# How to configure and use the Excel forecasting system | Productivity

Microsoft Excel is a spreadsheet editor with powerful features for comparing data. The program also has a sophisticated system of logical analysis and forecasts that facilitates calculations and estimates with mathematical operations.

To use these tools, the user must access commands from the Data tab and configure certain characteristics of the spreadsheets. Check out in this tutorial how to use the features of the Excel forecasting system.

Seven Excel functions that few people know

## Hypothesis Testing: Achieving Goals

Step 1. The Achieve Goals feature causes Excel to estimate a value according to the estimated goal for a formula. In the highlighted example, the goal is to know how much to spend on books to not exceed a budget. To use this tool, on the Data tab, select the Hypothesis Test button and choose Achieve Goals;

Step 2. Then, select the Define cell field and choose the cell with the sum formula in its table. In this case, there must be a sum in the spreadsheet for the resource to work;

Step 1. To use the Forecast Worksheet feature, you need to use a number sequence in the main columns name line. In the example below, the months have been transformed into their respective numbers;

Step 2. Then, select the entire table you want to turn into a Forecast Sheet and, on the Data tab, click on the resource button highlighted in the image in the upper right corner;

## Hypothesis Testing: Data Table Function

Step 1. The Data Table allows you to create an estimate by multiplying and adding two or more values. The following example seeks to know the total sale with new values ​​for the prices of two products;

Step 2. For the feature to work, I need one of the estimates to be in a row sequence, while the other one is in a row sequence, as in the image below. The total of the mathematical operations that will be calculated must be at the meeting between the sequences, as indicated by the arrow in the image;

Step 3. Then, select the table with the indicated strings and, on the Data tab, select Hypothesis Test and then the Data Table option …;

Step 4. In the fields of the resource window, enter the original values ​​that were operationalized in mathematical accounts, indicating what is in the sequence of lines and the other in the column. In the example, the values ​​of the products in the previous month were chosen – including, the number of items sold the total value previously indicated;

Step 5. After confirming in Ok, the table will be assembled indicating the total in each value estimate defined by the original rows and columns;
