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

Copy the function from D28 to E28 using the fill handle.
On row 29:
?
Enter the label Performance on C29.

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

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

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.
