Background:This project is designed to practice the use of formulas, built-in MS Excel Functions, What-If Analysis. For this project, you will upload your Excel file to Canvas so that it can be accessed by just clicking on the file’s link. Directions:ï‚·Follow the instructions listed on the next pages to create and complete the Recitation Project file.ï‚·Enter your name on cell A1 of the worksheet.ï‚·Submit your RecitationProject.xlsxfile to Canvas using the Canvas->Assignments link.Page 1 of 5

Instructions:Grades spreadsheet 1.Go to Canvas â†’ CS170 -> Grades page and then do the following: a)Start Excel, create a Blank worksheet. b)Select the cell C3 on the worksheet and enter: Assignment 1 on it. c)Select the Fill Handle on C3 and drag down to transfer the entry all the way to cell C13. Youâ€™ll see that the numbers have been adjusted automatically andAssignment 2, Assignment 3, etc. appear on the C column. Ensure that Assignment 11 is on on C13. d)Rename the worksheet as Grades. e)Type the following five entries on cells C14 to C18:Exam1, Exam 2, Instructor Extra Credit, TA Extra Credit, Recitation Project. f)Add the following three entries to the list of activities on the C column (below C18): Final Exam Part 1, Final Exam Part 2,Final Exam Part 3. g)Starting on the cell D3, enter the numeric scores that you have obtained so far as listed in the Scores column of the Grades page. h)Starting on the cell E3, type the maximum number of points possible for each Grades Item as listed in the Outof column of the Grades page.ï‚·2 points for Assignment 1ï‚·20 points for the other Assignments and the Recitation Projectï‚·80 points each for Exams 1 and 2ï‚·120 for the Final Exam (simply ignore it if this entry is not listed yet)ï‚·Note: If there is an item for which you do not have a grade yet, do notenter the maximum points for it.Page 2 of 5

i)On row 28 do the following:ï‚·Enter the label â€œTotalsâ€ on C28ï‚·The total points obtained will be calculated on D28. Since there might be some blank cells, an appropriate function for this cell is SUMIF.ï‚·Arguments for SUMIF:ï‚·range: the list of scores on the D column (including blank cells for the activities with no scores yet)ï‚·criteria: greater than or equal to 0 (express this using Excel notation)ï‚·sum_range: the list of scores on the D column (including blank cells for the activities with no scores yet)ï‚·Copy the function from D28 to E28 using the fill handle. j)On row 29:ï‚·Enter the label â€œPerformanceâ€ on C29.ï‚·On D29 enter a formula to calculate your Performance % by simply dividing your total points by the total maximum points (those numbers are on row 28).ï‚·Format your performance with Percentage style with 1 decimal. k)On G3, start a table of equivalences between % points (on the G column) and letter grades (on the H column). Use the following Grading table which is derived from the Grading section of the Syllabus (once completed the Grading table should start at G3 and end at H9.

On row 30:ï‚·Enter the label Letter Grade on C30. ï‚·On D30 insert the VLOOKUP function to calculate the current letter grade based on your Performance % and the Grading table created on G3:H9.ï‚·The arguments for the VLOOKUP function are:ï‚·lookup_value: your numeric performance % (from D29).ï‚·table_array: the table that converts percentages into letter grades which you created starting on G3.ï‚·col_index_num: 2 (since the second column contains the letter grades). m)What-If Analysis: ï‚·Now that you have calculated a letter grade for your current scores, you will run some simulation Scenarios to evaluate the possible effect of the Final Exam.ï‚·The formula entered on cell D28 which currently contains SUMIF needs tobe modified to process the hypothetical Final Exam scores for each of its parts.ï‚·To process the Second Chance option, the formula on D28 needs to be expanded. Instead of just =SUMIF(…) the format will be: =SUMIF(…) + IF(…) + IF(…)ï‚·The first IF that needs to be added â€“ use the Formula bar to add it – willhave the following arguments (use Excel notation; value_if_false doesnot need an entry):ï‚·Logical_test:2 x Score of Final Exam Part 1 > Score of Exam 1ï‚·Value_if_true:(2 x Score of Final Exam Part 1) â€“ Score of Exam 1ï‚·Value_if false:At this point D28 should have the following format:=SUMIF(…) + IF(…)Page 4 of 5

ï‚·The second IF that needs to be added will have the following arguments (use Excel notation; value_if_false does not need an entry):ï‚·Logical_test:2 x Score of Final Exam Part 2 > Score of Exam 2ï‚·Value_if_true:(2 x Score of Final Exam Part 2) â€“ Score of Exam 2ï‚·Value_if false: At this point D28 should have the following format:=SUMIF(…) + IF(…) + IF(…)ï‚·Some numbers have to be added to the rows where Final Exam Part 1, Final Exam Part 2 and Final Exam Part 3 are located.ï‚·On the D column of those rows place some hypothetical numbers (Example: 32 on each of those three cells).ï‚·The E column for those rows should have 40 on those cells since the maximum score for each part of the Final Exam is 40.ï‚·At this point, the What-If Analysis may start. Click on D30, then on the Data tab â†’ What-If Analysis â†’ Scenario Manager. ï‚·Proceed to create at least three Scenarios with different data for the Changing Cells (the 3 cells on the D column with the hypothetical scores for the parts of the Final Exam). ï‚·The Result Cell when closing the Scenario Manager â€“ by clicking on the Summary button â€“ is D30. n) After generating the Scenario Summary, save your work by using the File â†’ Save As option and submit your file to Canvas â†’ CS170 â†’ Assignments â†’ RecitationProject.
