3. Practice Test Take the Practice Test on Blackboard!!!! More than half of the questions will be formatted the same or similarly as the practice test, quizzes and in-class problems Take the Emerge Practice Tests Questions may have different numbers, but the same concepts Questions may be the EXACT SAME

4. In This Review Session… We will go over: Key terms/concepts in EXCEL Functions in EXCEL Practice Test Questions

5. Syntax: =AVERAGE(number1, [number2],...) Arguments: number1 Required  The first number, cell reference, or range for which you want the average. number2,... Optional  Additional numbers, cell references or ranges for which you want the average, up to a maximum of 255.

6. Description: Returns the average (arithmetic mean) of the arguments. Remarks: Arguments can either be numbers or names, ranges, or cell references that contain numbers. Logical values and text representations of numbers that you type directly into the list of arguments are counted. Errors: Arguments that are error values or text that cannot be translated into numbers cause errors.

8. Microsoft ® Excel ® Mathematical Functions Syntax: =SUM(number1, [number2], [number3], [number4],...) Arguments: number1 Required  The first item that you want to add. number2, number3, number4,... Optional  The remaining items that you want to add, up to a total of 255 items.

9. Microsoft ® Excel ® Mathematical Functions Description: Adds all the numbers that you specify as arguments. Remarks: Each argument can be a range, a cell reference, an array, a constant, a formula, or the result from another function. If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, or text in the array or reference are ignored. Errors: If any arguments are error values, or if any arguments are text that cannot be translated into numbers, Excel displays an error.

11. Absolute, Mixed and Relative For a formula being copied: If the reference is:It changes to: $A$1 (absolute column and absolute row) $A$1 (the reference is absolute) A$1 (relative column and absolute row) C$1 (the reference is mixed) $A1 (absolute column and relative row) $A3 (the reference is mixed) A1 (relative column and relative row) C3 (the reference is relative)

12. Shortcuts Cut item and store selection in the clipboard Ctrl + x Open Task Manager in Windows to see which programs are running Ctrl + Shift + Esc Paste item from clipboard into designated cell Ctrl + v Toggles between Relative, Absolute, and Mixed cell references F4 Save workbook with a *.xlsx or *.xls file extension Ctrl + s Manually recalculates worksheet, including updating date and time functions F9 Copy the active dialog box or screen image to the clipboard Alt + PrntScr Erases the last change done to the worksheet, reverting it to an older state Ctrl + z

13. PEMDAS

14. Percents 5% =.05 100%= 1 140%= 1.4 How do you find 16% of 92? =.16*92

15. Quiz Question (Excel) Assume that cell F4 in a spreadsheet has the following formula: =B$4+$C4 What formula will result from copying it into cell G5? =C$4+$C5

16. Quiz Question Which of the following should be used to refer to the cell reference AB$88? a. Invalid b. Absolute c. Mixed d. Relative e. None of the above

17. Write a formula to calculate the average speed of all drivers listed in the table. =AVERAGE(D5:D9) Quiz Question

18. Using a scale of 1 to 4 (first to last), rank each of the following operations in order of precedence: – Addition and subtraction- Exponentiation ()parenthesis Multiplication and division Addition and subtraction4 Exponentiation2 ()parenthesis1 Multiplication and division3

19. Add a range of numbers stored in cells A3 through Z3 = SUM(A3:Z3) Find the arithmetic mean of the values in cells C1 through C10, assuming any blank cells will be ignored = AVERAGE(C1:C10) Quiz Question What formula would you write to perform each of the following ?

20. Quiz Question If the formula: =C$4*$H8 is copied from cell A3 to cell D5, what formula will appear in D5? Answers: =F$4*$H10

21. Quiz Question How many unique cells are included in the array (or range) that is referenced in the following formula? =AVERAGE(B9:D14) Answers: 18 =18 eighteen

22. Quiz Question The dimensions of a storage tank for Killer Whales at SeaWorld is 50ft x 50ft x 20ft. If saltwater weighs approximately 60 pounds per cubic foot, write a formula to calculate the weight of the tank at full capacity. Answers: =50*50*20*60 =50^2*20*60 =50 * 50 * 20 * 60 =50^2 * 20 * 60

23. Quiz Question When entered into a worksheet cell, all of the following are considered to be constant values, except: A) Friend B) A9*B10 C) 210 D) CIS300

24. Quiz Question Mac and Farva need 40 liters of cola for an upcoming frat party. They notice the two grocery stores near them have drastically different prices for liters. One grocery sells liters for $1.20 per liter. Another has a sale going on, “Buy 10 Liters of Cola for only $5”. Assuming they were going to purchase all 40 at the same grocery, write a formula that would calculate the potential savings if they choose the cheaper option. =(1.20-.50) * 40 =(1.20- (5/10)) * 40

25. Helpful Hints Don’t forget an “=” when you are asked for a formula Rows VS Columns Trick Remember there are sometimes several correct ways to write the same answer! Do not ignore the Emerge content. It is a good portion of the test. Study Definitions. Retake the practice test and re-practice the homework this weekend
