SESSION 1: Analyze data using SCENARIOS AND GOAL SEEK

Data Consolidation allows you to gather together your data from separate worksheets into a master worksheet. In other words, the Data Consolidation function takes data from a series of worksheets and summaries it into a single worksheet.

STEPS for Data Consolidation are :

1) Open the worksheet that contains the cell ranges to be consolidated.

2) Choose the Consolidate option under the Data menu.

3) Select Source data range and click Add. The selected range now appears on the Consolidation ranges list.

4) Select additional ranges and click Add after each selection.

5) Specify where you want to display the result by selecting a target range from the Copy results to box.

6) Select a function from the Function list. The Sum function is the default setting.

7) Select either Row labels or Column labels. The text in the labels must be identical in all the specified Source range.

8) Click OK to consolidate the ranges.

NOTE : Use Data > Define Range to give name to a range

Creating Subtotals :

SUBTOTAL, totals/adds data arranged in an array—that is, a group of cells with labels for columns and/or rows. Using the Subtotals dialog, you can select arrays, and then choose a statistical function to apply to them. It is accessible from Data menu.

Steps to insert subtotal values into a sheet:

1) Ensure that the columns have labels.

2) In the Subtotals dialog , in the Group by box, select the column that you want to add the subtotals to.

3) In the Calculate subtotals for box, select the columns that you want to subtotal.

4) In the Use function box, select the function.

5) Click OK.

Using “What If” Scenarios :

Scenarios are a tool to test “what-if” questions. Each scenario is named, and can be edited and formatted separately. You can easily switch between different scenarios by using the Navigator. For example, if you wanted to calculate the effect of different interest rates on an investment, you could add a scenario for each interest rate, and quickly view the results.

Creating Scenarios :

1) Select the cells that contain the values that will change between scenarios.

2) Choose Tools > Scenarios.

3) On the Create Scenario dialog , enter a name for the new scenario. This name is displayed in the Navigator and on the title bar of the scenario.

4) Optionally add some information to the Comment box.

5) Optionally select or deselect the options in the Settings section.

6) Click OK to close the dialog

NOTE : You can create several scenarios for any given range of cells

Goal Seek

Usually, you run a formula to calculate a result based upon existing values. By contrast Goal Seek option under Tools menu, helps to find values which will produce the result that you want. for example

Chief Financial Officer has a good idea of the company’s income in the first three quarters, because of the contracts that are already signed. For the fourth quarter, however, no definite income is available. So how much must the company earn in Q4 to reach its goal? Then Chief Financial Officer runs a goal seek on the empty cell for Q4 sales and receives the answer

Solver :

Solver option under Tools menu amounts to a more elaborate form of Goal Seek. The difference is that the Solver deals with equations with multiple unknown variables. It is specifically designed to minimize or maximize the result according to a set of rules that you define.

Session 2 : Link Data and Spreadsheets Using Multiple Workbooks and Linking Cells

Spreadsheet allows you to link the cells from various worksheets to summarize data from several sources. In this manner, you can create formulas using a combination of local and linked information. Multiple sheets help to keep the information organized.

Inserting New Sheets

When you open a new spreadsheet, by default, it has a sheet named Sheet1. There are several ways to insert a new sheet. The first step, in all cases, is to select the sheet that will be next to the new sheet. Then do any of the following:

  1. Select Insert > Sheet from the menu bar, or
  2. Right-click on the tab and select Insert Sheet, or
  3. Click in an empty space at the end of the line of sheet tabs.

Each method opens the Insert Sheet dialog box where you can choose to put the new sheet before or after the selected sheet and how many sheets to insert.

Renaming Sheets

There are three ways you can rename a worksheet. You can do any of the following:

  1. Double-click on one of the existing worksheet names.
  2. Right-click on an existing worksheet name, then choose Rename from the resulting Context menu.
  3. Select the worksheet you want to rename (click on the worksheet tab) and then select the Sheet option from the Format menu. This displays a submenu from which you should select the Rename option.

Cell Reference : A cell reference refers to a cell or a range of cells on a worksheet that can be used in a formula to calculate values.

Referencing Other Sheets

There are two ways to reference cells in other sheets :

1) By entering the formula directly using the keyboard. :

Typing the reference is simple once you know the format the reference takes. The reference has three parts to it: Path and file name . Sheet name . Cell name
The general format for the reference is =’file:///Path &File Name’#$SheetName.CellName

2) By using the mouse.

