Use the AutoFilter command to display selected records in a list
Describe the options in the Page Setup command used with large worksheets

**4. **Exploring Office 2003 - Grauer and Barber 4 Case Study: Vacation Time In this case study, students are asked to complete a worksheet that was started by someone else. The worksheet contains information about employees. They need to use date arithmetic to calculate how long an employee has been working here, use the VLOOKUP and IF functions to make determinations on how much vacation time each employee is entitled to and if he or she has any time left. After using these functions, students create some simple statistics, using built-in statistical functions.

**5. **Exploring Office 2003 - Grauer and Barber 5 Using Functions Function – a predefined computational task
Requires arguments
Values the function uses to calculate answers
Returns a value

**6. **Exploring Office 2003 - Grauer and Barber 6 The PMT Function Calculates a periodic payment, such as a car or mortgage payment
Based on:
Amount financed
Interest rate
Number of periods

**7. **Exploring Office 2003 - Grauer and Barber 7 Using the PMT function With the payment function, we have to make sure all arguments are expressed in the same time interval. We normally express interest rates and the length of the loan in years, while we calculate a monthly payment. Since the interest rate is expressed in years and we want the interest rate per period, divide the interest rate by 12. Since the repayment period is expressed in years and we make 12 payments per year, we need to multiply the number of years by 12.
In order for the payment amount to be positive, the amount of the loan must be expressed as a negative. Since we don’t want cell B4 to read -$9,999, we place the negative operator before the cell reference to B4 in the formula. You could also put the negative operator right after the equal sign.
If you have students who are business majors, this is no different than any time value of money calculation (present value, NPV, IRR, etc.)With the payment function, we have to make sure all arguments are expressed in the same time interval.

**8. **Exploring Office 2003 - Grauer and Barber 8 The FV function Returns the future value of a series of payments
For example, contributions to your 401K or IRA
Based on:
Number of periods
Expected rate of return
Amount invested each period

**9. **Exploring Office 2003 - Grauer and Barber 9 Using the FV Function Unlike the PMT function, in this case, all three assumptions were measured in years, so there was no need to express all the terms in months. If you wanted to illustrate the power of compounding, show the value of making a $250 contribution each month rather than a $3,000 contribution each year. Over the same 40 years, with the same 7% return, the future value would be $656,203.35. While that may not have anything to do with Excel, it is a valuable lesson for the students to learn now.Unlike the PMT function, in this case, all three assumptions were measured in years, so there was no need to express all the terms in months.

**10. **Exploring Office 2003 - Grauer and Barber 10 Inserting a Function Use the Insert Function command from the Insert menu
Use the list box to select the name of the function
Functions are categorized
Let the Wizard help you enter the arguments
Point to enter cell references
Use the Collapse button to collapse the dialog box

**11. **Exploring Office 2003 - Grauer and Barber 11 The Function Wizard Notice the formula bar as each argument is entered. As arguments are changed, the value that will be returned by the function changes. Have students examine that value and perform a reasonableness check before clicking the OK button.Notice the formula bar as each argument is entered.

**12. **Exploring Office 2003 - Grauer and Barber 12 The Goal Seek Command Allows you to set an end result and vary the inputs (assumptions) to produce that result
Only one input can be varied at a time
All other assumptions remain constant
For example, set a desired monthly car payment
Vary the amount financed
Interest rate and number of months remain the same Goal Seek can be a useful tool when one of our input parameters is inflexible. In the example given, we can’t afford more than a $200 monthly payment, so this command can be used to determine the most we can finance. Since the amount financed is contingent upon either the price of the car, the down payment, or the amount of the rebate, we will use Goal Seek to set one of those variables.Goal Seek can be a useful tool when one of our input parameters is inflexible.

**13. **Exploring Office 2003 - Grauer and Barber 13 Using the Goal Seek Command In this case, we have a maximum monthly payment of $200. We can change any one of the assumptions. For the Goal Seek command to be usable, focus on the assumptions you can realistically change. Students aren’t likely to get one of those 0% financing deals or a seven or eight year repayment period and they probably can’t negotiate the amount of the manufacturer’s rebate, so they need to be willing and able to change the purchase price of the car or the down payment.In this case, we have a maximum monthly payment of $200.

**15. **Exploring Office 2003 - Grauer and Barber 15 Developing Proficiency Use relative and absolute references correctly
Use relative cell references if the value will change when a cell is copied
Use absolute references if the value remains constant (typically assumptions)
Mixed references
Use when either the row or the column will change
Isolate your assumptions
Formulas in cells refer to the assumptions area, not to the actual values This is a review of material covered in chapters 1 and 2.This is a review of material covered in chapters 1 and 2.

