5. PivotTable
The PivotTable report summarizes the way large amounts of data rapidly interactive. Use a PivotTable report to analyze in detail the digital data and answer unexpected questions about the data.
Create a PivotTable report, you must define the data source and reposition him in the workbook and planning fields.

Column labels: A field that has a column orientation in the pivot table.
Grand totals: A row or column that displays totals for all cells in a row or column in a pivot table.
Group: A collection of items treated as a single item.
Item: An element in a field that appears as a row or column header in a pivot table.

Source data: The data used to create a pivot table.
Subtotals: A row or column that displays subtotals for detail cells in a row or column in a pivot table.
Table Filter: A field that has a page orientation in the pivot table
Values area: The cells in a pivot table that contain the summary data.

7. PivotTable report is designed specifically for:
querying large amounts of data in several ways easy to use.
the total sub-account of digital data and the data collected and summarized by categories and sub-categories and create custom calculations and formulas.
transfer of rows to columns or columns to rows (or "modification") to display different summaries of the data source.
Sub-Group of filtering the most useful data and striking and sorted, assembled and coordination of this policeman to let you focus on the information you want.
provide explanatory comments on your computer or printed attractive brief reports.

11. Delete PivotTable report.
Click anywhere in PivotTable you want to delete.
Press DELETE.

12. What-If Analysis, in Reverse
What-If Analysis : What-If Analysis in Excel allows you to try out different values (scenarios) for formulas.

13. What-If Analysis, in Reverse …cont
What-If Analysis: in this example we want to change the total as we change the prices ,,,
As we don't have to write the prices every time , just we write them once.
From the Data Tap, click on What-if analysis.
Then Click “Scenario Manager”

14. Analyzing Data Using Goal Seeking and Solver

15. Introducing Solver
Goal Seek: Determines the value that you need to enter in a single input cell to produce a result
Solver: Determines the values that you need to enter in multiple input cells to produce a result

16. Introducing Solver…Cont
Load the Solver Add-in
To load the solver add-in, execute the following steps.
1. On the green File tab, click Options.
2. Under Add-ins, select Solver Add-in and click on the Go button.
3. Check Solver Add-in and click OK
4. You can find the Solver on the Data tab.

17. What Is Solver In Excel
Introducing Solver

18. Appropriate problems for Solver
To understand the Solver, it’s important to understand the basic concept of what it does and how it works. There are 3 primary components you should be familiar with.
Target Cell. This is the cell that represents the goal or objective of the problem. In our example, we will be attempting to have a schedule that has no shortfall in staffing. The cell that reports any shortfall will be our Target Cell.
Variable Cells are the cells that can be modified to arrive at the desired outcome. In our example, that will be work hours from Monday through Friday for all employees.
Constraints. This are restrictions or limitations to what Solver can do to solve the problem. For example, if Employee X cannot work Tuesdays, Solver is restricted from assigning an employee work on Tuesdays.

19. A simple Solver example 1/2
Here we have solver example , about electoral devices factory and optimize the production profit the factory has a limited resouces and three lines of product. Excel solver will help to tell us what to produce more of the products to get more profit.

20. A simple Solver example 2/2

21. Solver Examples Here are some solver examples :
Solving simultaneous linear equations
Minimizing shipping costs
Allocating resources
Optimizing an investment portfolio
