### Lesson 2 working with worksheet data

1. 1. WORKING WITH WORKSHEET DATA<br />10/12/2011<br />1<br />Rommel A. Tio<br />
2. 2. There are three types of cell entries in Excel:<br />Labels<br />Values<br />Formula<br />Excel uses the values and formula to perform its calculations.<br />Labels are used to “label” or identify the data on the worksheet so readers can interpret and understand these data.<br />10/12/2011<br />2<br />Rommel A. Tio<br />
3. 3. Data is considered a constant value when you type it directly into a cell. <br />A constant value does not change unless you select the cell and edit the value yourself.<br />Labels and values are constant values.<br />10/12/2011<br />Rommel A. Tio<br />3<br />
4. 4. VALUES<br />A value is the number, including date and time , that you enter in a cell that can be used in calculations or computations.<br />Examples:<br />2000 0.5 20 – Apr – 05 <br />\$ 2000 ½ 9:30 A<br />31. 68 4/20/05 7:20 P<br />50 % <br />10/12/2011<br />Rommel A. Tio<br />4<br />
5. 5. LABELS<br />A label is the text or textual string used in titles and column or row headings, and is not included in calculations.<br />They turn the worksheet full of numbers into a meaningful report by identifying the different types of data it contains.<br />Examples:<br />EMPLOYEE NAME Jane Torres<br />681-0426 1st Quarter<br />10/12/2011<br />Rommel A. Tio<br />5<br />
6. 6. FORMULA<br />A formula is a mathematical expression which consists of a series of values references, and mathematical operators that results in a calculation.<br />The result of a formula appears in the worksheet cell where you entered the formula.<br />10/12/2011<br />Rommel A. Tio<br />6<br />
7. 7. Formula make the spreadsheet program very powerful by linking data in different cells together.<br />Through formula, you can gain power to perform “what if …” calculations simply by changing selected values and having the program recalculate the results.<br />10/12/2011<br />Rommel A. Tio<br />7<br />
8. 8. A worksheet uses symbols called arithmetic operators to tell the computer to perform a mathematical operation.<br />The mathematical operation are:<br />+ addition<br />- subtraction <br />* multiplication<br />/ division<br />^ exponent<br />% percentage<br />10/12/2011<br />Rommel A. Tio<br />8<br />
9. 9. In calculating the mathematical operation, Microsoft Excel follows the PEMDAS rule:<br />() parenthesis and ^ exponent<br />* multiplication and / division<br />+ addition and – subtraction<br />Example<br />result = (2+2)/2*2-2+2^2<br />result = 6<br />When entering a formula precede it with an equal sign =.<br />10/12/2011<br />Rommel A. Tio<br />9<br />
10. 10. FUNCTIONS<br />Functions are built-in formula in Excel that you can use as a quick way of performing a task that would usually take more time if a formula were used.<br />10/12/2011<br />Rommel A. Tio<br />10<br />
11. 11. Functions are always preceded by an equal sign (=) when used at the start of formula.<br />Here are some example of functions:<br />= SUM (A1:D1)<br />= 25 – SUM(A5:A12)<br />10/12/2011<br />Rommel A. Tio<br />11<br />
12. 12. ENTERING LABELS<br />In creating your worksheet, start with making your label entries: the main and subheading, the column headings, and the row headings. <br />You need not worry if you miss or need to delete some labels. You can always insert, or delete rows and columns through the Insert menu -> rows and columnscommands.<br />10/12/2011<br />Rommel A. Tio<br />12<br />
13. 13. Labels, like the text in word processing, can be formatted. A number can be entered as a label so that Excel does not include it in its calculations. <br />Examples of number that you might use as labels include a year (e.g., 2005), an area or ZIP code (e.g. 1900) and a tax declaration number or TIN (e.g. 421-952-888)<br />10/12/2011<br />Rommel A. Tio<br />13<br />
14. 14. TO ENTER A TEXT LABEL<br />Click on the cell where you want to enter a label<br />Type a label. A label can include uppercase or lowercase letters, spaces, punctuation marks and numbers. The entire entry appears simultaneously on the formula bar and in the cell as you type. You can enter up to 255 characters into a cell. Labels are entered, by default, as left justified. To cancel a cell entry while typing, click on the Cancel formula box X, or simply press Esc.<br />10/12/2011<br />Rommel A. Tio<br />14<br />
15. 15. Command Excel to “accept” your data entry by doing any one of the following:<br />Click on the Enter formula box √ on the formula bar to leave the insertion point in the active cell.<br />Click on the another cell.<br />Press the enter key to move the insertion point down one cell.<br />Press an arrow key or the Tab Key.<br />Note: To erase any existing cell entry, select the cell gain press Del.<br />10/12/2011<br />Rommel A. Tio<br />15<br />
16. 16. TO ENTER A NUMBER AS A LABEL<br />Click on the desired cell.<br />Type an apostrophe (‘). The apostrophe, when used as a label prefix, does not appear on the worksheet. It instructs Excel to treat the data entry as text not as a value.<br />Type a number. To complete the data entry, press Enter or Tabor an arrow key, or click on the Enter formula box on the Formula bar or click on another cell.<br />10/12/2011<br />Rommel A. Tio<br />16<br />
17. 17. DEALING WITH SPILL OVERS<br />Occasionally, you may enter a label that is wider that the cell it occupies. When that happens, Excel allows your text to spill into the next cell(s) to the right of the active cell so long as those cells are empty.<br />This feature is useful especially for entering a main heading label.<br />10/12/2011<br />Rommel A.
