Spreadsheet

A Spreadsheet is any document with a grid of

columns and rows. For centuries, managers

have used papers that was lined with columns

and rows for their computations.

Spreadsheet is a document prepared with

columns and rows used for data entry and

computation which is done manually or

electronically;

Electronic Spreadsheet Electronic Spreadsheet is software designed with a grid of columns and rows

often called cells upon which data are entered and computed automatically

with the help of formulas.

A Electronic spreadsheet is an interactive computer application program for

organization, analysis and storage of data in tabular form. Spreadsheets are

developed as computerized simulations of paper accounting worksheets.

The program operates on data represented as cells of an array, organized in

rows and columns.

However, electronic spreadsheet required managers to be computer literate

in order to use electronic spreadsheet successfully.

Implication of Electronic Spreadsheet to a 21Implication of Electronic Spreadsheet to a 21stst Century Teachers’ Century Teachers’

Computer generally classified under education as an educational

tool which assist in teaching and learning; therefore excel as a

computer programme has a very vital role to play in assisting

teachers in data processing and storage, the following are the basic

areas in which excel assist teacher:

1.Data Storage

2.Students’ Result Computation

3.Planning

4.Time Management

Data Storage Data Storage Microsoft excel helps teacher in keeping students’ data e.g.

Students Performance

Students’ Result Computation Students’ Result Computation Microsoft excel helps teacher in computing students’ Continuous Assessment (CA and Exams)

•It help teacher in entry and calculating students’ performance by using formulas that will make the calculations to automatic

•Lets refer to the slide five

Planning /BudgetingPlanning /BudgetingMicrosoft excel helps teachers’ in planning their

activities as well as budgeting especially:

Academic Calendar: e.g. Teaching Time-Table

planning; Planning students activities within and

outside class, Scheduling for CA and Examinations and

planning examination time-table as well.

Time-Management Time-Management Microsoft excel helps teachers in maintain time; e.g. if a

teacher can computes student’s result in 15minutes

manually then it can only takes him 5 minutes

electronically.

Disadvantages of Electronic SpreadsheetDisadvantages of Electronic Spreadsheet

A teacher must be computer literate before using excel,

Data might be lost due to improper saving or system damage

Solutions to the above problems:

1.Teachers must be train on the use of computer and excel programmes

2.Teachers using electronic spreadsheet must use backup devices e.g. google

drive, OneDrive and External storage devices like: flash disk, hard disk etc.

and also after data have being inputted and processed it should be printed on

hardcopy for documentation

Instances of Electronic Spreadsheets

Excel

Excel: is a software design and produced by Microsoft

cooperation; which is often called Microsoft Excel, the

packages is embedded in Microsoft Office and thus has

different versions: ranges from:

Microsoft Excel 2003

Microsoft Excel 2007

Microsoft Excel 2010

Microsoft Excel 2013

Microsoft Excel 2016 which is the latest

Excel Interface Excel Interface

Excel interface is like any other application in computer, it is

referred to as an environment where user interact with the

computer through which computer operations are being carried

out, the application’s environment serve as a medium to which user

communicate with computer by selecting commands or entering

the commands like figures in text fields.

Excel as an application that computes data, it has a unique

interface than other applications. As shown in the diagram below.

A CellA Cell Cell is an intersection of row and column, which is

use for entering data and formulas for calculation

purposes. A cell has its name from the number of

column A. B. C… and number of rows 1. 2. 3… e.g.

A1 means intersection of column A and Row 1, thus

often called cell reference. See below diagram

B2 Is a cell reference of Column B and Row 2, cell reference usually displayed in a name box and content of that cell will display in formula bar.

There are three types of cell reference:1. Absolute, 2. Relative and 3. Mixed referencing. Read more (http://www.howtogeek.com/school/microsoft-excel-formulas-and-functions/lesson3/)

What is the functions of cell reference, cell reference can be use:

1. To locate a cell faster,

2. To input formulas within and outside the worksheet, and

3. To refer to a certain data that could be found on a data for calculations.

What is an Active Cell? Refers to as any cell which its name displayed in a

name box and the contents of an active cell will appear

on formula bar. Thus is referred to as an active cell.

However it can be further identified by observing it

outlines are highlighted with thick and dark boundary

than other cells. The heading number of its columns

and rows will be highlighted as well.

A cell will not accept data unless it is active, to

achieve that a cell must by activated by

selecting it with the mouse pointer often called

cell selector or by using navigation keys to move

to a desired cell. If such happen then we

referred to that as an active cell.

Worksheet and Workbook

Worksheet is a interconnections of cells which were

displayed in an array of columns and rows, a worksheet

in Microsoft Excel 2016 consist of 17,179,869,184 cells.

i.e. 1048576 number of rows XFD (16,384) Number of

Columns.

Workbook is the collections of a worksheets range from

1 worksheet…..n. A Workbook may consist of 1,024 and

above worksheets.

Formula

Formula is an equation that expressed

mathematical operation on a given cell,

formulas help in carrying out automatic

calculations of data on a given cell or an

array of cells.

Mathematical Operation in Microsoft ExcelMathematical Operation in Microsoft Excel

The following are the basic signs for mathematical operations

in Microsoft Excel:

= sign is used at the begging of a formula, “= sign” define to

excel that this is a mathematical operation not a data

therefore solve the defined problem .

A1, A2, B1, C1... are cells references which is used to

define what cell the formula could refer to for mathematical

operation, cell referencing could be along columns or rows or

within the worksheet or workbook, as shown in

demonstration.

