WHAT – IF ANALYSIS Data Table Goal Seek Scenario Manager 3

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. 4

DATA TABLE One variable Data Table Two variable Data Table 5

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 6

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. 7

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 8

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. 9

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 10

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 11

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 12

GOAL SEEK 13

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 14

SCENARIO MANAGER 15

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. 16

USING SCENARIO MANAGER Create and edit Scenarios View Scenarios Generate Scenario Summary Report 17

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 18

CREATE A SUMMARY REPORT What-If Analysis  Scenario manager  Summary Result cells box : Range B12:B14 Click OK 19

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. 20

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 22

SOLVER EXAMPLE Step 1: Set the Objective and Variable cells Step 2: Define Constraints Step 3: Generate a report 23

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 24

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 25

STEP 3… Generate a report. –Click on SOLVE –Select ANSWER in the REPORT LIST –Observe the result in Answer Report 1 worksheet tab. 26

MULTIPLE-SHEET WORKBOOK MANAGEMENT 27

GROUPING AND UNGROUPING WORKSHEETS All worksheets Adjacent worksheets use SHIFT Non Adjacent worksheets use CONTROL 28

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 29

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) 30

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. 31

TEMPLATES, THEMES AND STYLES 32

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 33

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 34

APPLYING CELL STYLES A cell style is a set of formatting options applied to worksheet cells Home ribbon Styles -> Cell styles 35
