2. This lesson includes the following sections: • Spreadsheet Programs and Their Uses • The Spreadsheet's Interface • Entering Data in a Worksheet • Editing and Formatting a Worksheet • Adding Charts • Analyzing Data in a Spreadsheet

3. Spreadsheet Programs and Their Uses • Spreadsheets provide tools for working with numerical data. • You can use a spreadsheet program to create budgets, balance sheets, and other types of number- based documents. • You can display your information in a traditional row-and-column format, or in a chart.

4. Report using color and graphics Classic row and column format

5. The Spreadsheet's Interface • In a spreadsheet program, you work in a document called a worksheet. You can collect multiple worksheets into a file called a workbook. • Most Windows-based word spreadsheets offer a similar set of tools, including a formula bar, where you can enter and edit data. • Data is displayed in cells. A cell is the intersection of a row and column. • Each cell has a cell address – the combination of the cell's column letter and row number.

6. Cell Menu bar Tool bars Formula bar Row Column Scroll boxes Status bar

7. Entering Data in a Worksheet - Types of Data You enter four types of data in a worksheet's cells: • Labels--text or numbers not used in calculations. • Values--numbers that can be used in calculations. • Dates--a necessary part of most worksheets. • Formulas--commands to perform calculations based on numbers or formulas.

8. Entering Data in a Worksheet - Formulas and Functions • If a formula uses a value in another cell, the formula contains a cell reference, or the address of the referred cell. • Formulas can refer to entire ranges (or blocks) of contiguous cells as well as individual cells. • A function is a predefined formula, which the spreadsheet provides to perform a specific type of calculation. You provide arguments that tell the function what data to use.

9. Editing and Formatting a Worksheet • Spreadsheets provide many of the same editing and formatting tools found in word processors. • You can change, copy, move, and delete the data in any cell.

10. Relative and Absolute Cell References • If a formula uses a relative cell reference, it automatically dates if (copied or moved), to a different place. • An absolute cell reference always refers to the same cell even if the formula is moved to a different place.

11. Adding Charts • A chart is a graphical representation of the data in a worksheet. • Spreadsheets provide tools that make it easy to create a chart from worksheet data. • You can use many different types of charts, and apply many effects to a chart, to present your data in the most appropriate way.

13. Analyzing Data in a Spreadsheet Three commonly used data-analysis tools are: • What-if analysis, which lets you test scenarios to see how each affects the result. • Goal seeking, which finds values that make the result meet your specifications. • Sorting, which lets you arrange the worksheet's data in various ways.

14. lesson 14 review • Define and differentiate the terms worksheet and spreadsheet. • Identify four types of data that can be entered in a worksheet. • Explain how cell addresses are used in spreadsheet programs. • Explain what a formula is and how formulas can be used in spreadsheet programs. • List three types of analytical tools commonly found in spreadsheets.