**16. **Exploring Office 2003 - Grauer and Barber 16 Using Mixed References Mixed references are most often used to create a table, where one value in a formula remains the same as the formula is copied over a column, but changes as the formula is copied down a row, and the other value in a formula does just the opposite.
In the example above, when the formula in cell C6 is copied to other columns, the number of payments will always come from column B, so that column reference needs to be absolute. When it is copied to other rows, the number of payments will come from the row the formula is being copied to, so the row reference needs to be relative.
The reference for the expected rate of return is just the opposite. As the formula in cell C6 is copied to other columns, the expected rate of return will reflect the column the cell is being copied to, so the column reference needs to be relative. As the cell is copied to other rows, the rate of return will always come from row 5, so the row reference needs to be absolute.Mixed references are most often used to create a table, where one value in a formula remains the same as the formula is copied over a column, but changes as the formula is copied down a row, and the other value in a formula does just the opposite.

**18. **Exploring Office 2003 - Grauer and Barber 18 Statistical Functions MAX, MIN, and AVERAGE functions
Return highest, lowest, and average values from an argument list
Argument list may include cell references, cell ranges, values, functions, or formulas
Cells that are empty or contain text are not included
COUNT and COUNTA functions
COUNT returns number of cells containing numeric entries or formulas that return a number
COUNTA also includes cells with text It is important to note that as far as Excel is concerned, a 0 is not a blank cell, so the 0 will be included in the MAX, MIN, and AVERAGE functions. If you had two ranges of four cells, one of which contained 100, 100, 100, and a blank space and the other of which contained 100, 100, 100, and 0, the AVERAGE function would return 100 for the first range and 75 for the second. This sometimes causes havoc with students and with professors who use Excel for their grade books!It is important to note that as far as Excel is concerned, a 0 is not a blank cell, so the 0 will be included in the MAX, MIN, and AVERAGE functions.

**19. **Exploring Office 2003 - Grauer and Barber 19 Using Functions versus Formulas In general, use functions instead of formulas
Functions are adjusted as rows or columns are deleted or added within the range referenced by the function
With formulas
Adding a row adjusts the cell references in the formula, but does not include the new row in the formula
Deleting a row causes a #REF error message Study Figure 4.11 in the text, which compares the effects of inserting and deleting rows with functions as opposed to formulas. When students see the #REF error message, they typically think something is wrong with the computer.Study Figure 4.11 in the text, which compares the effects of inserting and deleting rows with functions as opposed to formulas.

**20. **Exploring Office 2003 - Grauer and Barber 20 The IF Function Enables decision making in a worksheet
Requires three arguments:
A condition
A value if the condition is true
A value if the condition is false
Condition must be able to be evaluated as true or false
Uses relational operators (=, <, etc.)
Students usually do pretty well with the conditional test. The most common mistake they make is entering another conditional test in the value-if-true or value-if-false argument, which returns either true or false rather than the value and often causes a circular reference.Students usually do pretty well with the conditional test.

**21. **Exploring Office 2003 - Grauer and Barber 21 Using the IF Function Incorrectly In this example, I have entered the value_if_true and value_if_false as conditional tests. This seems perfectly logical because, in my mind, I am saying that if the condition is true, then cell F4 will be equal to 40 and if it is false, it will be equal to the value in cell B11. The presence of the relational operator (the equal sign) causes Excel to return either True or False, rather than the value.In this example, I have entered the value_if_true and value_if_false as conditional tests.

**22. **Exploring Office 2003 - Grauer and Barber 22 Using the IF Function Correctly As illustrated here, the value can be either a numeric value or a cell reference. If you were in a union environment or thought that federal employment law regarding overtime might change, you could include the overtime threshold as an assumption and refer to that cell in the formula.
For values that are extremely static, such as an overtime threshold, it is more efficient, in terms of using computer resources, to enter the value as a value rather than a reference.

**23. **Exploring Office 2003 - Grauer and Barber 23 The VLOOKUP function Allows Excel to look up a value in a table and return a related value
Requires three arguments:
the numeric value (or cell) to look up
the range of the table
the column number containing the value you want to return
The function will look for the value in the first column of the table array, so when students are defining the table, they need to make sure the column containing the breakpoints is the first column in the table.
If the cell containing the VLOOKUP function is going to be copied, the table array needs to be an absolute reference. It might be helpful to teach the students how to define a name for the table. If they name the table and use that name in the function, it will automatically be an absolute reference.

**24. **Exploring Office 2003 - Grauer and Barber 24 Using the VLOOKUP Function A common mistake is to enter the actual column containing the result as the col_index_num, rather than the index number. For example, they would enter J, since the grades are found in column J. The function looks at the column’s position within the table array, rather than the absolute column reference.
If any of your students have had a programming class, they are accustomed to arrays beginning with 0. In this case, the array begins with 1; that is, the column containing the lookup values is 1, not 0.A common mistake is to enter the actual column containing the result as the col_index_num, rather than the index number.
