CONCATENATE The Concatenate function joins text together from different cells. In this example, it joins several text strings to form the account number 100-04-1000-730.00-1081-07.

2 IF The IF function will do a comparison and give you a result. In this example, the IF function looks at cell H5 to determine if it is less than 150,000. It will write the word Less if H5 is indeed less than 150,000 (True). It will write the word More is H5 is more than 150,000 (False). Here it says Less. CONCATENATE The Concatenate function joins text together from different cells. In this example, it joins several text strings to form the account number RIGHT The Right function will look at the rightmost character or characters in a text string and extract those. In this example, the text string is always cell B4. The number of characters to extract from the school year is the last 2 characters. The result is

COUNTA - The COUNTA function will examine a set of cells and tell you how many cells are not

COUNTBLANK - The COUNTBLANK function will examine a set of cells and tell you how many cells

COUNTIF - The COUNTIF function will examine a set of cells and tell you how many cells fit

3 COUNTA - The COUNTA function will examine a set of cells and tell you how many cells are not empty. In this example, Excel analyzed 19 cells and found that only 18 were not empty. COUNTBLANK - The COUNTBLANK function will examine a set of cells and tell you how many cells are empty. In this example, Excel analyzed 19 cells and found that 2 were empty. COUNTIF - The COUNTIF function will examine a set of cells and tell you how many cells fit the criteria you specify. In this example, Excel analyzed 19 cells looking for the entry of C and found it 10 times. 31

Out of all these cells, it has found that 5,000 is the smallest value.

4 MIN - The MIN function looks at sets of values and finds the smallest value. In this example, it examines cells F28 through F35 and cells H28 through H32. Out of all these cells, it has found that 5,000 is the smallest value. TODAY This gives you today s date IF the cell is formatted as a date. COUNT The COUNT function will examine a set of cells and tell you how many cells contain numbers. In this example, Excel analyzed 19 cells and found that only 3 had number values. 30

AVERAGE The AVERAGE function in this example will add together cells F28 through F35 and divide by 8 because there are 8 numbers. Notice that it will show your result is $8,000

5 AVERAGE The AVERAGE function in this example will add together cells F28 through F35 and divide by 8 because there are 8 numbers. Notice that it will show your result is $8, MAX The MAX function looks at sets of values and finds the largest value. In this example, it examines cells F28 through F35 and cells H28 through H32 and cells H20 through H25. Out of all these cells, it has found that $15, is the largest value. 29

6 to the Number 2 field. Click OK when all the cells for the function have been selected. Some commonly used functions shown below are described using their formula palette. Remember that you get the formula palette by clicking on the Function Wizard. SUM - This says to add together cells F28 through F35. Notice that it will show your result is SUMIF - Use the SUMIF when you want to place restrictions on numbers you add in a column or row. In this example, you want to add the numbers from cells H28 through H32 IF they are greater than Notice that it will show your result is

7 Function Wizard All functions built into Excel can be viewed by using the Function Wizard. To use the Function Wizard click on the cell where the function will be placed and click the Function Wizard button on the standard toolbar. From the Paste Function dialog box, browse through the functions by clicking in the Function category menu on the left and select the function from the Function name choices on the right. As each function name is highlighted a description and example of use is provided below the two boxes. Click OK to select a function. The formula palette will sometimes open if cells need to be selected or criteria need to be stipulated. This window allows you to choose the cells that will be included in the function. In the example below, cells B4 and C4 were automatically selected for the sum function by Excel. The cell values {2, 3} are located to the right of the Number 1 field where the cell addresses are listed. If another set of cells, such as B5 and C5, needed to be added to the function, those cells would be added in the format "B5:C5" 27

SUM function and simply type "=SUM(D1:D10)". The colon shows that you have chosen a range of cells from cell D1 to cell D10. Another way to list cells in a formula or function is to use a comma.

8 SUM function and simply type "=SUM(D1:D10)". The colon shows that you have chosen a range of cells from cell D1 to cell D10. Another way to list cells in a formula or function is to use a comma. =SUM(B2:B5,B7, B10:B13) says to add cells B2, B3, B4, B5, B7, B10, B11, B12, and B13. Autosum - Use the Autosum function to add the contents of a cluster of adjacent cells. Select the cell that the sum will appear in that is outside the cluster of cells whose values will be added. Cell C2 was used in this example. Click the Autosum button (Greek letter sigma) on the standard toolbar. Highlight the group of cells that will be summed (cells A2 through B2 in this example). You can hold the CONTROL if the cells you wish to sum are not adjacent to one another. Press the ENTER key on the keyboard or click the green check mark button on the formula bar. Several other functions and examples are given in the table below: Function Example Description SUM =SUM(A1:100) finds the sum of cells A1 through A100 AVERAGE =AVERAGE(B1:B10) finds the average of cells B1 through B10 MAX =MAX(C1:C100) returns the highest number from cells C1 through C100 MIN =MIN(D1:D100) returns the lowest number from cells D1 through D100 SQRT =SQRT(D10) finds the square root of the value in cell D10 TODAY =TODAY() returns the current date (leave the parentheses empty) 26

