you input the scores into the Excel sheet, the formula in the "Grade" column will automatically assign the correct letter grade based on the specified criteria:
The nested IF function in the "Grade" column evaluates the score and assigns the appropriate letter grade. The formula used is:
=IF(B2>=90, "A", IF(B2>=80, "B", IF(B2>=70, "C", IF(B2>=60, "D", "F"))))This formula checks the following conditions:
- If the score in cell B2 is greater than or equal to 90, the grade is "A".
- If the score is between 80 and 89, the grade is "B".
- If the score is between 70 and 79, the grade is "C".
- If the score is between 60 and 69, the grade is "D".
- For scores below 60, the grade is "F".
