2. A.Penjira (Mony) Kanthawongs2 Class 9 Agenda  Turn in Ind. HW and Group HW  Lecture Excel P.2 Page E 2.23 – E 2.64  Lab Test # 2, Excel Project 1 and Excel Project 2  Do not forget!, in Class 10, Present your group HW. (Each group need to make the draw for the order of your presentation.)

3. A.Penjira (Mony) Kanthawongs3 Scores for Group Homework E.1  Full points for each Excel 1 & Excel 2 is worth 7.5 points.  The group presentation for Excel 1 and Excel 2 is worth 15 points. (Present on Class 10) –5 points for well- prepared speaker. –5 points for well-prepared equipments for presentation. –5 points for problem solving, question answering, and teamwork.  Total of Group Homework Excel : 30 points.

4. A.Penjira (Mony) Kanthawongs4 How to do the presentation on Class 10? –You can present your Excel document(s) with the computer in front of the class, show the printout(s) of the documents and talk about it(them), or use PowerPoint program. –Each group has only 8 minutes to make the presentation. –Come early, if the group does not show up on time  0 point

5. A.Penjira (Mony) Kanthawongs5 Content for your presentation  When you present your Excel, you need to... –Explain the meaning of your data (i.e. what the columns and the rows of your data represent?, what is your business?) –Explain about the meaning of your Average, Max, and Min....(i.e. which products sell the most?)

6. A.Penjira (Mony) Kanthawongs6 Using the AVERAGE, MAX, and MIN Functions  Excel includes prewritten formulas called functions to help you compute these statistics.  The values that you use with a function are called arguments.  All functions begin with an equal sign and include the arguments in parentheses after the function name. =AVERAGE(D3:D 10) Function Name is AVERAGE Argument is the range D3:D10

7. A.Penjira (Mony) Kanthawongs7  The AVERAGE Function –...the statistical functions ignore blank cells. Thus, in Excel, the ave. of three cells with values of 2, blank, and 4 is 3 or (2+4)/2, and not 2 or (2+0+4)/3 (Page 2.16 Orange Box)  The AVERAGE Function –sums the numbers in the specified range and then divides the sum by the number of non- zero non-blank cells in the range.

8. A.Penjira (Mony) Kanthawongs8 6. Use the AVERAGE function to determine the average for the # of Shares, Initial Price per share, Initial Stock Cost, Current Stock Price, Current Stock Value, and Gain/Loss for each stock.

9. A.Penjira (Mony) Kanthawongs9 Using the Keyboard and Mouse Enter Box

10. A.Penjira (Mony) Kanthawongs10 Using the Edit Formula Box and Functions Box  Select the position | Click “the Edit Formula Box” | Click the “Functions box arrow” and then point to MAX Functions Box Edit Formula Box

11. A.Penjira (Mony) Kanthawongs11 Name Box changes to Functions Box Formula Palette displays

12. A.Penjira (Mony) Kanthawongs12 Click MAX | Type the range or Use the Point Mode | Click OK

13. A.Penjira (Mony) Kanthawongs13 Click OK

14. A.Penjira (Mony) Kanthawongs14 Using the Paste Function Button to find MIN

15. A.Penjira (Mony) Kanthawongs15 Use the Fill Handle to copy and Delete the invalid cell The AVERAGE of the percentage of gain/loss is mathematically invalid.

16. A.Penjira (Mony) Kanthawongs16 Verifying Formulas  The wrong cell reference in a formula is the most common mistakes made with Excel.  To avoid the mistakes, Excel has 2 methods…

17. A.Penjira (Mony) Kanthawongs17 Auditing Commands Range Finder Trace Precedents Trace Dependents 2 methods to verify formulas

18. A.Penjira (Mony) Kanthawongs18 To Use Verifying Formulas  To Use Auditing Commands –Go to “Tools” | Choose “Auditing” | and choose “Trace Precedents” or “Trace Dependents” or “Remove All Arrows”  To Use Range Finder –Select the cell | Press “F2” at the keyboard or Double-Click the cell.

19. A.Penjira (Mony) Kanthawongs19 Trace Precedents Command  Highlights the cells in the worksheet that are referenced by the formula in the active cell.  the Formula in the Active Cell + Referenced cells Tracer Arrows Arrowhead

20. A.Penjira (Mony) Kanthawongs20 Trace Dependents Command  Highlights the cells with formulas in the worksheet that reference the active cell.  the Active Cell + the Cells With Formulas Circle at the beginning Arrowhead

21. A.Penjira (Mony) Kanthawongs21 Range Finder  Can be used to check which cells are being referenced in the formula assigned to the active cell.  the Formula in the Active Cell + Referenced cells 80015.875=D3*E3

22. A.Penjira (Mony) Kanthawongs22  Range Finder command is similar to the Trace Precedents command, but Range Finder command allows you to make immediate changes to the cells referenced in the a formula.

23. A.Penjira (Mony) Kanthawongs23 Conclusion  The Auditing Commands (Trace Precedent and Trace Dependent) are used to verify the correct cells.  Range Finder is used to verify the correct cells and make immediate changes.

24. A.Penjira (Mony) Kanthawongs24 Choosing Colors  Warmer colors (Red and Orange) --> reach the reader.  Cooler colors (blue, green, and violet) --> pull away from the reader.  Bright colors jump out of the dark background --> easy to read.  White or yellow text on a dark blue, green, purple, or back background is ideal.

27. A.Penjira (Mony) Kanthawongs27  Use Increase Decimal Button to increase the decimals.  Use Decrease Decimal Button to decrease the decimals.  Use Percent Style Button to get Percent Style Format.  Important Note: Although Percent Style Format displays only 2 decimals, Excel does maintain all the decimal places for computational purposes.

28. A.Penjira (Mony) Kanthawongs28 Conditional Formatting  Conditional Formatting Command  Cell Value is Less Than O condition value 2 relational operator value 1

29. A.Penjira (Mony) Kanthawongs29  Condition --> made up of 2 values + a relational operator.  Relational operator --> If..true..Excel applies the formatting. If..false..Excel suppresses the formatting.  Look at Page E 2.41

30. A.Penjira (Mony) Kanthawongs30 Conditional Formatting Dialog Box Value 1 Relational operator Value 1

31. A.Penjira (Mony) Kanthawongs31  Use Format Painter Button to copy format(s) of cell(s) to other cell(s).  A pixel is a dot on the screen that contains a color.  A screen with a resolution of 800 x 600 pixels is better than that of 400 x 300 pixels.  Hiding is a technique you use to hide data.
