3 Excel Functions- Test 2 Logical Functions AND OR NOT IF Mathematical Functions ROUND Statistical Functions LARGE SMALL Text Manipulation Concatenate

4 Microsoft  Excel  Logical Functions AND =AND(logical1, [logical2],...) OR =OR(logical1, [logical2],...) NOT =NOT(logical) IF =IF(logical_test, [value_if_true], [value_if_false])

5 Microsoft ® Excel ® Logical Functions Syntax: =AND(logical1, [logical2],...) Arguments: logical1 Required  The first condition that you want to test that can evaluate to either TRUE or FALSE. logical2,... Optional  Additional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.

6 Microsoft ® Excel ® Logical Functions Description: Returns FALSE if one or more arguments is FALSE Otherwise, all arguments must evaluate TRUE Remarks: Arguments must evaluate to logical values Arguments must be arrays or references that contain logical values Text and empty cells are ignored in arrays or references Errors: #VALUE – If no logical values exist in a specified range

9 Microsoft ® Excel ® Logical Functions Syntax: =OR(logical1, [logical2],...) Arguments: logical1 Required  The first condition that you want to test that can evaluate to either TRUE or FALSE. logical2,... Optional  Additional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.

10 Microsoft ® Excel ® Logical Functions Description: Returns TRUE if one or more arguments is TRUE Otherwise, all arguments must evaluate FALSE Remarks: Arguments must evaluate to logical values Arguments must be arrays or references that contain logical values Text and empty cells are ignored in arrays or references Errors: #VALUE – If no logical values exist in a specified range

11 Microsoft ® Excel ® Logical Functions  

12 Microsoft ® Excel ® Logical Functions Syntax: =NOT(logical) Arguments: logical Required  A value or expression that can be evaluated to TRUE or FALSE.

13 Microsoft ® Excel ® Logical Functions Description: Reverses the value of its argument. Remarks: If logical is FALSE, NOT returns TRUE if logical is TRUE, NOT returns FALSE Errors: None

14 Microsoft ® Excel ® Logical Functions

15 Syntax: =IF(logical_test, [value_if_true], [value_if_false]) Arguments: logical_test Required  Any value or expression that can be evaluated to TRUE or FALSE. value_if_true Optional The value that you want to be returned if the logical_test argument evaluates to TRUE. If logical_test evaluates to TRUE and the value_if_true argument is omitted (that is, there is only a comma following the logical_test argument), the IF function returns 0 (zero). To display the word TRUE, use the logical value TRUE for the value_if_true argument.

16 Microsoft ® Excel ® Logical Functions Syntax: =IF(logical_test, [value_if_true], [value_if_false]) Arguments: value_if_false Optional  The value that you want to be returned if the logical_test argument evaluates to FALSE.  If logical_test evaluates to FALSE and the value_if_false argument is omitted, (that is, there is no comma following the value_if_true argument), the IF function returns the logical value FALSE.  If logical_test evaluates to FALSE and the value of the value_if_false argument is omitted (that is, in the IF function, there is a comma following the value_if_true argument), the IF function returns the value 0 (zero).

17 Microsoft ® Excel ® Logical Functions Description: The IF function returns one value if a condition you specify evaluates to TRUE, and another value if that condition evaluates to FALSE. Remarks: Up to 7 IF functions can be nested as value_if_true and value_if_false arguments to construct more elaborate tests. (2003) Up to 64 IF functions can be nested as value_if_true and value_if_false arguments to construct more elaborate tests. (2007) If any of the arguments to IF are arrays, every element of the array is evaluated when the IF statement is carried out. Errors: None

18 Microsoft ® Excel ® Logical Functions value_if_true  [value_if_false]

19 Nested If in Excel A nested IF statement says something like... "If the answer is yes, do this. If the answer is no do this or this (depending on...“ Syntax: IF( condition1, value_if_true, IF( condition2, value_if_true, value_if_false )) Microsoft ® Excel ® Date Functions

