1. Excel Review By Mr. Griffin Elmira Business Institute

2. Identify Excel components

3. Descriptions of Excel components

4. Excel’s arithmetic operators Arithmetic operations, symbols and description of their use.

5. Know the order of precedence The order of precedence rules must be considered when creating expressions. The chart below illustrates Excel’s order of precedence and shows sample expressions and the result of each expression.

6. Key Excel Terminology Spreadsheet Column, Row Formula, Function Format Worksheet, Workbook, File Absolute, Relative Adjacent, Nonadjacent

7. Functions What exactly are functions? Why do we use functions?

8. Sum Function Used to add a group of numbers Format Single Range=sum(a1:a20) Multiple Ranges, Adjacent Columns =sum(a1:b20) Multiple Ranges, Nonadjacent Columns =sum(a1:a20,c1:c20)

9. Average Function Calculates the Average Format Single Range=average(a1:a20) Multiple Ranges, Adjacent Columns =average(a1:b20) Multiple Ranges, Nonadjacent Columns =average(a1:a20,c1:c20)

10. Max and Min Functions Max – finds the largest number in a given range =max(a1:a20) or =max(a1:b20) or =max(a1:a20,c1:c20) Min – Finds the smallest number in a given range =min(a1:a20) or =min(a1:b20) or =min(a1:a20,c1:c20) –Return highest or lowest, values from an argument list Argument list may include cell references, cell ranges, values, functions, or formulas Cells that are empty or contain text are not included

11. Other functions *** These functions are written the same way as the Sum function – they follow the same exact rules. =median(range)Example =median(a1:a20) Returns median of the range =stdev(range)Example =stdev(a1:a20) Returns the Standard Deviation of the Range =mode(range)Example =mode(a1:a20) Returns the Mode of range These functions follow the same rules as the Sum function – adjacent/nonadjacent, multiple ranges, etc.. *** not on the Excel Exam

12. Counting Functions Count Counta Countif Countblank

13. COUNT FUNCTION Count – counts numeric entries

14. COUNTA FUNCTION Counta- counts all entries in a given range – numeric entries and text entries

15. Countif Function Countif- counts entries in a specific range that meet criteria

16. Countblank Function Countblank – counts blank entries in a given range

17. Sumif Function Sumif- adds entries that meet specific criteria

18. PMT Function Calculates Payment

19. Vlookup Vlookup- vertical lookup function Allows Excel to look up a value in a table and return a related value Requires three arguments: –the numeric value (or cell) to look up –the range of the table –the column number containing the value you want to return Cousin of the Hlookup

20. Today function Places current date on the spreadsheet Can be used in time/date calculations

21. Rank Function Ranks cells in a spreadsheet. Orders cells in 1-2-3 order

22. If Fuction Enables decision making in a worksheet Requires three arguments: –A condition –A value if the condition is true –A value if the condition is false Condition must be able to be evaluated as true or false –Uses relational operators (=, <, etc.)

23. Formatting your Spreadsheet

24. Graphing

25. Common Error Messages #value – Excel expected to find a number, but found text – check your formula #ref – the cell referenced in the formula is not found – often from typing errors- named cells or cells located on other sheets – check your formula ##### - generally not an error at all. You need to resize your column width.

26. Calculating Percentages

27. Page Setup Page tab controls print orientation and scaling Margins tab is used to set top, bottom, left and right margins

28. Page Setup (continued) Header/Footer tab allows user to create headers and footers for each printed sheet Sheet tab is used to control repeating rows or columns or print gridlines

29. Display the Cell Formulas CTRL + ~
