22  Design a spreadsheet that could be used to track the performance of each stock in your portfolio.  You want to record each stock’s NYSE ID, purchase price and quarterly closing price for one year. (That means four closing prices.)  At the completion of the year, you want to calculate the change in price for each stock.  You want to identify the highest priced stock in your portfolio as well as the stock that performed the best over the year.

23  STEP 1: What are the data items you will need to include in your spreadsheet?  STEP 2: Should each stock be a row or a column?  STEP 3: Where do the calculated items fit in?

24  What are the data items you will need to include in your spreadsheet?

25  Should each stock be listed as a row or a column?

26  Where do the calculated items fit in your previous layout?

27  Design a workbook that could help you calculate your overall GPA for the current semester. ◦ Try to achieve the Simplicity goal.

28  Each letter grade is assigned a weight ◦ A is weighted with a 4 ◦ B is weighted with a 3 ◦ C is weighted with a 2 ◦ D is weighted with a 1 ◦ F is weighted with a 0

29  That weight is multiplied by the credit hours for the course ◦ A three credit course in which you earn an A is weighted 12 (3 credits x weight of 4) ◦ A three credit course in which you earn a D is weighted 3 (3 credits x weight of 1) ◦ A two credit course in which you earn an A is weighted 8 (2 credits x weight of 4)

30  These weighted credits are divided by Total number of credits completed to determine GPA  BIS course is worth 3 credits earned A = 12 weighted credit hours  LIT course is worth 3 credits earned C = 6 weighted credit hours  Total weighted credit hours = 18 divided by Total number of credits completed = 6 yields a GPA of 3.0

31  STEP 1: What are the data items you will need to include in your spreadsheet?  STEP 2: Should each class be a row or a column?  STEP 3: Where do the calculated items fit in?

32  What are the data items you will need to include in your spreadsheet?

33 Should each class be listed as a row or a column?

34  Where do the calculated items fit into your prevous layout?
