## MSCI 242 Spreadsheet Modelling for Management

OPEN BOOK EXAMINATION  (1.5 HOURS)

This exam contains three sections. You must answer all of the questions in each section.

Section A contains short questions, and is worth 25% of the total marks.

Section B contains longer questions, and is worth 50% of the total marks.

Section C contains a single question worth 25% of the total marks

### SECTION A (25% of marks) – Excel Functions and Formulas电子表格建模代写

Use the dataset below for Sections A, B and C

The dataset you will analyse is sales data for 7 products, over a period of one calendar year.

The 7 product codes are as follows: A-18/C4, A-18/C5, A-18/C6, A-18/C7, A-18/C8, B-18/C9, B-18/C10

Each month’s sales data is held on their own, separate sheet.

The structure of the data is identical on each sheet except that some months have more days than others.

The 12 sheet names are as follows: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov and Dec

Below is a screenshot of the sheet for February’s sales.

Note: day 11 through to day 24 have been hidden in the screenshot above, for presentation purposes.

Column A contains the day of the month number: 1 to 28 for this month, as there are 28 days in February.

Column B contains the day of the year number: January has 31 days, so February is 32 through to 59.

Column C denotes whether the day is a weekend day: 1 = Saturday or Sunday. All other weekdays are 0.

Columns D through to J are the number of units sold for each of the 7 products.

For example, on day 1 of February, 65 units of product A-18/C4 were sold. On day 2, 74, and so on.

• total monthly sales for each product, in cells D2:J2

• average monthly sales for each product, in cells D3:J3

• maximum number of units sold that month, for each product, in cells D4:J4

• total sales for each day, across all 7 products, in column L  [e.g. day 1 is 653 units]

• total sales for the whole month, in cell L2  [20,002 units]

• average daily sales, across all 7 products, in cell L3  [714.36 units per day]

• maximum daily sales, across all 7 products, in cell L4  [829 on day 26]

### SECTION B (50% of marks) – Excel Model Development电子表格建模代写

The following section is multiple choice. Submit one answer to each question.

The following summary table has been constructed on a sheet called Summary to present the number of units sold for each product, for every month of the year.

In addition to this summary table, a Data Address Matrix has been created on the same Summary sheet to store the addresses for the each month’s sales data, for each of the 7 products:

An additional column O has been added to the summary table, to extract the data for a dynamic chart, based on a numerical choice inputted by the user in cell O4.

Cell O4 has been named chart_choice and currently contains a 1, and thus will extract the data for the 1st of the seven products (A-18/C4).

Cell J4 contains the text that will be used for the chart’s dynamic title.

#### Question 17

B: = INDEX(F6:L6,chart_choice)

C: = INDEX(F7:L7,”chart_choice”)

D: = IF(chart_choice=1,F7,IF(chart_choice=2,G7,IF(chart_choice=3,H7,IF(chart_choice=4,I7,

IF(chart_choice=5,J7,IF(chart_choice=6,K7,L7)))))

E: = INDEX(F7:L7,chart_choose)

F: = INDEX(F7:L7,O4)

G: none of the above

(5 marks)

#### Question 18

What is the formula in cell J4, to create a dynamic title for the chart?

A macro has been created which compiles all 12 months data onto a single data sheet, called All Data!

A screenshot of this compiled datastack is given below.

### SECTION C (25% of marks) – VBA电子表格建模代写

Question 21

As mentioned previously, a macro has been created to compile all 12 months data onto a single data sheet called All Data!

The macro is presented below. The macro copies and pastes each month’s sales data onto the All Data sheet, and the month name is added to column A to create the datastack shown on the previous page.

A message box is shown at the end to inform the user of a successful compilation.

However, the macro has some mistakes in the code, which will cause the macro to either crash, or not compile the data correctly.

Identify 5 separate mistakes and for each ‘mistake’:

• Identify the line of code by number (1 – 24)

• Describe the mistake

• Provide the correct version of the code, or describe the solution to the mistake

Note: a line may contain more than one mistake.

Note: only the first 5 mistakes presented will be marked. Any other mistakes presented will be ignored. (25 marks)
