# Mastering Data Tables in Excel: Perform Sensitivity Analysis and Scenario Modeling

In this tutorial, we will explore the powerful feature of data tables in Excel. Data tables provide a convenient way to analyze sensitivity and create scenarios by changing input values and observing the impact on calculated results. Effective data analysis using tables enhances financial models, project feasibility, and business scenario evaluation.

### Section 1: Understanding Data Tables

Excel data tables are a powerful tool that can help perform sensitivity analysis and scenario modeling to analyze different outcomes based on varying input values. Sensitivity analysis in Excel is also known as “data tables” and can be accessed in the ribbon menu under the Data tab and “What-If Analysis.

Here are some benefits of using data tables for sensitivity analysis:

1. Varying assumptions: Data tables allow users to vary assumptions or drivers in a model and look at the output under various outcomes.
2. Analyzing different outcomes: Data tables allow users to analyze different outcomes based on varying input values, making it easier to understand how changes in input values affect the output.
3. Saving time: Data tables provide a shortcut for calculating multiple versions in one operation and a way to view and compare the results of all variations on the worksheet.

To perform sensitivity analysis using data tables in Excel, users can follow these steps:

1. Enter the input values in a column or row in the worksheet.
2. Enter the formula that calculates the output based on the input values.
3. Select the input values and the formula.
4. Go to the Data tab, select “What-If Analysis, ” then “Data Table”.
5. In the “Data Table” dialog box, enter the cell reference for the input value and click OK.

Data tables are a powerful tool that can help perform sensitivity analysis and scenario modeling to analyze different outcomes based on varying input values. Data tables allow users to save time, analyze different outcomes, and better understand how input value changes affect the output.

### Section 2: Creating a One-Variable Data Table

Creating a one-variable data table in Excel can help users examine the impact of changing a single input variable on calculated results. Here are the steps to create a one-variable data table:

1. Enter the input values in a column or row in the worksheet.
2. Enter the formula that calculates the output based on the input values.
3. Select the input values and the formula.
4. Go to the Data tab, select “What-If Analysis, ” then “Data Table”.
5. In the “Data Table” dialog box, enter the cell reference for the input value in the “Column Input Cell” field.
6. Click OK.

Once the data table is created, users can examine the impact of changing the input value on the calculated results. The results will be displayed in a table format, with the input values in the left column and the calculated results in the right column.

To ensure accurate and meaningful data analysis, users should ensure that the input values and results are incorrectly formatted cells and contain the appropriate data types. For example, if the input values are dates, they should be formatted as dates, and if the calculated results are currency values, they should be formatted as currency.

Creating a one-variable data table in Excel can help users examine the impact of changing a single input variable on calculated results. Users can perform accurate and meaningful data analysis by ensuring that the input values and results are incorrectly formatted cells.

### Section 3: Creating a Two-Variable Data Table

A two-variable data table in Excel is a tool that allows users to analyze the combined impact of two variables on the calculated results. This type of data table is useful when users want to see how the final result changes when two input variables change simultaneously.

Here are the steps to create a two-variable data table in Excel:

1. Enter the input values for the two variables in a column and row in the worksheet.
2. Enter the formula that calculates the output based on the input values.
3. Select the input values and the formula.
4. Go to the Data tab, select “What-If Analysis, ” then “Data Table”.
5. In the “Data Table” dialog box, enter the cell reference for the input value in the “Row Input Cell” field and the cell reference for the other input value in the “Column Input Cell” field.
6. Click OK.

Once the data table is created, users can examine the impact of changing the two input values on the calculated results. The results will be displayed in a table format, with the input values in the left column and top row and the calculated results in the remaining cells.

To ensure accurate and meaningful data analysis, users should ensure that the input values and results are incorrectly formatted cells and contain the appropriate data types. Using a two-variable data table in Excel allows users to analyze the combined impact of two variables on the calculated results, making it easier to understand how changes in input values affect the output.
