Q1: What is the difference between Microsoft Word and Microsoft Excel? What are the functions, advantages and disadvantages of both programs?

Differences Microsoft Excel is a spreadsheet application from Microsoft like lotus 123 and

lotus notes and its very much different from Microsoft word since Microsoft word is a word processor and Microsoft Excel is a spreadsheet that means you can make tables and charts and comparison and conditional formatting and different kind of charts and maps and others in excel very easily which are not possible in word. Moreover excel gives you a grid like view which helps a lot too.

Excel is a program for keeping records, tables, grades, charts and a thousand other uses.

Word is a program for text printing with a multitude of options. Both are completely different in applications.

Microsoft Excel is software that works mathematical equations of all kinds. Microsoft Word is software that you type letters, newspaper columns, and can do desktop publishing with it. That is making banners, letterheads and all kinds of cool stuff.

Functions, Advantages and Disadvantages Microsoft Excel is a program that is designed primarily for creating spreadsheets

that a user can use to sort and organize data into easy to understand forms. It makes this very easy by enabling users to analyze data in the forms of tables, charts, and worksheets.Here is a summary of the main purposes of the program: >Understanding the practicality of Microsoft Excel familiarizing oneself with Excel's basic feature >Using spreadsheets in everyday activity to understand complicated data >Using constants and formulas to create a faster way to input data

Microsoft Word is a program that is designed primarily for word processing.

Q2: What are the differences between a cell, worksheet and a workbook? How to color code sheet tabs to make it easier to be recognized? How to view different parts of a worksheet at the same time? How to view different worksheets at the same time?

Differences

CELL WORKSHEET WORKBOOKIn a spreadsheet the CELL is defined as the space where a specified row and column intersect. Each CELL is assigned a name according to its COLUMN letter and ROW number.

In the above diagram the CELL labeled B6 is highlighted. When referencing a cell, you should put the column first and the row second.

A single sheet which lists and analyzes data.

It consists of multiple worksheets represented by Tabs at the bottom of the Microsoft Excel’s screen. A workbook is the file that store data.

Color Code Sheet

1. Select the sheets you want to color.2. On the Format menu, point to Sheet, and then click Tab Color. You can also

right-click on the sheet tab and then click Tab Color. 3. Click on the color you want and click OK.

View Different Parts of Worksheets at the Same Time

Split panes

1. At the top of the vertical scroll bar or at the right end of the horizontal scroll bar, point to the split box.

2. When the pointer changes to a split pointer, drag the split box down or to the left to the position you want.


2


Freeze panes

Freezing panes allows you to select data that remains visible when scrolling in a sheet. For example, keeping row and column labels visible as you scroll.

1. To freeze a pane, do one of the following:

The top horizontal pane Select the row below where you want the split to appear.

The left vertical pane Select the column to the right of where you want the split to appear.

Both the upper and left panes Click the cell below and to the right of where you want the split to appear.

2. On the Window menu, click Freeze Panes.

View Different Worksheets at the Same Time

1. Open the workbooks you want to view.

To view multiple sheets in the active workbook, click New Window on the Window menu. Switch to the new window, and then click a sheet you want to view. Repeat for each sheet you want to view.

2. On the Window menu, click Arrange. 3. Under Arrange, click the option you want.

To view sheets in only the active workbook, select the Windows of active workbook check box.

Q3: What happen when you hide parts of a workbook? When it comes to printing does it print the hidden parts of a workbook? How do you prevent others from displaying hidden sheets, rows or columns? What can be hidden from applying the ‘hide’ command?

When you hide parts of a workbook, the data is removed from view but is not deleted from the workbook. If you save and close the workbook, the hidden data remains hidden the next time the workbook is opened. If you print the workbook, Microsoft Excel does not print the hidden parts. To prevent others from displaying hidden sheets, rows, or columns, you can protect the workbook or sheet with a password. You can hide workbooks and sheets to reduce the number of windows and sheets on the screen and to prevent unwanted changes. You can also hide selected rows and columns of data that you aren't using or that you don't


3


want others to see. You can hide most window elements in order to use as much of your screen as possible to display worksheet data.

Q4: How do you transfer the inserted content from one cell to another? How do you replicate a sequence such as the following? What are the other kinds of data sequences that can be created?

Monday Tuesday Wednesday Thursday Friday

Transfer Content

1. Firstly, double click the cell that needs to be edited. Then, select the characters in the cell which is going to be copied or moved.

2. To copy the character, select Edit from the menu bar, and then click Copy.

3. To move the character, select Edit from the menu bar, and then click Cut.

4. Lastly, click the cell where I want to paste the character. Select Edit and choose Paste and then press Enter key.

Sequence

1. Type the data example Monday into the selected cell. Select at least two cells from the starting values of trend.

2. Then drag the filled in the right or down direction. The values will increase or decrease depends on the sequence of the data.

