ANNOUNCEMENTS

• Homework # 3 is due on 09/27/2013 by 11.59pm

3

WHAT – IF ANALYSIS

• Data Table• Goal Seek• Scenario Manager

4

WHAT-IF ANALYSIS

• What if analysis is the process of changing variables to observe how changes effects calculated results.

• A variable is an input value that can change to other values to affect the results of a situation.

5

DATA TABLE

• One variable Data Table• Two variable Data Table

6

CREATING A ONE VARIABLE DATA TABLE

• A data analysis tool that provides various results based on changing one variable.

• 3 steps– Enter Substitution values for a one-variable

data table– Enter formulas and complete the data table– Format the one-variable data table

7

SUBSTITUTION VALUES…

• Click cell D4, enter 4% • Home ribbon -> Editing group -> Fill ->

Series• Select column radio button, and give Step

value box value as 0.25% and Stop value box value as 6%

• Format the range D4:D12 to percentages with 2 decimal points.

8

COMPLETING THE DATA TABLE…

• E3->B12 : F3->B13 : G3->B14• Select D3:G12• Under DATA TAB go to What-If Analysis ->

Data table• Give column input cell as $B$4 and click

OK

9

FORMAT THE TABLE…

• Select range E4:G12 and give the number format as Accounting with 2 decimal points

• Enter APR in cell D3• Select cell E3 Format cells Select

Custom General type “Payment” and click OK.

• F3 as Total Repaid and G3 as Total Interest.

10

CREATING A TWO VARIABLE DATA TABLE

• A data analysis tool that provides various results based on changing two variables.

• 2 steps– Set up the structure for a Two-Variable data table– Complete the Two-Variable Data Table

11

DATA TABLE STRUCTURE…

• Different “cost of car” in row J3:L3– Enter 20000,25000,30000

• Different APR in column I4:I20– Increasing values from 4% to 6% at a step value

od 0.125%– Format I4:I20 as Percent style with 3 decimal

points

• Specify which variation do you want to observe (eg. Monthly Payment B12) in cell I3

12

COMPLETING THE TABLE...

• Select I3:L20• Under DATA TAB go to What-If Analysis ->

Data table• Give B2 as row input cell box and B4 as

column input cell box.• Format cell I3 to display APR

13

GOAL SEEK

14

CREATE A GOAL SEEK

• Goal seek is a tool that identifies the necessary input value to obtain a desired goal.

• What If Analysis ->Goal seek• Set cell box B12• Enter 300 in To Value box• By changing cell box B2• Click OK to accept the solution

15

SCENARIO MANAGER

16

SCENARIO MANAGER

• Scenario is a set of values that represent a possible situation.

• Scenario manager enables you to define and manage scenarios to compare how they affect results.

17

USING SCENARIO MANAGER

• Create and edit Scenarios• View Scenarios • Generate Scenario Summary Report

18

CREATE A SCENARIO

• What-If Analysis -> Scenario manager• Click Add• Scenario name : Best-case• Changings cell : B2:B5• Enter : 25000 in $B$2 , 5000 in $B$3, 0 in $B$4, 6 in $B$5• Create Additional Scenarios• Click Add• Scenario name : Most Likely-case• Changings cell : B2:B5• Enter : 22500 in $B$2, 6500 in $B$3, 4.25% in $B$4, 5 in

$B$5

19

CREATE A SUMMARY REPORT

• What-If Analysis Scenario manager Summary

• Result cells box : Range B12:B14• Click OK

20

SOLVER

• Solver is an add-in application that manipulates variables based on constraints to find the optimal solution to a problem.

• Solver is one of the most sophisticated what-if analysis tools, and people use Solver in a variety of situations and industries.

21

LOADING THE SOLVER ADD-IN

• Go to file tab• Select options Add-ins• Manage->Excel Add-ins and click GO• Select Solver Add-in• You can see Solver option in Data ribbon

22

OPTIMIZING RESULTS WITH SOLVER

• Identify Objective cell, contains the formula-based value that you want to maximize, minimize. Or set to a value in Solver.

• Identify Changing cells, contains a variable whose value changes until Solver optimizes the value in the objective cell

23

SOLVER EXAMPLE

• Step 1: Set the Objective and Variable cells

• Step 2: Define Constraints• Step 3: Generate a report

24

STEP 1…

• Enter 25000 in B2 and 5000 in B3• Define objective cell and changing variable

cells. – Objective cell -> B12– To value off : 300– By changing variable cells : B2:B5

25

STEP 2…

• Define constraints – B2<=30,000– B2>=20,000– B3<=7,500– B3>=5,000– B4<=6%– B4>=4%– B5<=6– B5=integer– B5>=4

26

STEP 3…

• Generate a report.– Click on SOLVE– Select ANSWER in the REPORT LIST– Observe the result in Answer Report 1

worksheet tab.

27

MULTIPLE-SHEET WORKBOOK MANAGEMENT

28

GROUPING AND UNGROUPING WORKSHEETS

• All worksheets• Adjacent worksheets use SHIFT• Non Adjacent worksheets use CONTROL

29

WORKSHEET REFERENCE

• Pointer to a cell in another worksheet• Syntax : ‘Worksheet_name’!

Range_Of_Cells• Select cell B1 in sheet 1 and calculate the

average for cells J4:J20

30

3D FORMULA

• Formula or function that refers to the same range in multiple worksheets.

• Select cell B2 in sheet 1• Type =SUM(• Click sheet 2, press and hold shift and

then click sheet 3 and select cell A1• The formula becomes

=SUM(Sheet2:Sheet3!A1)

31

INSERTING HYPERLINKS

• Hyperlink is an electronic marker to another location in a worksheet, workbook, file, web page or email.

• Select B1 Insert ribbon Hyperlink in the Links group

• Type J4:J20 in the Type the cell reference box and click OK.

32

TEMPLATES, THEMES AND STYLES

33

SELECTING A TEMPLATE

• Template is a special workbook file used as a model to create similarly structured workbooks

• File -> New• Search for template• Select one• Preview of selected template

34

APPLYING THEMES AND BACKGROUNDS

• A theme is a collection of colors, fonts, and special effects.

• Page Layout ribbon • Themes • Select one• A background is an image that appears

behind the worksheet data onscreen• Page Layout ribbon• Background -> select desired file

35

APPLYING CELL STYLES

• A cell style is a set of formatting options applied to worksheet cells

• Home ribbon• Styles -> Cell styles
