4. FUNCTION Function is a predefined formula that performs a calculation. Syntax is a set of rules that govern the structure and components for properly entering a function. An Argument is an input, such as cell reference or value, needed to complete a function. A function begins with the equal sign (=) followed by the function name and arguments in parentheses Example: =SUM(A1:A3)

5. INSERTING A FUNCTION When a function is typed, Formula AutoComplete displays a list of functions matching the partial entry Use the Insert Function dialog box to search for a function or select one from a list.

6. FUNCTION CATEGORIES AND DESCRIPTION CategoryDescription CompatibilityContains functions compatible with Excel 2007 and earlier. CubeReturns values based on data in a cube. DatabaseAnalyses records stored in a database format in Excel. Date & TimeProvides methods for manipulating date and time values. EngineeringCalculates values commonly used by engineers. FinancialPerforms financial calculations. InformationProvides information about the contents of a cell. LogicalPerforms logical tests and returns the value of tests. Lookup & Reference Looks up values, creates links to cells, provides references to cells. Math & TrigPerforms standard math and trigonometry functions. StatisticalPerforms common statistical calculations. TextManipulates text strings.

7. SUM SUM is the most commonly used function –represented by a sigma (  ) –Adds values within a specified range Syntax refers to the grammatical structure of a formula –Must adhere to stated structure of formula Arguments are values ─ used as input and returned as output Example: = Sum (B1:B10) Function Name Arguments

8. AUTOSUM Automates the SUM function Click the cell where you want the result Click AutoSum button Select the range of cells you want to sum Press Enter to complete

9. BASIC STATISTICAL FUNCTIONS Perform a variety of calculations to aid in decision making process –AVERAGE calculates the average of a range of numbers –MEDIAN finds the midpoint value in a range –MIN calculates the minimum value in a range –MAX calculates the maximum value in a range –COUNT counts the number of values within a range

10. COUNT Statistical Functions – COUNT, COUNTA COUNT function counts the number of cells in a range that contain numerical data. COUNTA function counts the number of cells in a range that are not blank. COUNTBLANK counts the number of blanks in the given range. Ex: COUNT(C6:C24) COUNTA(E2:E10) COUNTBLANK(J9:J16)

11. MORE MATH AND STATISTICAL FUNCTIONS Function SyntaxDescription =ABS(number)Displays the absolute value of a number =FREQUENCY(data_array,bins_arr ay) Counts how often values appear in given range =INT(number)Rounds a value number down to nearest whole number =MODE.SNGL(number1,[number2],…) Displays the most frequently occuring value in list =PI()Returns the value of pi accurate upto 15 digits =PRODUCT(number1,[number2],… ) Multiplies all values within argument list. =RANDBETWEEN(bottom, top)Generates random numbers between two numbers =ROUND(number, num_digits)Rounds value to specific number of digits =RANK.AVG(number, ref,[order])Returns an average rank for identical values

12. DATE/TIME FUNCTIONS Function SyntaxDescription =TODAY()Displays today’s date: month, day, year =NOW()Displays today’s date and current military time =DATE(year,month,day)Returns serial number for a date =EDATE(start_date,months)Displays serial number of a date a specified number of months in future or past =DAY(serial_number)Displays the day within a month for a serial number =MONTH(serial_number)Returns the month for a serial number =YEAR(serial_number)Identifies the year for a serial number

14. LOGICAL FUNCTIONS IF function Logical Operators OperatorDescription =Equal to <>Not equal to <Less than >Greater than <=Less than or equal to >=Greater than or equal to

15. IF FUNCTION Used to determine whether a given condition has been satisfied or not When the condition is met, the formula performs one task; when it is not met, the formula performs another task Has three arguments: –a condition tested to determine if it is true or false –the resulting value if the condition is true –the resulting value if the condition is false

16. IF CONT.. Flowcharts for the functioning of the If function.

17. IF (CONTD.) Syntax: IF(condition, value_if_true, value_if_false) Value when condition is false Value when condition is true Condition is true or false IF(H4=100, “Good”, “Bad”)

18. NESTED IF The IF function can be nested when you have the multiple conditions to meet. The false value is being replaced by another if function to make the further test. Usually used for having the multiple logical test on the single cell.

19. CONDITIONAL FORMATTING Conditional Formatting highlights or emphasizes cells that meet certain conditions Highlight cells rules Top/Bottom rules Data bars Color scales Icon sets Can create new rules based on your own conditions or using formulas

20. EXAMPLE A conditional formatting rule might be: “If the value is less than $2000, color the cell red.”

21. CREATE THE RULE In our example,we'll create a conditional formatting rule for any cells containing a value higher than 4000. Select the desired cells for the formatting

22. From the Home tab, click the Conditional Formatting comman d. A drop-down menu will appear. Hover the mouse over the desired conditional formatting type, then select the desired rule from the menu that appears. In our example, we want to highlight cells that are greater than $4000

23. A dialog box will appear. Enter the desired value(s) into the blank field. In our example, we'll enter 4000 as our value. Select a formatting style from the drop- down menu. In our example, we'll choose Green Fill with Dark Green Text, then click OK. The conditional formatting will be applied to the selected cells.

24. REMOVE CONDITIONAL FORMATTING Click the Conditional Formatting command. A drop-down menu will appear. Hover the mouse over Clear Rules, and choose which rules you wish to clear. In our example, we'll select Clear Rules from Entire Sheet to remove all conditional formatting from the worksheet.