3. Lastly, drag the fill handle to the right column.

The type of sequence that can be created using the fill handle are consecutive numbers, date, days, months, and years.

Q5: How do you merge scenarios from another worksheet? In what type of conditions can you do so?

It is easier to merge a scenario that is a named set of input values that you can substitute in a worksheet model when all what-if analysis that is a process of changing the values in cells to see how those changes affect the outcome of formulas on the worksheet. For example, varying the interest rate that is used in an amortization table to determine the amount of the payments. Models on the worksheets are identical. All changing cells on the source worksheet must refer to the corresponding changing cells on the active worksheet. Microsoft Excel copies all scenarios on the source sheet to the active worksheet.

1. Open all of the workbooks that contain the scenarios you want to merge. 2. Switch to the worksheet where you want to merge the scenarios. 3. On the Tools menu, click Scenarios.


4


4. Click Merge. 5. In the Book box, click a workbook name. 6. In the Sheet box, click the name of a worksheet that contains the scenarios you

want to merge, and then click OK. 7. Repeat this process if you want to merge scenarios from more worksheets.

Q6: How do you create headers and footers in Microsoft Excel? Can you insert a graphics in header and footer?

1. Firstly, select View from the menu bar. Then click at the Header and Footer.2. To create a custom Header or Footer on an existing built in Header and Footer,

click the Header or Footer in Header box or Footer box.3. There are Custom Header and Custom Footer.4. Click the Left Section, Center Section or Right Section box and click the buttons

to insert the header or footer into; for instance : insert number of pages, insert page number, insert date and time.

Yes, we can insert graphics in header and footer by following these steps:

1. On the View menu, click Header and Footer. 2. Click Custom Header or Custom Footer. 3. Click in the Left section, Center section, or Right section box. 4. On the row of buttons in the Header or Footer dialog box, click Insert Picture

and then find the graphic you want to insert. 5. Double-click the graphic to insert it in the header or footer section box. 6. If you want, do one or more of the following:

o To make changes to the graphic, click Format Picture on the row of buttons in the Header or Footer dialog box.

o To replace a graphic, select & [Picture], click Insert Picture, and then click Replace.

o To start a new line in one of the section boxes, press ENTER.

o To delete a graphic, select & [Picture] and then press DELETE.

Q7: Describe different types of reference styles used to refer cells and ranges of cells in MS Excel. Which reference style refers to columns with letters and rows with numbers? Which reference style can be used to analyze data in the same cell or range of cells on multiple worksheets within the workbook? Which reference style indicates the location of a cell with an ‘R’ followed by a row number and a ‘C’ followed by a column number?

Types of Reference Style

The A1 reference styleBy default, Excel uses the A1 reference style, which refers to columns with letters and refers to rows with numbers. These letters and numbers are called row and column


5


headings. To refer to a cell, enter the column letter followed by the row number. For example, B2 refers to the cell at the intersection of column B and row 2.

To refer to UseThe cell in column A and row 10 A10The range of cells in column A and rows 10 through 20 A10:A20The range of cells in row 15 and columns B through E B15:E15All cells in row 5 5:5All cells in rows 5 through 10 5:10All cells in column H H:HAll cells in columns H through J H:JThe range of cells in columns A through E and rows 10 through 20 A10:E20

Relative references A relative cell reference in a formula, such as A1, is based on the relative position of the cell that contains the formula and the cell the reference refers to. If the position of the cell that contains the formula changes, the reference is changed. If you copy the formula across rows or down columns, the reference automatically adjusts. By default, new formulas use relative references. For example, if you copy a relative reference in cell B2 to cell B3, it automatically adjusts from =A1 to =A2.

Absolute references An absolute cell reference in a formula, such as $A$1, always refer to a cell in a specific location. If the position of the cell that contains the formula changes, the absolute reference remains the same. If you copy the formula across rows or down columns, the absolute reference does not adjust. By default, new formulas use relative references, and you need to switch them to absolute references. For example, if you copy a absolute reference in cell B2 to cell B3, it stays the same in both cells =$A$1.

Mixed references A mixed reference has either an absolute column and relative row, or absolute row and relative column. An absolute column reference takes the form $A1, $B1, and so on. An absolute row reference takes the form A$1, B$1, and so on. If the position of the cell that contains the formula changes, the relative reference is changed, and the absolute reference does not change. If you copy the formula across rows or down columns, the relative reference automatically adjusts, and the absolute reference does not adjust. For example, if you copy a mixed reference from cell A2 to B3, it adjusts from =A$1 to =B$1.

3-D reference If you want to analyze data in the same cell or range of cells on multiple worksheets within the workbook, use a 3-D reference. A 3-D reference includes the cell or range reference, preceded by a range of worksheet names. Excel uses any worksheets stored between the starting and ending names of the reference. For example, =SUM(Sheet2:Sheet13!B5) adds all the values contained in cell B5 on all the worksheets between and including Sheet 2 and Sheet 13.

