Presented by: Dennis Taylor

 AutoSum Button

 Select cells along right side or below data (or both) and use AutoSum button or its drop arrow functions

 Displaying Formulas and selecting formula cells

 Press Ctrl+~ to toggle between displaying formulas and displaying results

 On Home tab, click the Find&Select button, then Formulas

 Multiple cell formulas with the Ctrl key

 Select cells where similar formulas are needed

 Type one formula and press Ctrl+Enter

 Relative References - Use the F4 key

 Quickly adjust cell formulas to freeze row references, as in A$4 or column

references, as in $A4.

 Use entire Row or Column references in formulas

 =SUM(B:B) instead of SUM(B2:B655)

Power Tips

 =IF(condition,true,false)

 Conditional operators - < > = >= <= < >

 =IF(B2>=400,1000,"Sell")

 Nested, multiple IFs

 =IF(B3>5,100,IF(B3>3,50,25))

 =IF(B3>5,100,IF(B3>3,50,IF(B3>2,25,10)))

 Using AND and OR with IF

 =IF(AND(condition1,condition2,…),true,false)

 =IF(AND(B6="A",B7="B"),100,50)

 =IF(OR(condition1,condition2,…),true,false)

 =IF(OR(A3=7,D3=5),100,50)

Power Functions: the IF Function

 VLOOKUP (item to look up, table location, column number in table where

answer is found, exact indicator)

Compare the value of cell A7 with values in the left column of the range in columns P through S; locate the value nearest to (but not above) the value

in A7 and return a value found in column Q (second column of P thru S

Compare the value of cell H3 with values in the left column of the range K1:N9; when an exact match is found, return a corresponding value found

in the third column of K1:N9 If not found, return #N/A

Power Functions: the VLOOKUP Function

 ROUND – alter the results of formulas to round results to the nearest power of ten – often to two or zero decimals

 =ROUND(B3*N1+B3,2) – rounds a calculation to the nearest two decimal places

 =ROUND(B3*N1+B3,0) – rounds the calculation to the nearest whole number

 ROUNDUP – rounds up to the next level,

 =ROUNDUP(C3*D4,1) – if C3*B4 equals 7.32, changes result to 7.4

 ROUNDOWN - rounds down to the next level

 =ROUNDDOWN(F3*G4,1) – if F3*G4 equals 6.18, changes result to 6.1

 MROUND, CEILING, FLOOR – allow rounding to any value, not just powers of ten

Rounding Functions

 MAX, MIN - find highest/lowest values in a range

range

Statistical Function Overview

 =COUNTIF(E2:E90,"=Colorado") Count how many cells in the range E2:E90 equal "Colorado"

 =SUMIF(K2:K66,"=Ohio",J2:J66)

Total all values in J2:J66 when the corresponding entry in Column K equals "Ohio".

 =AVERAGEIF(K2:K66,"=Ohio",J2:J66)

Calculate average of values in range J2:J66 when corresponding entry in Column K equals "Ohio"

 =COUNTIFS(E:E,5,F:F,"=Iowa") Count how many cells in Column E = 5 and in Column F = Iowa"

 =SUMIFS(H:H,E:E,5,F:F,"Utah",G:G,">500")

Total all values in Column H when the corresponding entries in Columns E, F, and G are:

equal to 5, equal to Utah, and greater than 500, respectively.

 =AVERAGEIFS(H:H,E:E,5,F:F,"Ohio",G:G,">500")

Calculate the average of all values in Column H when the corresponding entries in Columns E, F, and

G are: equal to 5, equal to Ohio, and greater than 500, respectively.

COUNTIF and Related

Functions

 New in Excel 2010-

-AGGREGATE – tabulate data based on commonly used statistical measures (SUM,

AVERAGE, MEDIAN…) with options to ignore errors and hidden rows)

 New in Excel

2013 -ARABIC– convert Roman numerals into Arabic numbers; a companion the ROMAN function

which converts numbers from Arabic to Roman.

ISFORMULA – check whether a reference is to a cell containing a formula, and return TRUE or FALSE

can be used with Conditional Formatting to dynamically indicate which cells contain formulas

FORMULATEXT – displays the text of a formula from another cell

ISNA – check whether a value is #NA, and returns TRUE or FALSE