+ sign for addition

- Sign for subtraction

* sign for multiplication

/ sign for division

( ) define a collected cell like in using

standard mathematics operations, e.g.

sum, average etc.

Sheet2!A1 is to select cell A1 in Worksheet

2.

Construction of a Formula Construction of a Formula To perform calculations on a particular cell like summing cell A1

and B1 subtract cell C1. This could be express thus: = A1+B1-C1

Performing mathematical operation on a number of cells in an

array of columns or rows e.g. Cell A1 A2 A3 and A4 has different

data which were required to be sum together, thus express as:

=sum(A1:A4)

Performing mathematical operation on a number of cells which

could be found in different location within and outside the

worksheet; thus express as: =sum(A1, B10, W20) i.e. sum up data

found on Cell A1, Cell B10, and W20. automatically the formula will

locate and sum up data on Cell A1, B10 and W20 respectively.

Logical FormulasLogical Formulas

This kind of formulas express the decision making on a

cell data e.g. =if(A1=1,”True”, if(A1<>1, “False”))

That is to say if cell A1 is equal to 1 then print “True”

or/and if cell A1 is greater or less than 1 then print

“False”. In the above equation there is a great

decision making on the contents of Cell A1, the

formula reads the data in any assigned cell and it

compare with its scale of preferences to make a

decision as the output.

Word Processing Word Processing Word processing is the phrase used to describe using a

computer to create, edit, and print documents. Of all

computer applications, word processing is the most

common. To perform word processing, you need a

computer, a special program called a word processor,

and a printer. A word processor enables you to create a

document, store it electronically on a disk, display it on a

screen, modify it by entering commands and characters

from the keyboard, and print it on a printer.

In Summary In Summary

Word Processors can be used for writing,

editing, and production of documents, as

letters, reports, and books, through the

use of a computer program or a complete

computer system designed to facilitate

rapid and efficient manipulation of text.

Word Processing Compared to Using a Typewriter

The great advantage of word processing over using a typewriter

is that you can make changes without retyping the entire

document. If you make a typing mistake, you simply back up the

cursor and correct your mistake. If you want to delete a

paragraph, you simply remove it, without leaving a trace. It is

equally easy to insert a word, sentence, or paragraph in the

middle of a document. Word processors also make it easy to

move sections of text from one place to another within a

document, or between documents. When you have made all the

changes you want, you can send the file to a printer to get a

hard copy.

Microsoft Word Microsoft Word is a word processor developed by

Microsoft. It was first released in 1983 under the name

Multi-Tool Word for Xenix systems.

1.Word for DOS

2.Word for Windows 1 and 2; Word 3 and 4 for Mac OS

3.Word 5 and Word 95 for Windows; Word 6 for Mac OS

4.Word 97 and later for Windows; Word 98 and later

Microsoft Word 2016 Interface

Quick Access: is bar consist of icons which are required

as emergency e.g. Save Icons for Saving Document,

Undo for reverse by one step, Redo repeat action by

one step.

Tab bar: this is an array titles which consists a relative

sets of commands; each of the titles displays desirable

commands that reflects the titles e.g. Home Tab (just

to say Initials requirement) displays commands that

were basic in text editing: BOLD, Underline, Italic,

Fond Size, Fond List , Colour, Change CASES,

Copy and Paste, Text Align, Line Spacing etc.

Ribbon: is a partition that emanates under a given Tab,

ribbon consist a collections of commands that were

grouped (Chunk of commands) that has significant

relationship with the title of the tab as describe in item

above. All tab has different groups of commands under

them. In some application like CorelDraw: Property Bar

behave like ribbon. It changes base on the Title of a

tab.

The Ribbon consist of the following groups: clipboard,

Font, Paragraph, Style and Edit group

Title Bar: this bar designates File Name and the Name

of the application e.g. GSE 213 Lecture Note – Word,

here the File name is GSE 213 Lecture Note while Word

stands for the application’s name: but in case if the file

is not saved title bar displays only: Document1

(Compatible Mode)- Word. Thus clearly defines that the

file is not saved: (file is required to be saved)

otherwise the data might be lost if the computer was

shutdown.

Control Buttons: minimize, restore and

close: applicably minimize is to inhibit the display of the window

for desktop interface utilization, minimized application will be

active on the task bar.

Next button is restore down when the application is cover up the

screen and the same button could be maximize button it operates

in reverse order of restore down.

Close button is used total closer of the application, here files that

are not saved could be demanded to be saved, however a dialog

box will display intimidating the save, don’t save and cancel; one

of which must be chosen: for closure save and don’t save button

can be selected for not closure cancel button can be selected.

Ruler; it acts on mensuration and it consist

measurement units (distance) in inches, can be used to

set margins, paragraphs, header and footers etc.

Cursor: this indicates the readiness of the edit

environment to accept text input and text edit, the

cursor usually blinks to indicates readiness. However

cover can be used in navigation as well, when the

navigation keys were pressed the cursor will move to

the direction of any of the navigation key pressed on

the keyboard.

Text Edit Field: (Page) it is an environment where text

can be inputted, edited, format and print out: the page

is guided by the layout tab were different sizes of

pages can be chosen and the margins as well.

Zoom Level: this can be used to increase or decreased

the magnitude of the Text Edit Field (Page). The

positive sign is for zoom in (Increase in magnitude)

minus sign (Decrease in magnitude).

Document View: this deals with the displays of the Text

Edit Field (Page) which has three different views: Read

Mode, Print Layout, and Web Layout.

Status Bar: this bar displays information on a

document: e.g. number of words in the document,

number of pages in the document.