R1C1 reference You can also use a reference style where both the rows and the columns on the worksheet are numbered. The R1C1 reference style is useful for


6


computing row and column positions in macros (macro: An action or a set of actions you can use to automate tasks. Macros are recorded in the Visual Basic for Applications programming language.). In the R1C1 style, Excel indicates the location of a cell with an "R" followed by a row number and a "C" followed by a column number.

Q8: Define operator symbols. List down the symbols used and its functions.

Operators specify the type of calculation that you want to perform on the elements of a formula.

Microsoft Excel includes four different types of calculation operators: arithmetic, comparison, text, and reference.

Arithmetic operators To perform basic mathematical operations such as addition, subtraction, or multiplication; combine numbers; and produce numeric results, use the following arithmetic operators.

Arithmetic operator Meaning (Example) + (plus sign) Addition (3+3) – (minus sign) Subtraction (3–1)

Negation (–1) * (asterisk) Multiplication (3*3) / (forward slash) Division (3/3) % (percent sign) Percent (20%) ^ (caret) Exponentiation (3^2) Comparison operators You can compare two values with the following operators. When two values are compared by using these operators, the result is a logical value either TRUE or FALSE.

Comparison operator Meaning (Example) = (equal sign) Equal to (A1=B1) > (greater than sign) Greater than (A1>B1) < (less than sign) Less than (A1<B1) >= (greater than or equal to sign) Greater than or equal to (A1>=B1) <= (less than or equal to sign) Less than or equal to (A1<=B1) <> (not equal to sign) Not equal to (A1<>B1)

Text concatenation operator Use the ampersand (&) to join, or concatenate, one or more text trings to produce a single piece of text.

Text operator Meaning (Example) & (ampersand) Connects, or concatenates, two values to produce one continuous

text value ("North"&"wind")


7


Reference operators Combine ranges of cells for calculations with the following operators.

Reference operator Meaning (Example) : (colon) Range operator, which produces one reference to all the

cells between two references, including the two references (B5:B15)

, (comma) Union operator, which combines multiple references into one reference (SUM(B5:B15,D5:D15))

(space) Intersection operator, which produces on reference to cells common to the two references (B7:D7 C6:C8)

Q9: What is the difference between the formula bar and the name box? What happen when you move a formula? Would the cell reference change when you copy a formula? What happen to the name box when you select a range of cells?

Formula bar is the column which is at the top of Microsoft Excel Window that we use to edit values or formula in the cells. It displays the formula stored in the active cell. Formula bar is allowed to use values return by some function, like function with empty parenthesis can accept any number or argument which separated by commas (,) or semicolon (;). Argument can be numbers, formulas, or bookmark names.

Name box is a box to the left of the Edit Formula and Formula boxes. A range of cells can be given a name by simply typing the name in the name box after selecting the range of cells.

When you move a formula, the cell references within the formula do not change.

When you copy a formula, the cell references may change based on the type of reference used.

Q10: What is the difference between deleting a column and erasing the content of a column? Explain what would happen in both conditions?

Erasing the contents of a column : -Select the range to be erased and then press the DELETE key. Therefore, the contents of the cells will be erased but the cell is still there.

Deleting the column :-Select the column later, for example C.-Then, select Insert from the menu bar. Click at Columns.-Right click at the chosen columns, and select Delete.-The column will be deleted and other columns will fill in the place.


8


Q11: What is the function of ‘freeze panes’? What happen when you freeze an external data range?

Freezing panes allows you to select data that remains visible when scrolling in a sheet. For example, keeping row and column labels visible as you scroll.

1. To freeze a pane, do one of the following:

The top horizontal pane Select the row below where you want the split to appear.

The left vertical pane Select the column to the right of where you want the split to appear.

Both the upper and left panes Click the cell below and to the right of where you want the split to appear.

2. On the Window menu, click Freeze Panes.

Freezing an external data range retains the data but not its underlying query, so a frozen external data range cannot be refreshed.

1. Click a cell in the external data range that you want to freeze, and then click Data Range Properties on the External Data toolbar.

2. Under Query definition, clear the Save query definition check box.

Q12: By using Excel Help facilities, provide the following information:

(a) maximum number of significant digits(b) largest allowed negative number(c) smallest allowed positive number(d) maximum length of formula contents

(a) The maximum number of significant digits is 15.(b) The largest allowed negative number is -1E-307(c) The smallest allowed positive number is 2.229E-308(d) The maximum length of formula contents is 1,024 characters

Q13: Define trendline. How do you add a trendline to a chart? Is it possible to obtain the R-squared value and the equation through this command?


