Sensitivity analysis is a very important technique in Excel that allows you to evaluate the impact of different variables on a model. It is useful for understanding how changes to certain parameters affect the final result of a worksheet.
There are different types of sensitivity analysis, but one of the most common is what-if analysis. In this case, the user sets a series of values for one or more variables and evaluates how these changes affect the final result of the worksheet.
To perform what-if analysis in Excel, you need to follow a few simple steps:
- Define the variables to be analyzed;
- Define the values for each of the variables;
- Configure worksheet formulas so that they use the defined variables;
- Evaluate the results for each of the defined values.
One of the most useful tools for performing sensitivity analysis in Excel is the data table. This table allows the user to define different values for one or more variables and visualize the corresponding results.
