WHAT-IF ANALYSIS 3 important tools which enable to perform what-if analysis Enables you to see how changes in variables affect calculated results A variable is a value that can be changed or to see how those changes impact other values An independent variable is one that can be controlled directly, such as the price of an item A dependent variable is one that may vary such as the number of items sold
CREATE A ONE-VARIABLE DATA TABLE A one-variable data table is a dataanalysis tool that provides various results based on changing one variable Two important elements: Input cells contain values to be modified for what-if analysis Result cells contain values to be modified
EXAMPLE Calculate the Payment Amount using PMT function And calculate total payment=b6*b4 Total interest is =B7-B1
CREATE A ONE-VARIABLE DATA TABLE In C12 type =B6 In D12 type =B7 In E12 type =B8 In cell B13 and B14 type.06 and.065 AutoFill cells through B17 Format cells B13:B17 as percentage with 2 decimal places
CREATE A ONE-VARIABLE DATA TABLE(CONTD) Create a data table by selecting cells B12:E17 Select column input as cell B2 Now table shows how changes in the interest rate for loan affect the monthly payment, total payments and total interest
TWO VARIABLE DATA TABLE Similar to a one variable data table Can manipulate two different variables. Interest rate changes and the loan amount of the car changes.
CREATE A TWO-VARIABLE DATA TABLE In cell H11 type =B6 In cell H12 and H13 type.06 and.065 Now autofill cells through H16 Format cells H12:H16 as Percentage with 2 decimal places In cell I11 and J11 type 20000 and 25000
CREATE A TWO-VARIABLE DATA TABLE Select cells H11:J16 and insert a data table Column input cell:b2 Row input cell:b1 Now this table shows how changes in the interest rate and the loan amount affect the monthly payment.
GOAL SEEK Is a method of finding the solution to problems Can I afford this Enables you to work backwards to solve a problem Set the end result to determine the input to produce the result.
GOAL SEEK( CONTD.) Example: Want to buy a car, thinking of a monthly payment of $200 Goal seek is used to determine the most you can borrow to keep that monthly payment. Set Cell-cell to be optimized To Value-result you want to achieve By Changing Cell-value of variable to be adjusted
SCENARIO MANAGER Scenario Manager is designed to work with several sets of assumptions called as scenarios. These enable to quickly compare the results of multiple scenarios. Each scenario represents different sets of what if conditions to be considered in assessing the outcome of the spreadsheet models
SCENARIOS We could present our results as a Summary if we wanted to. Click on Data What if Analysis Scenario Manager Click Summary 14
GROUPING AND UNGROUPING WORKSHEETS All worksheets Adjacent worksheets use SHIFT Non Adjacent worksheets use CTRL 15
WORKSHEET REFERENCE Pointer to a cell in another worksheet Syntax : Worksheet_name!Range_Of_Cells 16
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) 17
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. 18
TEMPLATES, THEMES AND STYLES 19
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 20
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 21