9


A graphic representation of trends in data series, such as a line sloping upward to represent increased sales over a period of months. Trendlines are used for the study of problems of prediction, also called regression analysis.

Add a trendline to a chart

1. Click the data series to which you want to add a trendline or moving average. 2. On the Chart menu, click Add Trendline. 3. On the Type tab, click the type of regression trendline or moving average you

want. o If you select Polynomial, enter in the Order box the highest power for the

independent variable.

o If you select Moving Average, enter in the Period box the number of periods to be used to calculate the moving average

R-squared value

1. Click the trendline for which you want to display the R-squared value. 2. On the Format menu, click Selected Trendline. 3. On the Options tab, select Display R-squared value on chart. 4. You cannot display an R-squared value for a moving average.

Yes, you can obtain the equation through this command for example linear, power, polynomial, logarithmic, exponential.

Q14: How do you protect a workbook? How do you protect worksheet elements? When we protect a structure within a workbook, what kinds of limitations are imposed upon fellow users?

Protect Workbook

Protecting workbook elements You can prevent users from adding or deleting worksheets, or displaying hidden worksheets. You can also prevent users from changing the sizes or positions of the windows you set up to display a workbook. These protections apply to the entire workbook.

To hide an entire workbook so that users can't see it but can gain access to contents such as macros, use the Hide command on the Window menu, and then save the hidden workbook.

Protecting a shared workbook You can protect a shared workbook so that users cannot return it to exclusive use or delete the change history log. If you want to require a password to remove this type of protection, you must apply the protection before you share the workbook. Applying the protection automatically turns on sharing. Unprotect these features turns off sharing and deletes all of the saved change history.


10


Alternatively, you can protect the sharing and change history without a password. You can apply this protection when a workbook is already shared, and then unprotect won't turn off sharing or delete the change history.

Protecting a workbook file from viewing and editing You can help restrict who can open and use the data in a workbook file by requiring a password to view or save changes to the file. You can set two separate passwords, one that users must enter to open and view the file, and another that users must enter before they can edit and save changes to the file. These passwords apply to the workbook file and are separate from the protection provided by the Protect Workbook dialog box.

Protect Worksheet Elements

Protecting elements from all users You can prevent users from inserting, deleting, and formatting rows and columns, from changing the contents of locked cells, and from moving the cursor to cells that are locked or to cells that are unlocked.

By default all cells on a worksheet are locked. Before you protect a worksheet, you can unlock cells where you want users to enter and change data, in two ways. To unlock cells for all users, you can use the Protection tab of the Format Cells dialog box. To unlock cells for specific users, you can use the Allow Users to Edit Ranges dialog box. Any ranges that you specify in this dialog box and don't assign a password for are also unlocked for all users. The cells you leave locked become protected only after you protect the worksheet.

Other worksheet features and elements for which you can restrict access for all users include hyperlinks, sorting, AutoFiltering, PivotTable reports, graphic objects, and scenarios. These protections apply to all users and the entire worksheet, not to individual users or data ranges.

For chart sheets, you can protect the contents of the chart from changes, and you can protect any graphic objects on the sheet, such as text boxes, from being changed or deleted. A protected chart sheet continues to be updated whenever the source data for the chart changes.

Giving specific users access to protected ranges If you have the Windows 2000 operating system, you can allow specific users to edit specific cells or ranges. Users to whom you grant access can edit the cells even if the cells are locked. Your access restrictions take effect only after you protect the worksheet.

The users you specify in the Permissions for range dialog box can automatically edit the range without entering the password. Other users are prompted for the password, and users who enter the password can then edit the range. If a cell belongs to more than one range, users who are authorized to edit any of the ranges can then edit the cell. If a user attempts to edit multiple cells at once and is


11


authorized to edit some but not all of those cells, the user will be prompted to select and edit the cells one by one.

Q15: Create a list of x and y values of different variables. Make a table with data points along with their error values, and draw a graph with errors bars shown (BEWARE OF LABELING).

Q17: The angle for a function should be in radians. So from the following angles, use EXCEL to obtain the Tangent function. (Hint: Use fill handle to avoid re-entering of the same formula).

(a) 180°(b) 45°(c) 75°(d) 36°(e) 236°


Q18: Multiplot: Write down any one formula with three constants (a, b and c) and one variable (x).(eg. y=a sin(bx) + c or y=a x + b log (x) - c …etc). You can also make up your own formula. Use Excel to calculate your chosen formula for a range of x values at five different sets of constant values and tabulate them as x vs y with x in the first column and y in the next four columns as follows:

No. xy values calculated using different set of constants

a= …. b=… a= …. b=… a= …. b=… a= …. b=…

Then, plot all the four curves in the same plot and label them differently. Comment on the effect of the constants on these plots.


Q19: By using any of your selected formula, perform calculations by entering the constants and variables separately. For example, force =…..units, density = ….
