1. Create an Excel spreadsheet that will be capable of calculating a student's final grade in a given course. Keep in mind that weighting is involved in determining the final grade.
□ The scores provided on the next page
□ Category averages
□ The weights used to determine the final weighted grade for the course
□ A labeled cell with the Final course grade that uses a formula to calculate the weighted average grade for the course. If a score is changed in your spreadsheet, your final calculation should recalculate. Please limit your use of Excel functions to those used in the course-packet (for a list see the 'Excel Reference sheet' in Blackboard's 'Excel Help' button.

□ An explanation of your process for using Excel to calculate the weighted average final grade. Were there any assumptions that you made about the scores provided?
□ Analyze and reflect on the results for the student data provided. What is the predicted final course score based on the data provided. What letter grade is this?
□ What is the lowest grade the student would have had to score on the midterm to improve his final course score to the next higher letter grade?
□ Reflect on the impact on the student's final course score for each of the following. Return the changed scores back to the original scores after considering each scenario:
i. If the student received perfect scores on all of the homework?
ii. If the student did not submit the second paper?
iii. If the instructor drops the lowest homework and quiz score for the student?
□ Some students and instructors feel that the weights for the course emphasize the exams too much. Come up with a new weighting system. Explain why you believe the new weights would be an improvement.
□ How would you have to modify (if any) your spreadsheet to calculate grades in a class where scores are out of varying point values for each assignment? For example, in Professor Ivy's class the individual homework grades are recorded as follows: HW1= 6/10, HW2= 36/54, HW3= 25/25... Professor Ivy prefers not want to turn these grades into percentages, because each is out of different points. How else could she find averages for homework in her class?
□ Reflect on your experience creating this spreadsheet - What have you learned from doing this project? Did you encounter any difficulties? What did you notice about Excel spreadsheets and how can this help you in the future?

Create an Excel spreadsheet that will compute the following sample student's data set for the course described below. Assume all scores are out of 100 and that all grades have been recorded for this student.

Grading and Evaluation Rules for PSYC205 Abnormal Psychology Course:
Methods of Evaluation: There will be a Midterm and Final Exam in this class. Two papers will also be assigned. Homework and ten quizzes will also be part of the course grade.
Midterm 25% 90 - 100 A
Final 30% 80 - 89 B
Homework 10% 70 - 79 C
Papers 25% 60 - 69 D
Quizzes 10% 0 - 59 F

A student has the following grades in each category:
Homework: 80, 90, 86, 87, 89, 99, 0, 87, 88, 78, 96, 93
Quiz: 70, 73, 84, 92, 90, 100, 0, 86, 85, 80
Papers: 86, 68
Midterm: 74
Final: 78

□ An explanation of your process for using Excel to calculate the weighted average final grade. Were there any assumptions that you made about the scores provided?

Excel can be used to calculate weighted average grades by first finding the average of each category. the average can be found using Excel's AVERAGE function, or by using Excel's SUM function, then dividing by the number of numbers in that category. These averages are then multiplied by the corresponding weights for that category. The weights used are those supplied in the course syllabus for the class. Make sure to correspond the category with the correct weight given in the syllabus. Do not assign the weights incorrectly or the weighted average grades will be incorrect. The weighted average grade is then summed. This sum gives the Final Course Grade for the student. I assumed that every score in a particular category was worth the same number of points.
