Excel Vlookup to calculate grades

Introduction

This tutorial will guide you through using the VLOOKUP function in Excel 2007 to calculate grades based on a predefined grading table. VLOOKUP is a powerful tool that allows you to search for a value in one column and return a corresponding value from another column, making it ideal for tasks like grade calculations.

Step 1: Prepare Your Data

Before using the VLOOKUP function, ensure you have two key sets of data:

• A grading table that defines the scores and corresponding grades.
• A list of student exam scores.

Grading Table Example

| Score Range | Grade | |-------------|--------| | 0 | F | | 55 | D- | | 62 | D | | ... | ... |

Student Scores Example

| Student Name | Score | |--------------|-------| | John | 60 | | Jane | 72 | | ... | ... |

Step 2: Start the VLOOKUP Formula

1. Click on the cell where you want to display the grade (e.g., H2).
2. Begin your formula by typing = to indicate that you are entering a formula.
3. Type VLOOKUP( to start the VLOOKUP function.

Step 3: Define the Lookup Value

1. Specify the cell that contains the score you want to look up. For example, type G2 if your scores are in column G.
2. Follow this with a comma.

Step 4: Specify the Table Array

1. Select the range of the grading table. For example, if your grading table is in cells J2 to K8, enter J2:K8.
2. To make this range absolute (so it doesn’t change when you drag the formula), press the F4 key on your keyboard.
3. Add another comma after the table range.

Step 5: Define the Column Index Number

1. Indicate which column from the grading table contains the values you want to return. For grades, this would typically be the second column, so type 2.
2. Close the bracket to finish your function.

Example Formula

=VLOOKUP(G2, $J$2:$K$8, 2)

Step 6: Apply the Formula to Other Cells

1. After entering the formula in H2, press Enter. Excel will return the corresponding grade for the score in G2.
2. To apply this formula to other students, click on the small square at the bottom right corner of cell H2 (the fill handle) and drag it down through the cells in column H.

Conclusion

You have now successfully used the VLOOKUP function in Excel to calculate grades based on student scores. This method allows for quick and efficient grade retrieval from a grading table.
