Transcription

1 OBJECTIVE We will practice using formulas and functions in. ESSENTIAL SKILLS Enter formulas by typing Enter formulas by Point mode Apply the AVERAGE, MAX, and MIN functions Verify a formula using Range Finder Review from Chapter 1 Entering Titles and Numbers into the Worksheet (EX 71 72) To Change Document Properties (EX 73) To Change the Sheet Name (EX 74) Entering Formulas (EX 74) Excel will the result if you enter a formula into a cell. Excel recalculates the product whenever new values are entered into the cell references used in the formula. TO ENTER A FORMULA USING THE KEYBOARD (EX 75) The (=) alerts Excel that you are entering a formula or function and not text. Excel colors the borders of the cells referenced in the formula to help with the reviewing process. Arithmetic Operations (EX 76) Complete the table below using information from Table 2-2 in the text: OPERATOR MEANING EXAMPLE OF USAGE MEANING - Negative Negative 78 % =23% Multiplies 23 by 0.01 Exponent =3^4 Raises 3 to the fourth power Multiply =61.5*C5 Multiplies the contents of cell C5 by 61.5 / =H3/H11 Divides the contents of H3 by the contents of H11 + Adds 11 and 9 - Subtract =22-F15 Subtracts the contents of cell F15 from 22 Order of Operations (EX 77) When more than one arithmetic operator is involved in a formula, Excel follows the same basic order of operations that you would use in algebra. Moving from left to right in a formula, the order of operations is as follows: 1) 2) 3) 4) 5) 1 P a g e

2 Just like in algebra, you can use to override the order of operations. For example, calculate the following using the order of operations: = 8 * = compared with = 8 * (3 + 2) = To Enter Formulas Using Point Mode (EX 77) An alternative to entering formulas in cells using the keyboard is to use the mouse and Point mode. Point mode allows you to cells for use by clicking with the mouse. Option Buttons (EX 82) Excel displays Option Buttons in a workbook while you are working to indicate that you can complete an operation using automatic features. Complete the table below. BUTTON NAME FUNCTION Auto Fill Options Gives options for how to fill cells, such as dragging the fill handle Undoes an automatic correction, stops future automatic corrections, or causes Excel to display the AutoCorrect Options dialog box Lists formatting options when you insert cells, rows, or columns Specifies how moved or pasted items should appear Lists error-checking options if an invalid formula is entered To Determine Totals Using the Sum Button (EX 82) Select the cell to contain the sum. Click the Sum button on the tab in the group. Using the AVERAGE, MAX, and MIN Functions (EX 84) With Excel, you can enter functions using one of five methods: 1) 4) 2) 5) 3) 2 P a g e

3 The method you choose will depend on your typing skills and whether you can recall the function name and required arguments. To Determine the Average of a Range of Numbers (EX 84) The AVERAGE function the numbers in the specified range and then the sum by the number of cells with numeric values in the range. For example, calculate the average of the following equation: = ( ) / 5 = To Determine the Highest Number in a Range of Numbers (EX 86) Excel also includes the MAX function, which displays the value. To Determine the Lowest Number in a Range of Numbers (EX 87) The MIN function determines the (minimum) number in a range. Verifying Formulas Using Range Finder (EX 91) Using an incorrect in a formula is one of the most common mistakes made with Excel. An easy way to verify that a formula is referencing the cell you want it to reference is by using the Excel Range Finder. Range Finder checks which cells are referenced in the formula that is in the active cell. To use Range Finder, -click on the cell with the formula you want to check. Excel will highlight the cells that are referenced in the formula. Formatting the Worksheet (EX 92 99) TO CHANGE THE WORKBOOK THEME Go to the tab. Click the button. TO FORMAT THE WORKSHEET TITLES Go to the tab. Select the title range, then click the button to merge and center the text. Select the title range, then click the button to display the cell styles gallery. Click the Title cell style. 3 P a g e

4 TO CHANGE THE BACKGROUND COLOR AND APPLY A BOX BORDER Select the range, then click the button arrow on the Home tab in the Font group to display the gallery. Choose the Fill Color to change the background. Click the button on the Home tab in the Font group to display the Borders list. Click the Thick Box Border to display a thick box border around the selected range. TO FORMAT DATES IN CELLS Select the range to contain the new date format. Click the Format Cells: Number Dialog Box Launcher on the Home tab in the Number group. Formatting Numbers Using the Ribbon (EX 100) The Number format is applied to currency amounts. The style is applied to the remaining range of numbers. The Accounting Number Format and Comma Style buttons are located on the tab in the group. TO APPLY A CURRENCY STYLE FORMAT (EX 102) Select the range to be formatted. Click the Format Cells: Number Dialog Box Launcher button. Select the Number tab. Click Currency in the category list to view the style options available. Conditional Formatting (EX 104) Excel lets you apply formatting that appears only when the value in a cell meets conditions that you specify. This type of formatting is called conditional formatting. A is made up of two values and a relational operator. It is a true or false statement that applies to the cells in the range. If it is true, Excel applies the formatting. If it is false, Excel suppresses the formatting options. TO APPLY CONDITIONAL FORMATTING Select the range. Click the Conditional Formatting button on the tab in the group. Click in the list to display the New Formatting Rule dialog box. 4 P a g e

5 Click Format only cells that contain in the Select a Rule Type area. Select the desired relational operator, then enter the desired value to complete the new rule for conditional formatting. Click the button. Choose a Fill Color. Click OK to close the formatting box. Click OK to assign the conditional format. Conditional Formatting Operators (EX 107) Relational operators include the following (use Table 2-5): Changing the Widths of Columns and Heights of Rows (EX 107) When Excel starts and displays a blank worksheet on the screen, all of the columns have a default width of characters, or pixels. These values may change depending on the theme applied to the workbook. Pixel is short for picture element. A pixel is a on the screen that contains a. The size of the dot is based on your screen s resolution. The default row height in a blank worksheet is points, or pixels. Fifteen points is equal to about 1/5 of an inch. TO CHANGE THE WIDTHS OF COLUMNS You can set the width of columns manually or use best fit, which means that the width of the column will be increased or decreased to allow the widest entry to fit. Checking Spelling (EX 112) Excel includes a spell checker to help you check a worksheet for spelling errors. TO CHECK SPELLING ON THE WORKSHEET Select cell so that the spell checker starts at the beginning of the worksheet. Go to the tab on the Ribbon. Click the Spelling button. 5 P a g e

6 Preparing to Print the Worksheet (EX 114) Page Layout view allows you to create or modify a worksheet while viewing how it will look in printed format. The default view you typically work in is called view. TO CHANGE THE WORKSHEET S MARGINS Margins are those portions of a printed page outside the main body of the printed document and are always blank when printed (the white border around the page). Click the button on the status bar to view the worksheet in Page Layout view. Go to the tab in the Ribbon. Click the Margins button to display the gallery, and select the appropriate margin size (normal, wide, narrow, custom). TO CHANGE THE WORKSHEET S HEADER (EX 115) Click above the worksheet title in the center area of the Header. Type text for the header. Click anywhere inside the worksheet to deselect the header. TO CHANGE THE WORKSHEET S ORIENTATION (EX 116) On the Page Layout tab, click the button. Choose Landscape or Portrait. Displaying and Printing the Formulas Version of the Worksheet (EX 119) You have been working with the values version of the worksheet, which shows the results of the formulas you have entered as Excel calculates for you. Excel can also display and print in the formulas version, which shows the actual formulas entered into each cell instead of the resulting values. The formulas version is useful for a worksheet, which is the process of finding and correcting errors in the worksheet.
