Create A Spreadsheet For Instructor Use To Calculate

Create a spreadsheet that your instructor could use to calculate final

Create a spreadsheet that your instructor could use to calculate final averages and letter grades for a fictitious class. Use the point values below for pop quizzes, regular exams, mid-term, final, and homework. Each individual grade will be recorded as points earned out of 100 total possible. Pop quizzes (4) 10% (drop lowest grade) Regular exams (4) 30% (drop lowest grade) Mid-Term 20% Final 20% Homework (5) 20% (drop lowest grade) 100% The spreadsheet should use a similar design and features of the spreadsheet created in your Excel tutorial for assignment 2.

More specifically, the following requirements must be met:

1. Each student record should be on one row and each grade item or calculated value should be in one column similar to the tutorial

2. A table that includes cutoff’s for each grade level, i.e. 90 for A, 80 for B, etc.

3. Column Headings

4. A minimum of 5 fictitious student records with grades entered for each student.

5. Columns for total points in each category of grades (Pop quizzes, Regular exams, Mid-Term, Final and Homework). Create a table with the percentages for each grade category as listed in the instructions above. Use absolute cell referencing to use the percentages from the table to calculate total points for each category. This design would allow easy modification of the percentages so the modifications to the table would be reflected in each individual category.

6. A calculated final average.

7. A final letter grade. Use an IF statement and absolute cell referencing for grade cutoff’s from the table created in #2 above (similar to what was done in assignment 2 tutorials). Reference the grade level cut-off levels from the table so the cut-off levels for each letter grade can be changed in the table and reflected in each individual letter grade.

8. A class average for each individual grade item, combined grade categories (Pop quizzes, Regular exams, Mid-Term, Final and Homework), and final average. Use the average function.

9. The highest (use max function) grade for each individual grade item, combined grade categories (Pop quizzes, Regular exams, Mid-Term, Final and Homework), and final average.

10. The lowest (use min function) grade for each individual grade item, combined grade categories (Pop quizzes, Regular exams, Mid-Term, Final and Homework), and final average.

11. Center all column headings

12. Bold columns for total pop quiz points, total exam points, total homework points, mid-term points, final average, and letter grade.

13. Format all calculated values (not individual scores) as number with one decimal point.

14. Put your name at the top of the spreadsheet.

15. Upload your completed assignment to the Dropbox for assignment 2 in D2L by the due date. Verify that you assignment is uploaded correctly.

This can be accomplished by opening the uploaded file to verify the file opens properly. This is an individual assignment and you should create this spreadsheet on your own. Keep in mind that the tutorial is a learning tool and completion of the tutorial is not the assignment. You should start with a blank spreadsheet and build the assignment from scratch.

Create a spreadsheet that your instructor could use to calculate final

In contemporary educational settings, grading spreadsheets play a pivotal role in accurately computing students’ final grades. An effective grading spreadsheet should be user-friendly, adaptable, and comprehensive, encompassing multiple grade items and enabling easy modifications. In this paper, I will design a detailed Excel spreadsheet tailored to calculate final course averages and letter grades based on specified grading policies, employing best practices in spreadsheet design and Microsoft Excel features.

Design and Structural Components

The foundational element of the spreadsheet involves organizing student data systematically, with each student occupying a single row and each grade component represented as a separate column. I will include at least five fictitious student records to illustrate the functionality. The grades for individual assignments—pop quizzes, regular exams, mid-term, final, and homework—are entered as numerical scores out of 100 points. The layout ensures clarity and ease of data entry by labeling columns with descriptive headings aligned centrally, which enhances readability.

Grade Components and Weighting System

Following the assignment instructions, I will incorporate a dedicated table that specifies the weightings for each category:

• Pop Quizzes: 10% (drop lowest among four attempts)
• Regular Exams: 30% (drop lowest among four attempts)
• Mid-Term Exam: 20%
• Final Exam: 20%
• Homework: 20% (drop lowest of five scores)

This table is crucial as it utilizes absolute cell referencing for the weight percentages, enabling dynamic recalculations if weights are modified. The total points for each category per student are calculated by summing best grades after dropping the lowest, multiplied by the category weight, and then stored in dedicated columns.

Calculations and Logic Implementation

To accurately compute total points, I will utilize Excel functions such as MIN to identify the lowest scores and remove them from the sum — for example, summing the highest three pop quizzes out of four. This ensures fair scoring aligned with dropping the lowest. The same approach applies to homework and exams where applicable.

The final numeric grade is calculated by summing all category scores, which are derived by multiplying the summed best grades by their respective weights. The total grade percentage is then translated into a letter grade by employing nested IF statements referencing the grade cutoff table. These cutoffs are stored in accessible cells, making them simple to update for curriculum adjustments.

Performance Metrics and Summary Statistics

To provide an overview of class performance, I will compute class averages, maximum, and minimum scores for each grade component, category totals, and the overall final grade. The functions AVERAGE, MAX, and MIN are applied to relevant ranges, offering insights into student performance variability and overall class performance.

All numeric outputs, including scores and final grades, are formatted to display one decimal point for consistency and professionalism. Column headings are centered, and key columns such as total category points, overall final grade, and letter grades are bolded to highlight importance.

Additional Considerations

The spreadsheet includes the instructor's name at the top to personalize the document. It is built from scratch, emphasizing fundamental Excel skills and best practices, rather than copying from tutorials. After completing the design, the file must be uploaded to the designated D2L Dropbox, with verification of successful upload by opening the file to confirm functionality.

Conclusion

This project demonstrates the ability to create a comprehensive, adaptable grading spreadsheet that can handle multiple grading components and dynamic grading scales. By leveraging Excel functions, referencing techniques, and structural organization, the designed spreadsheet serves as a practical tool for instructors to accurately calculate and communicate student performance.
