Roadmap

Using Data Tables and Excel Scenarios for What-If Analysis

• Chapter 8

Chapter Objectives

Conducting Break-Even and Sensitivity Analyses

• Break-even analysis– Type of what-if analysis that concentrates on an

activity at or around the point at which a product breaks even

• Sensitivity analysis– Type of what-if analysis that attempts to examine

how sensitive the results of an analysis are to changes in the assumptions

Analyzing What-If Results with Data Tables

• Data table– Range of cells containing values and formulas– Change the values, the results change– Can compare results of many calculations; useful

for break-even and sensitivity analyses

Types of Data Tables

One-variable data tables Two-variable data tables

• One input cell and many result cells

• Set of input values must be arranged perpendicular to the set of output formulas, with no value or formula located at the intersection of the set of input values and output formulas

• Two input cells, only one result cell; determines how two values affect a single result

• The two sets of input values must be set up perpendicular to each other, and the output formula must be in the cell at the intersection of the two sets of input values

Succeeding in Business with Microsoft Excel 2010 11Level 1 home

Preparing a Worksheet for Data Tables

• Data table depends on values and formulas used in a worksheet and must appear on the same worksheet that contains this data

• Worksheet must:– Use input cells that contain values you want to

modify in a what-if analysis– Use result cells containing formulas that calculate

the values you want to analyze

Varying One Valuein a What-If Analysis

1. Set up the structure for the data table– Create a set of input values you want to use in a

what-if analysis– Indicate the results you want to see in the data

table

2. Instruct Excel about how the data table’s structure relates to the input section of the worksheet

Completing a One-VariableData Table

• Select the range that includes the input and results cells

• Specify whether input cells are arranged in column or row (Table dialog box)

Comparing the Results of Complex Analyses

• Excel Scenario Manager– Perform what-if analysis with more than two input

cells– Define and save sets of values as scenarios; view and

change them to produce and compare different results• Requirements for running a scenario

– Well-structured input and output sections– Output depends on input through use of formulas– Changing cells and results cells must be on same

worksheet; cannot span worksheets

Planning Scenarios

• Prepare the inputs• Prepare the outputs• Set up a scenario• Prepare a worksheet for scenarios

SUMPRODUCT function can be used to sum a series of products (the results of a multiplication task)

Setting up a Scenario

Succeeding in Business with Microsoft Excel 2010 31Level 2 home

Preparing a Worksheet for Scenarios

• Determine the changing cells in the worksheet• Name the input and result cells you want to

use

Succeeding in Business with Microsoft Excel 2010 32Level 2 home

Adding Scenarios to a Worksheet

• Use Add Scenario dialog box in Scenario Manager– Each scenario must have a name

• Indicate scenario’s changing cells in Changing cells box

• Enter specific assumptions for changing cells in the Scenario Values dialog box

Succeeding in Business with Microsoft Excel 2010 33Level 2 home

Scenario Manager Dialog Box

Succeeding in Business with Microsoft Excel 2010 34Level 2 home

Working with Scenarios

• Viewing and Analyzing Scenarios– Click the scenario name in the Scenario Manager

dialog box– Click the Show button – Compare different scenarios

• Editing and Deleting Scenarios– Use the Scenario Manager dialog box

Succeeding in Business with Microsoft Excel 2010 35Level 2 home

Generating Scenario Reports

• Use Scenario Manager to create two types of scenario reports– Scenario summary– Scenario PivotTable

• Before printing a report, indicate which result cells are of interest

Succeeding in Business with Microsoft Excel 2010 36Level 2 home

Creating Scenario Summaries

• Shows values for all changing cells and for all indicated result cells for all scenarios in the worksheet

• Tabular format makes it easy to compare results

Succeeding in Business with Microsoft Excel 2010 37Level 2 home

Creating Scenario PivotTable Reports

• Summarize result cells from a scenario• Can change the view of the data to see more

or fewer details• Can edit and format the report

Understanding Simulation in Business

• Simulated results– Based on realistic, but not actual, data

• Excel functions for comparing simulated results– RAND– VLOOKUP– Can also create a two-variable data table that

contains probable data and generates simulated results

Developing a Simulation with a Two-Variable Data Table

• Structuring a two-variable data table for a simulation– One set of input values must be a sequence of numbers

that represent the number of iterations of the simulation• Completing a two-variable data table for a

simulation– Highlight entire table range and tell Excel to which input

cells the sets of input values relate– Iteration values are directed to any empty cell in the

worksheet

Calculating Simulation Statistics

• Calculate some statistics about the data; base the analysis on those statistics, not the raw data itself

Succeeding in Business with Microsoft Excel 2010 46Level 3 home

Interpreting Simulation Results

• Can quantify differences in prices and allow you to make more informed decisions

• Can be facilitated using a method of aggregating the data, such as statistics functions