20 Nested IF Contd. What was the percentage grade you got on your last test?75% You got a C =IF(F42<60%,"Sorry, you failed",IF(F42<70%,"You got a D",IF(F42<80%,"You got a C",IF(F42<90%, "You got a B", "WOW you got an A!!!")))) Cell Address is F42

21 Example- Nested IF Excel) A customer applies for a 30-year mortgage at their employer-sponsored credit union, which offers borrowing terms based on the customer's "FICO" (which has been set-up as a defined name in a worksheet) credit score. Write a formula to determine the rate. –Mortgage application denied if score is less than 600 –Interest rate of 6% if score is –Interest rate of 5% if score is –Interest rate of 4% if score is over 800 =IF (FICO<600,"Denied",IF(FICO<700,6%, IF(FICO<800,5%,4%)))

24 Microsoft ® Excel ® Mathematical Functions Description: Rounds a number to a specified number of digits. Remarks: If num_digits is greater than 0 (zero), then number is rounded to the specified number of decimal places. If num_digits is 0, the number is rounded to the nearest integer. If num_digits is less than 0, the number is rounded to the left of the decimal point. Errors: None

25 Microsoft ® Excel ® Mathematical Functions =ROUND(-1.475,2) Rounds to two decimal places

65 MIS PRACTICE Question (MIS, Ch 4) Hardware, in computer terms, refers to the physical components of the computer. Answer True False

66 MIS PRACTICE Question (MIS, Ch 4) Businesses that handle large volumes of retail transactions often store this data in a corporate data center on mainframe computers, which many I.T. professionals fondly refer to as “big iron” in their lingo. Answer True False

67 MIS PRACTICE Question (MIS, Ch 4) Because _____ reduces the amount of paper in organizations, some of its most enthusiastic adopters are companies in paper-intensive fields such as law, retail, insurance, and banking. Answer processing OMR imaging printing

68 MIS PRACTICE Question (MIS, Ch 5) To accelerate their work, application developers can use one of several _____ programming languages, such as Microsoft Visual Basic, Borland Delphi, Micro Focus COBOL, ASNA Visual RPG, and Visual C++. Answer visual

69 MIS PRACTICE Question (MIS, Ch 4) What factors make one computer more powerful than another? Answer The two major factors to consider are processing speed and memory capacity. A computer’s speed is determined, among other factors, by the CPU clock rate (measured in MHz or GHz), and the amount of information the CPU can process per cycle (determined by the size of the data word and the capacity of internal data communication, which is often referred to as bus width). However, the architecture of the various computer components also plays a significant role in determining processing speed. To mention one, consider the discussion of multi-core CPUs. When two computers are built with the same components except the number of cores, the computer with the greater number of cores is faster.

70 MIS PRACTICE Question (MIS, Ch 5) Which of the following refers to sophisticated and interactive multimedia applications that run on more powerful personal computers? Answer polymedia hypermedia virtual reality temporal reality

71 MIS PRACTICE Question (MIS, Ch 5) The most sophisticated virtual reality (VR) devices provide which of the following elements? (select one or more answers) Answer immersion interaction intersection immobility

72 Sample Questions Question (MIS, Ch 4) The data access mode for tape storage devices is: (A)direct (B) random (C) sequential (D) none of the above

73 Sample Questions Question (MIS, Ch 5) Which of the following is considered to be a type of systems software? (A) compilers (B) communications (C) interpreters (D) utilities (E) all of the above

74 Sample Questions Assume that cell A1 shows the total quantity (in gallons) of fuel purchased and cell B1 is the price per gallon. Provide a formula that will correctly calculate the total amount that a person should pay,after the discount (if any) has been applied. =IF(A1<50, A1*B1, A1*B1*95%) and then apply some algebra to get: =A1*B1*IF(A1<50, 1,.95) note the different format (no percent)

75 Sample Questions Question (MIS, Ch 5) Since Microsoft does not make the source code for Internet Explorer available for end users to review and update, the product is considered proprietary. True False