Hyperlinks : Hyperlinks can be used in Calc to jump to a different location from within a spreadsheet to other parts of the same file or to different files or even to web sites.

Hyperlinks can be stored within your file as either relative or absolute

An absolute link will stop working only if the target is moved. A relative link will stop working only if the start and target locations change relative to each other. For instance, if you have two spreadsheets in the same folder linked to each other and you move the entire folder to a new location, a relative hyperlink will not break.

You can insert and modify links using the Hyperlink dialog. To display the dialog, click the Hyperlink icon on the Standard toolbar or choose Insert > Hyperlink from the menu bar.

Linking To External Data :

You can insert tables from HTML documents, and data located within named ranges from an OpenOffice.org Calc or Microsoft Excel spreadsheet, into a Calc spreadsheet You can do this in two ways: using the External Data dialog or using the Navigator

Using the External Data dialog : Steps are

  1. Open the Calc worksheet where the external data is to be inserted. This is the target worksheet.
  2. Select the cell where the upper left-hand cell of the external data is to be inserted.
  3. Choose Insert -> Link to External Data.
  4. On the External Data dialog, type the URL of the source worksheet
  5. In the Available tables/range list, select the named ranges or tables you want to insert.
  6. Click OK to close this dialog and insert the linked data.

Linking To Registered Data Sources :

You can access a variety of databases and other data sources and link them into Calc worksheets. First you need to register the data source with OpenOffice.org. To register a data source that is in *.odb format:

  1. Choose Tools -> Options -> OpenOffice.org Base -> Databases.
  2. Click the New button to open the Create Database Link dialog.
  3. Enter the location of the database file, or click Browse to open a file browser and select the database file.
  4. Type a name to use as the registered name for the database and click OK.

SESSION 3: SHARING WORKSHEET DATA

Spreadsheet software allows the user to share the workbook and place it in the network location where several users can access it simultaneously. This is required to either speed up data entry or simply make things easier for collaboration purposes.

Setting Up A Spreadsheet For Sharing :

Open the spreadsheet document , choose Tools > Share Document to activate the collaboration features for this worksheet. A dialog opens where you can choose to enable or disable sharing.

Spreadsheet Class 10 Notes

To enable sharing, select the box at the top of the dialog, and then click OK. A message appears stating that you must save the worksheet to activate shared mode. Click Yes to continue. The word (shared) is then shown on the title bar after the worksheet’s title.

Saving A Shared Spreadsheet :

When you save a shared spreadsheet, one of several situations may occur:

  • If the worksheet was not modified and saved by another user since you opened it, the worksheet is saved.
  • If the worksheet was modified and saved by another user since you opened it, one of the following events will occur:
    1. If the changes do not conflict, the worksheet is saved, the dialog below appears, and any cells modified by the other user are shown with a red border.
    2. If the changes conflict, the Resolve Conflicts dialog is shown. You must decide for each conflict which version to keep, yours or the other person’s. When all conflicts are resolved, the worksheet is saved.
    3. If another user is trying to save the shared worksheet and resolve conflicts, you see a message that the shared spreadsheet file is locked due to a merge-in in progress.

Note: Most spreadsheets software automatically turns off some features in shared workbooks to simplify the workbook since multiple people can be working on the file at the same time. For example, shared workbooks don‘t allow merging cells, conditional formatting, or inserting pictures/graphs/etc

Record Changes :

Calc has the feature to track what data was changed, when the change was made, who made the change and in which cell the change has occurred. for example

If you are the sponsor of a youth baseball team. The coach has submitted a budget to you and you are concerned that the coach won’t see the changes you made, So you decided to use Calc with the record changes feature turned on, so that the coach can easily see the changes you have made.

How to turned on Record Changes feature ON :

  1. Open the Shared Spreadsheet.
  2. Select Edit > Changes > Record from the menu bar.
  3. Begin editing the worksheet.

NOTE : A red colored border, with a dot in the upper left-hand corner, appears around a cell where changes were made.

Viewing Changes :

Calc allows you to control what changes you see when reviewing a worksheet. To change the available filters, select Edit > Changes > Show You can filter based on:
