1 Section 7: Spreadsheets Check your progress 1 1. Explain the difference between a spreadsheet and a worksheet. A spreadsheet file contains at least one or more worksheets. A worksheet is a single page in a spreadsheet file. 2. List the cells in the range A2:B3. A2, A3, B2, B3 3. In which row and which column does the cell P64 lie? Row 64, column P 4. What character must always be used when a formula is entered into a cell? = (equals sign) 5. Suppose that you want to enter the value 2010 as a label in a cell. How would you do this to avoid it being used in a calculation? a. Insert a single quotation in front of it, e.g Check your progress 2 Consider the following worksheet that is used to compute the monthly payroll of an organisation. A B C D E F G 1 Employee Salary Allowance Gross Pay Medical Tax Net Pay 2 Lawrence Karen Seeram Khemraj Mohan Note: a. Gross Pay = Salary + allowance b. Medical is 5% of salary c. Tax is 33% of (gross pay 35000) d. Net Pay = gross pay (Medical + Tax) 1. Indicate the cell and the formula to compute the gross pay for Khemraj. = sum(b5:c5) or = B5+C5 2. Write the formulae that you are going to need to compute the tax paid by Lawrence. (Hint: there will be a formula in D2 for Gross Pay. The formula for tax in F2 will use the result in D2.) =.35 *(D ) 3. Write the formula to compute the medical paid by Seeram. =B4* Indicate the cell and the formulae required in order to compute the net pay for Karen. Cell G2. Formula = D2 (E2+F2) 5. Write the formula to compute the total tax paid by all the employees. =sum(f2:f6) 1

2 6. Create the worksheet in Excel and enter all the formulae in this exercise. Employee Salary Allowance Gross Pay Medical Tax Net Pay Lawrence Karen Seeram Khemraj Mohan Employee Salary Allowance Gross Pay Medical Tax Net Pay Lawrence =B2+C2 =0.05*B2 =0.33*(D ) =D2-(E2+F2) Karen =B3+C3 =0.05*B3 =0.33*(D ) =D3-(E3+F3) Seeram =B4+C4 =0.05*B4 =0.33*(D ) =D4-(E4+F4) Khemraj =B5+C5 =0.05*B5 =0.33*(D ) =D5-(E5+F5) Mohan =B6+C6 =0.05*B6 =0.33*(D ) =D6-(E6+F6) Check your progress 3 Consider the following worksheet: A B C 1 Student Mark Status 2 Mohan 65 3 Khemraj 72 4 Triko 45 5 Adrial 35 6 Jones Write the function to find the Maximum marks obtain by a student. = Max(B2:B6) 2. A student is given a status PASS if his mark is over 60; else he is awarded a status of FAIL. Write the function you would insert in cell C2 to display the status. =IF(B2>60, PASS, FAIL ) 3. Write the function to find the average marks for the class. =AVERAGE(B2:B6) 4. The function =TODAY() is entered into cell C10. What will be displayed in C10? Today s date will be displayed. Check your progress 4 1. In a new worksheet, cell E3 has the formula = SUM (B3:D3). If this formula is copied to cell E10, what formula would appear in cell E10? 2

3 =Sum (B10:E10) 2. Cell E5 has the formula, = C5+$D$5. If this formula is copied to cell E10, what formula would be displayed in E10? =C10+$D$5 Check your progress 5 1. You have scrolled down your worksheet and noticed that the headings of your columns have disappeared. What can you do to make the headings of your columns visible at all times? Lock the column title. 2. Give a scenario where you would apply a title locking on both a row and column. When you need to view both row titles and column titles in a very long spreadsheet. Check your progress 6 Consider the following worksheet. 1. What would happen if you sorted the worksheet with Status as the primary sort field in descending order and Salary as the secondary sort field in ascending order? The spreadsheet will be sorted by the Status field in descending order first and then by Salary in ascending order. So the status will be arranged in order starting with technician and the salary of each technician, then network engineers will be arranged in order with their smallest value first. 3

4 2. Set up the worksheet in Excel and see if your answers were correct. Staff Status Salary(US$) Yogesh Technician 250 Ramnarine Technician 325 Ron Technician 350 Adrial Technician 400 Mohan Network Engineer 750 Gregory Network Engineer 800 Paul Network Engineer 850 Khemraj Network Engineer 950 Check your progress 7 A B C 1 2 Allan Male Mary Female Peter Male Triko Female Mohan Male Susan Female Vick Male Tota Male Amrita Female Add further data to your existing worksheet to match the table above. 2. Filter the data to find all male employees who are over 25 years and who earn more that 5000 in salary. Allan Male Mary Female Peter Male Triko Female Mohan Male Susan Female Vick Male Tota Male Amrita Female male >5000 >25 4

5 Allan Male Mohan Male Vick Male Find all employees who are Female or who earn less than 5000 in salary. Allan Male Mary Female Peter Male Triko Female bb Mohan Male Susan Female Vick Male Tota Male Amrita Female Female <5000 Mary Female Susan Female Check your progress 8 The number of registered IPv6 addresses by country is given in the worksheet below: Country Country Code IPv6 addresses Germany DE 9500 Japan JP 8300 Australia AU 8210 United Kingdom UK 1200 United States of America US 1100 In a new worksheet, create a pie chart to show the number of IPv6 addresses registered by each country. The pie chart should have the title, IPv6 Addresses by Country. Each slice of the pie chart should be properly labeled to indicate the country it represents or a legend should be provided. Each slice of the pie chart should indicate the percentage of total IPv6 addresses registered. 5

6 IPv6 Addresses by Country 4% 4% 29% 34% Germany Japan Australia United Kingdom United States of America 29% Check your progress 9 1. Create a spreadsheet and name it College.xls. This spreadsheet should have two worksheets named Student and Fees. The Student worksheet is given below: Surname First name Sex Department Credits Singh Mohan M Computer Science 32 James Allan M Mathematics 20 Monroe Mary F History 28 Ally Miriam F Sociology 24 White Michael M Chemistry The Fees worksheet should have the same data as the Student worksheet but without the Sex and Department columns. Use the link formula to copy the relevant data from the Student worksheet. Add a column to the Fees worksheet with the heading Tuition and compute the tuition paid by each student. The tuition paid by each student is obtained by the formula, Tuition = credits * In a blank area of the worksheet, enter the following data in different cells of the same column: Total Tuition Maximum credits Minimum Tuition Enter the appropriate formulae in the cells to the right of the new text above to perform the computation. 6
