4. BASIC FUNCTIONS SUM AVERAGE MAX MIN MEDIAN COUNT RANK 4

5. DATES AND TIME TODAY() NOW() 5

6. CONDITIONAL IF(condition, then, else) –Equal = –Not Equal <> –Less Than <, LT or Equal <= –Greater Than >, GT or Equal >= Example: You want to add bonus points if there is a yes in the bonus column –IF(C2=“YES”,B2+$E$2,B2) 6

9. LOOKUP FUNCTIONS VLOOKUP(value, lookup table, column) –value is the item to look up –the table should use absolute references ($A$1:$B$6) –column is the column in the lookup table to get the return value HLOOKUP(value, lookup table, row) –same as VLOOKUP, but for horizontal lookup tables 9

10. RANGE NAMES Range names make it easier to specify ranges in formulas and find ranges within large spreadsheets –Must begin with a letter or underscore –Only letters, numbers, underscores, and periods You can reference the range in formulas with the name instead of using absolute references 10

11. MANAGING RANGE NAMES Name Box Name Manager Tool –Formulas->Name Manager –Can add, edit, or delete ranges names Use in Formula –Paste Names as documentation –Find name for formula Autocomplete will show range names, double click the name to fill it in 11

12. TEXT MANIPULATION Convert Text to Columns –Data->Text to Columns –Just like importing text files CONCATENATE() –Combines text 12

13. CHANGING CASE PROPER() –Also known as title case –First letter of each word capitalized UPPER() LOWER() 13

14. SUBSTITUTE SUBSTITUTE(text, old text, new text, n) –text: the text you want to make the substitution to –old text: the text you want to remove –new text: the text you want to replace old text with –n: which occurrence to change If n is not specified, all text matching old text will be replaced with new text 14

15. OTHER TEXT FUNCTIONS TRIM() –Removes leading and trailing spaces LEFT(text, n) –Returns the leftmost n characters of text RIGHT(text, n) –Returns the rightmost n characters of text MID(text, start, n) –Returns n characters of text, starting with the character in the position specified by start 15

16. XML eXtensible Markup Language Why use XML?Why use XML Each piece of data has a tag that specifies what it represents A tag is like a label HTML is a specific form of XML with limited tags ( header, bold, etc.) XML can have any tag 16

18. XML SYNTAX Element –Start tag, end tag, and data Tags –Tags use angled brackets <> –End tags must have the same name as the start tag, but are prefixed with a / – data –Tags are case sensitive so you can’t end an with Comments 18

19. XML IMPORT Data Ribbon->From Other Sources->From XML Data Import 19

20. CUSTOM XML IMPORTS File->Open->Select XML File Choose “Use the XML Source task pane” Drag elements to the desired cells Right click on the XML area, XML->Import and select the XML file again Excel will import the data in the format you laid out 20

21. CHARTS Charts are visual representations of data. Important Chart Terms –Chart Area: entire chart –Plot Area: area where data is displayed –Title: brief description of chart –X-axis: labels and scale or category –Y-axis: labels and scale or category –Legend: labels for colors used 21

22. TYPES OF CHARTS Column/Bar Charts –Clustered –Stacked –100% Stacked Line Charts –Simple –Stacked –100% Stacked Pie Charts –Simple –Exploded Pie –Pie of Pie –Bar of Pie Area Charts –Like line charts, but area below line is filled Scatter Plot 22

23. MORE CHART TYPES Stock Charts –High-Low-Close –Open-High-Low-Close (candlestick) –With or without volume (how many shares were traded) data Surface Chart –3D plot of two variables per category Doughnut Chart –Like pie chart, but can show multiple data series Bubble Chart –Like scatter chart, but shows three variables. –The 3 rd variable controls the size of the bubble Radar Chart 23
