ITEC1010 Assignment #2 – Excel Spreadsheets
Due: August 2, 10 PM
This is a MS Excel assignment. The software is freely available as part of the Office 365 package for students. Download and install to your system if you have not done so already.
Be sure to aim for appropriate formulas and functions that are flexible, elegant and optimally
comprehensible/meaningful as discussed in lectures.
Problem solutions must make full use of defined name ranges using the labels indicated for each cell/range. Excepting Problem 6: Forecasting, cell addresses should not be used in the
Solve each assignment problem below by following the 5-step problem-solving strategies below:
STEP 1: Understand the problem clearly — read the problem instruction carefully more than once.
STEP 2: Strategize — begin by thinking roughly as to how the problem can be solved — write your ideas out in words.
STEP 3: Design solutions– write a more structured algorithm or draw a flow chart of the ordered set of
steps required to solve the problem.
STEP 4: Implementation — translate your design algorithm to formulae that Excel can execute — use appropriate functions and name-defined cell ranges for full credit.
STEP 5: Verification — ensure that the results of your formulae match the example values.
MAIN TASK: READ CAREFULLY BEFORE PROCEDING
- Create one Excel Workbook containing separate worksheets to each of the problems below.
- Save the workbook as your full name, e.g., diana_prince.xlsx (all lowercase). Be sure to save your workbook as a normal Excel workbook file with .xlsx extension.
- Each problem must be solved in its own worksheet within one workbook so rename each sheet tab with the specific problem title, e.g., Mortgage, Invoice, etc. (Ensure to keep everything compact so that they are easily viewable when opened.)
- You may use the raw data as provided in the examples and supplementary files to test your solutions.
- Be sure to include all required components in appropriate format for each problem solution.
- Always remember that up to 50% penalty will be applied for not using named ranges optimally.
Important note about named ranges in Office 365: Due some new features added to Excel, named references may result in #N/A errors. If these are returned because of names in your formulae, begin the named reference with an ‘at’ sign (@), e.g., @SALES instead of just SALES.
Problem 1: Mortgage
- Duplicate the Mortgage Calculator model below in your Excel worksheet.
- Formulae for cells F4 to F7 are as per Figure 1.
- Name all appropriate cells using their labels and reconstruct the formulae replacing cell address references.
- Test by entering assumption inputs to cells C4 to C7 using input examples in Figure 2.
- Now reconstruct the summary table (as per Figure 2 – B9:E11) and populate cells with
appropriate labels and named references.
- Format the whole model as per Figure 2 including:
a. Model title font set to 12pts and merge-centered (B2:F2)
b. “Initial Assumptions” and “Result” merge-centered across 2 columns with Thick Outside
Borders; other data with All Borders
c. Summary table labels with Thick Bottom Borders
d. Format values appropriately as Number, Currency, or Percentage e. Color fill areas with 3 different colors of your choice
f. Bold face displayed data
Problem 2: Staff Payroll
Re-create the Staff Payroll model below for weekly pay calculations with the format and features shown in Figure 3.
• Range names should correspond to their respective labels.
• Calculating the Total_Pay (column J) involves applying the following rules: hours worked amount that is 37 or less is calculated by multiplying it and the standard hourly rate; beyond that any extra hours up to 10 hours are calculated at time-and-half, or 50% more than the standard hourly rate; and hours logged greater than 47 are calculated at double-time, or 100% higher than the hourly rate.
Key functions to use: IF and ISNUMBER;
Problem 3: Movies
Re-create the model below that search the Top IMDB Rated Movies table and returns the attributes of the Rank holding movie.
• Download database file Top10Movies.csv and import into your workbook (Figure 4).
• The model works by having the user enter the rank # and Excel returns the details stored in the database table. Figure 5: Rank # 8 is entered by the user and Excel returns the related Info data.
• Use the rank number input as the lookup value for VLOOKUP.
• The solution should be a single ‘master’ formula that would work for any attribute i.e., the formula that returns the correct Title in the searcher Info is appropriate for being Auto-Filled
down the column to return the rest of the movie attributes in the Database.
Key functions to use: VLOOKUP; MATCH
