3.  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

4.  =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

5.  VLOOKUP (item to look up, table location, column number in table where
answer is found, exact indicator)
 =VLOOKUP(A7,P:S,2) approximate lookup
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.
 =VLOOKUP(H3,K1:N9,3,0) exact lookups
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

6.  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

7.  MAX, MIN - find highest/lowest values in a range
 AVERAGE - calculate arithmetic mean of values
 MEDIAN - calculate the middle value in a values range
 MODE - calculate the most frequent occurrence in a values range
 RANK - calculate the rank of a value in a range
 LARGE, SMALL - find the nth largest or smallest value in a range

Statistical Function Overview

8.  =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

9.  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
