Instructions:

Grades spreadsheet

1. Go to Sakai → CS170 Gradebook page and do the following:

a. Select the Gradebook Items, Grades, Due

Dates and Comments columns. Do not select the column headings, only

the items and their information.

b. Copy the selection by right-clicking on it and choosing the option Copy.

c. Start Excel, create a Blank worksheet.

d. Select the cell C3 on the worksheet and paste the information copied.

Widen the C column width.

▪

Rename the worksheet as Grades.

e. Delete column E: click on the E letter that identifies that column and then

right -click and select Delete (this is needed since that column came with

Data format).

f.

Add the following entries to the list of activities on the C column (below

the last activity listed): Final Exam Part 1, Final Exam Part 2and Final

Exam Part 3.

g. Starting on the cell E3, type the maximum number of points possible for

each Gradebook Item:

▪

2 points for Assignment 1

▪

20 points for the other Assignments and the Recitation Project

▪

80 points each for Exams 1 and 2

▪

120 for the Final Exam (simply ignore it if this entry is not listed

yet)

▪

Note: If there is an item for which you do not have a grade yet, do

not enter the maximum points for it.

h. On row 28 do the following:

▪

Enter the label “Totals” on C28

▪

The total points obtained will be calculated on D28. Since there

might be some blank cells, an appropriate function for this cell is

SUMIF.

▪

Arguments for SUMIF:

▪

range: the list of scores on the D column

(including blank cells for the activities with no

scores yet)

▪

criteria: greater than or equal to 0 (express this

using Excel notation)

▪

sum_range: the list of scores on the D column

(including blank cells for the activities with no

scores yet)

▪

i.

Copy the function from D28 to E28 using the fill handle.

On row 29:

▪

Enter the label “Performance” on C29.

▪

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).

▪

j.

Format your performance with Percentage style with 1 decimal.

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.)

0%

F

60%

D

70%

C

76%

C+

80%

B

87%

B+

90%

A

k. On row 30:

o

Enter the label Letter Grade on C30.

o

On D30 insert the VLOOKUP function to calculate the current letter grade

based on your Performance % and the Grading table created on G3:H9.

▪

The arguments for the VLOOKUP function are:

▪

lookup_value: your numeric performance % (from D29).

▪

table_array: the table that converts percentages into letter

grades which you created starting on G3.

▪

col_index_num: 2 (since the second column contains the

letter grades).

l.

What-If Analysis:

o

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.

o

The formula entered on cell D28 which currently contains SUMIF needs

to be modified to process the hypothetical Final Exam scores for each of

its parts.

o

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(…)

o

▪

The first IF that needs to be added – use the Formula bar to add it

– will have the following arguments (use Excel

notation; value_if_false does not need an entry):

▪

Logical_test: 2 x Score of Final Exam Part 1 > Score of

Exam 1

▪

Value_if_true: (2 x Score of Final Exam Part 1) – Score of

Exam 1

▪

Value_if false:

At this point D28 should have the following format:

=SUMIF(…) + IF(…)

•

The second IF that needs to be added will have the following arguments

(use Excel notation; value_if_false does not need an entry):

o

Logical_test: 2 x Score of Final Exam Part 2 > Score of Exam 2

o

Value_if_true: (2 x Score of Final Exam Part 2) – Score of Exam 2

o

Value_if false:

At this point D28 should have the following format:

=SUMIF(…) + IF(…) + IF(…)

a. 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.

o

On the D column of those rows place some hypothetical numbers

(Example: 32 on each of those three cells).

o

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.

b. At this point, the What-If Analysis may start. Click on D30, then on the Data

tab → What-If Analysis → Scenario Manager.

o

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).

o

The Result Cell when closing the Scenario Manager – by clicking

the Summary button – is D30.

c. After generating the Scenario Summary, save your work and submit it

to Sakai → Test and Quizzes section.
