Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 2 Objectives Identify the parts of a function formula. Use function formulas to solve mathematical problems. Use function formulas to solve statistical problems. Use function formulas to solve financial problems. Use function formulas to insert times and dates in a worksheet. Use logical function formulas to make decisions with worksheet data.

Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 4 Identify the Parts of a Function Formula A function formula has three components: – the equal sign – a function name – an argument The argument is a value, cell reference, range, or text that acts as an operand in a function formula. Example: =SUM (E4:E22)

Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 5 Solving Mathematical Problems Mathematical and trigonometric functions are particularly useful for determining values such as: – Logarithms – Factorials – Sines – Cosines – Tangents – Absolute values See Table 5-1 in student book, Mathematical and trigonometric functions

6
Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 6 Solving Statistical Problems Statistical functions can also be used to determine: – Average – Standard deviation – Variance – Maximums – Minimums – Counts See Table 5-1 in student book, Statistical functions

7
Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 7 Solving Financial Problems Financial functions are used to analyze loans and investments: – Value of a series of equal payments – Present value of an investment – Payments required to repay a loan See Table 5-3 in student book, Financial functions

8
Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 8 Inserting Times and Dates Date and time functions may be used to – Convert serial numbers to a month, a day, or a year – Insert the current date or current time. See Table 6-4 in student book, Time, date, and text functions

9
Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 9 Using Logical Function Formulas Logical functions, such as the IF function, may be used to display text or values if certain conditions exist. For example the IF function will determine whether a student has passed or failed a course. The function formula IF(C4>60,“PASS”,“FAIL”) will display “PASS” if the value in C4 is greater than 60 and “FAIL” if the value in C4 is not greater than 60.

10
Excel – Lesson 5 Microsoft Office XP: Introductory Course Pasewark & Pasewark 10 Summary Function formulas are special formulas that do not require operators. Excel has more than 300 function formulas. Function formulas may be used to perform mathematical, statistical, financial, and logical operations. Function formulas may also be used to format text and insert dates and times.
