IT GOVERNANCE AND DECISION MAKING

Working with the Excel Environment 

Excel allows us to calculate numerical information using formulas. In Module 2, we learn how to use cell references to create formulas. In order to create a formula, we need to learn about Excel standard operators for formulas. These operators are a plus sign (+) for addition, a minus sign (-) for subtraction, an asterisk (*) for multiplication, a forward slash (/) for division, and a caret (^) for exponents. Excel uses = sign to start a formula, and that cell must be equal to the formula which is calculated for.

Excel 2013 uses features like the Ribbon and Quick Access toolbar to perform common tasks. The Ribbon in Excel 2013 uses a tabbed Ribbon system rather the traditional menu. Below is the description of the different tabs in Excel 2010-2013.

Understanding cell references

A cell is recognized by its address. The intersection of a columns and a row represent a cell address. For instance, column B and row 3 is the cell B3. The cell value is the value of what we calculate for a specific cell. For instance, if we B1 = 15, B2 = 25, then the value of B3 = B1+B2 or B3 = 15+25=40, therefore, the value of B3 = 40 as shown below.

 

In formula section we have, Fx =A1+A2

15

25

B1+B2= 40

SLP Assignment 

Please note that SLP 2 Assignment has the following exercises and basic spreadsheet exercises from the Abacus Training site.

Use the table below to do the following.

= A1+A2+A3+A4

= B4 – B2

= C4/B2

= C3/5

A4^2

Write the cell address according above table for the following:

Gas used for June

36

 

Gas used for May

45

 

Total used gas

81

 
  1. Use the below table to calculate the total for each item; however, instead of manual work, use the formula function. For example, to calculate each item, you need to do the following.  
  • Place = on the formula bar in the Total column
  • Multiple Quantity X Unit Price in the Total column

After completing the Excel exercise above, please continue developing the Abacus Excel spreadsheet exercises located at http://triplecsa.fhost.com.au/Blog/wp-content/uploads/2013/09/Basic-Spreadsheet-Concepts-Exercises.pdf  and as noted below.

Exercise 1 - Sales for the Month

Exercise  2 - Sales and Produce Department

Exercise 3 - Mike's Stationery Order

Create an Excel file with designated folders 1-4 to develop the above exercises. 

 

SLP Assignment Expectations

The SLP should be developed in Excel. Your assignments will be graded following these expectations:

  • Precision: The questions asked are answered.
  • Clarity: Your answers are clear and show your good understanding of the topic.
  • Breadth and depth: The scope covered in your paper is directly related to the questions of the assignment and the learning objectives of the module.
  • Critical Thinking: It is important to read the “required readings” posted in the background material plus others you find relevant. Your paper should include important concepts from these readings and incorporate your reactions and examples that illustrate your reflective judgment and good understanding of the concepts