9 Autofill allows you to drag the fill handle of a cell to copy the formula from that cell to other cells in the same row or column. The fill handle of a cell is the small black square at the bottom right corner of a cell. To fill a row or a column, click on a cell or a block of cells when your pointer looks like a large plus sign. Then move your pointer to the fill handle, click and hold on the mouse, drag to the cells to fill in the formula and formatting. Relative, Absolute, and Mixed Referencing Relative Reference - Calling cells by just their column and row labels (such as "A1") is called relative referencing. When a formula contains relative referencing and it is copied from one cell to another, Excel does not create an exact copy of the formula. It will change cell addresses relative to the row and column they are moved to. For example, if a simple addition formula in cell C1 that says "=(A1+B1)" is copied to cell C2, the formula would change to "=(A2+B2)" to reflect the new row. Absolute Reference If you wish to autofill a formula, but you do not want a cell address to change in the formula, you must modify the formula slightly. To prevent this change, cells must be called by absolute referencing and this is accomplished by placing dollar signs "$" within the cell addresses in the formula. Continuing the previous example, the formula in cell C1 would read "=($A$1+$B$1)" if the value of cell C2 should be the sum of cells A1 and B1. Both the column and row of both cells are absolute and will not change when copied. Mixed referencing can also be used where only the row OR column fixed. For example, in the formula "=(A$1+$B2)", the row of cell A1 is fixed and the column of cell B2 is fixed. Basic Functions Functions can be a more efficient way of performing mathematical operations than formulas. For example, if you wanted to add the values of cells D1 through D10, you would type the formula "=D1+D2+D3+D4+D5+D6+D7+D8+D9+D10". A shorter way would be to use the 25

10 Subtotal in cell C7 in the table is to type =C2+C3+C4+C5 and hit ENTER on the keyboard. The result of the addition formula will show up in the cell and the formula will show the formula. Spaces are not needed in a formula. 24

<= Less than or equal to > Greater than >= Greater than or equal to <> Not equal to Formulas Formulas are entered in the worksheet cell and must begin with an equal sign "=".

11 <= Less than or equal to > Greater than >= Greater than or equal to <> Not equal to Formulas Formulas are entered in the worksheet cell and must begin with an equal sign "=". The formula then includes the addresses of the cells whose values will be manipulated with appropriate operands placed in between. After the formula is typed into the cell, the calculation executes immediately and the formula itself is visible in the formula bar. See the example below to view the formula for calculating the sub total for a number of textbooks. The formula multiplies the quantity and price of each textbook and adds the subtotal for each book. To type a formula, click in the cell where you want the results of the formula. Type = first. You can type the address of a cell, like B5, or you can click in cell B5 and Excel will type the address for you in the formula. Use the operands to create a mathematical formula. Another way to get the 23

Formulas and Functions The distinguishing feature of a spreadsheet program such as Excel is that it allows you to create mathematical formulas and execute functions. Otherwise, it is not much more than a large table for displaying text. These pages will show you how to create these calculations. Order of operations in Excel 2000 There are many formulas that help you calculate or analyze everything from finances to statistical sampling plans. When you combine several mathematical steps in a formula, they are performed in a specific order. Excel 2000 starts calculating from the left to the right according to the following order of operations: Order Symbol Description 1 () Parentheses 2 - Negative number if used with one operand 3 % Percentage 4 ^ Exponentiation 5 * and / Multiplication and division 6 + and - Addition and subtraction 7 & Connects two text values to produce one 8 Continuous text value arison Oper ators = Equal to < Less than 22

33 I. Spreadsheet Basics HIT 201-Excel I Screen Shots Microsoft Excel 2000 Excel allows you to create spreadsheets much like paper ledgers that can perform automatic calculations. Each Excel file is a workbook that can hold many worksheets. The worksheet is a grid of columns (designated by letters) and rows (designated by numbers). The letters and numbers of the columns and rows (called labels) are displayed in gray buttons across the top and left side of the worksheet. The intersection of a column and a row is called a cell. Each cell on the spreadsheet has a cell address that is the column letter and the row number. Cells can contain text, numbers, or mathematical formulas. 1
