1. Lesson: 4 Spreadsheets After completing this lesson, you will be able to: Identify the components of a spreadsheet. Enter data into a spreadsheet. Perform basic mathematical tasks in a spreadsheet. Insert charts in a spreadsheet. Explain the purpose of various options available for printing a spreadsheet.

2. Entering Text Text: data that has no numeric value associated with it. Number: constant numeric value, such as the test scores attained by a student. Formulas and functions: mathematical equations. The numeric value of formulas and functions automatically changes when the numeric value of variables associated with them changes

3. To Enter Data: Open Excel To enter data, click cell C1. Edit data Copy & paste contents of a cell Move the contents of a cell – Cut & paste To select a range of cells in a column To select a range of cells in a row

4. To Enter Data, cont’d. Insert a new row Insert a new column Column Width Row Height Delete a column/row Sort data Rename worksheet Save workbook

5. Performing Mathematical Tasks Function - an operation that is performed on the data in the cells by using calculation tools available in the program AVERAGE SUM MIN MAX

6. Performing Mathematical Tasks Formula (in B7) =B1+B2+B3+B4+B5+B6 Function (in B7) =SUM(B1:B6) All functions/formulas begin with = Formulas and functions refer to the cell address, not the data in the cells. When you change the data in a cell; the result of the formula is updated automatically. Function Wizard - automatically prompts you for the information necessary for the function to be completed.

7. Performing Mathematical Tasks (cont’d.) Add values Edit formula in the formula bar Copy/Paste or Cut/Paste a formula Delete a formula Insert function

8. Inserting Charts Represent numeric data in the form of charts – Pie – Line – Bar

9. Pie Chart - indicates the percentage spent on items such as groceries

10. Line Graph – Compares variables or shows the relationship between them X-axis - horizontal line Y-axis - vertical line

11. Bar Chart

12. Inserting Charts Select data to be included Insert chart Select chart type Enter title

13. Printing Data Print Preview Page Setup Orientation – Landscape – Portrait Grid lines Column and Row Headings Print a chart

14. True or False Spreadsheet - Quiz 1. You CANNOT store text, numbers, or formulas in a cell. 2. You CAN store text, numbers, or formulas in a cell. 3. A column in a worksheet is identified by a LETTER. 4. A column in a worksheet is identified by a NUMBER. 5. A cell range CANNOT extend across multiple rows. 6. A cell range CAN extend across multiple rows. 7. A cell VALUE indicates an active cell. 8. A cell POINTER indicates an active cell.

15. 9. A workbook CAN contain more than one worksheet 10. A workbook CANNOT contain more than one worksheet. 11. A WORKBOOK is a file created in Excel. 12. A WORKSHEET is a file created in Excel. 13. ONLY ONE cell can be active at a time. 14. MORE THAN ONE cell can be active at a time. 15. A cell address indicates the exact location of a ROW. 16. A cell address indicates the exact location of a CELL. 17. A label HAS a numeric value attached to it. 18. A label DOES NOT HAVE a numeric value attached to it.
