1 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall. 1 by Mary Anne Poatsy, Keith Mulbery, Lynn Hogan, Amy Rutledge, Cyndi Krebs, Eric Cameron, Rebecca Lawson Chapter 2 Formulas and Functions

2 Use relative, absolute, and mixed cell references in formulas Correct circular references Insert a function Insert basic math and statistical functions Use date functions 2 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

3 Determine results with the IF function Use lookup functions Calculate payments with the PMT function Create and maintain range names Use range names in formulas 3 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

4 Excel offers three types of cell references for use when a formula is copied – Absolute$A$1 – RelativeA1 – Mixed$A1 or A$1 $ indicates that the row number or column letter will not be modified during a copy 4 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

5 A relative cell reference indicates a cell’s relative location from the cell containing the formula. 5 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

6 An absolute cell reference provides a permanent reference to a specific cell 6 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

7 In mixed reference $B4, the column is fixed, but the row may be altered during a copy In mixed reference B$4, the row is fixed, but the column may be altered during a copy 7 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

8 A circular reference error occurs if a formula refers to itself 8 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

9 An Excel function is a predefined formula that performs a calculation 9 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

10 Syntax is the set of rules that govern correct formation of a function An argument is an input, such as a cell or range A function begins with the equal sign (=) followed by the function name and arguments in parentheses Example: =SUM(A1:A3) 10 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

11 When a function is typed, Formula AutoComplete displays a list of functions matching the partial entry 11 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

12 A function ScreenTip is a small pop-up description that displays the function arguments. 12 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

13 Use the Insert Function dialog box to search for a function or select one from a list 13 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

14 The Function Arguments dialog box offers help on each argument 14 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

15 The SUM function returns the mathematical sum of some number of cells or ranges; for example: =SUM(A1:A3) =SUM(A1,B3,C5) =SUM(A1:B3,C5:E8) 15 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

16 Common statistical functions include: – AVERAGEarithmetic mean – MEDIANmidpoint value – MINminimum value – MAXmaximum value – COUNTnumber of values in range – COUNTBLANKnumber of empty cells – COUNTAnumber of nonempty cells 16 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

19 A nested function occurs when one function is embedded as an argument to another function; for example: =IF(A1

20 Since dates are numeric, calculations can be performed, such as subtraction The TODAY function displays the current date The NOW function displays the current date and time 20 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

21 =IF(logical_test, value_if_true,value_if_false) The IF function has three arguments: – A condition that is tested to determine if it is either true or false – The resulting value if the condition is true – The resulting value if the condition is false 21 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

22 The logical test is built from the logical operators 22 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

23 23 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

24 Lookup functions are used to look up values in a table to perform calculations or display results – For example, a teacher may want to look up an average in order to assign a grade 24 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

25 When searching a range, the breakpoint is the lowest value for a category or series A lookup table typically lists breakpoints in one column and return values in a second column 25 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

26 The VLOOKUP function searches a lookup table for a value and returns the result from the related column VLOOKUP has three required arguments: – Lookup value – Table array (range of lookup table) – Column index of return value 26 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

27 27 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

28 The HLOOKUP function is used when the breakpoints and return data are placed in rows The third argument now lists the row index 28 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

29 The PMT financial function calculates the periodic payment for a loan with a fixed interest rate and term length PMT has three required arguments: – Interest rate (rate) – Number of periods (nper) – Present value (pv) 29 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

30 30 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

31 A range name is a word or string of characters assigned to one or more cells Range names make formulas easier to read 31 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

32 Range names use the following rules: – 1 to 255 characters – Begin with a letter or underscore (_) – Contain letters, digits, periods, underscores Valid names include Rate, Tax_Rate, Rate_ Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

33 Excel offers a variety of methods to enter a range name after selecting the cells: – Type the range name in the Name Box area – Enter the name using New Name dialog box 33 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

34 Use the Name Manager dialog box to edit or delete a range name 34 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.

35 In this chapter, you have learned to write formulas using relative, absolute, and mixed cell references as well as correcting circular references and inserting functions. You have learned about statistical and date functions, such as SUM, AVERAGE, and TODAY. You have explored the IF, VLOOKUP, and PMT functions. You learned to create and use range names. 35 Copyright © 2014 Pearson Education, Inc. Publishing as Prentice Hall.
