2. Short Answer Type Questions

Question 1.

What is Formatting?

Answer:

Formats are changes that are made to Excel worksheets in order to enhance their appearance and/or to focus attention on specific data in the worksheet. Formatting changes the appearance of data but does not change the actual data in the cell, which can be important if that data is used in calculations. For example, formatting numbers to display only two decimal places does not shorten or round values with more than two decimal places. To actually alter the numbers in this way, the data would need to be rounded using one of Excel’s rounding functions.

Question 2.

Define Number Format in Excel.

Answer:

By applying different number formats, you can change the appearance of a number without changing the number itself. A number format does not affect the actual cell value that Excel uses to perform calculations. The actual value is displayed in the formula bar. By applying different number formats, you can display numbers as percentages, dates, currency, and so on.

Question 3.

What are the standard operators used in simple formulas?

Answer:

Excel uses standard operators for formulas, such as a plus sign for addition (+), a minus sign for subtraction (-), an asterisk for multiplication (*), a forward slash for division (/), and a caret (Λ) for exponents.

All formulas in Excel must begin with an equals sign (=). This is because the cell contains, or is equal to, the formula and the value it calculates.

Question 4.

What is a cell reference?

Answer:

A cell reference refers to a cell or a range of cells on a worksheet and can be used in a formula so that Microsoft Office Excel can find the values or data that you want that formula to calculate.

In one or several formulas, you can use a cell reference to refer to :

- Data from one cell on the worksheet.
- Data is contained in different areas of a worksheet.
- Data in cells on other worksheets in the same workbook.

Question 5.

What are the parts of a Function?

Answer:

The order in which you insert a function is important. Each function has a specific order—called syntax — which must be followed in order for the function to work correctly. The basic syntax to create a formula with a function is to insert an equals sign (=), function name (SUM, for example, is the function name for addition), and argument. Arguments contain the information you want the formula to calculate, such as a range of cell references.

Question 6.

Define Sorting.

Answer:

Sorting is a common spreadsheet task that allows you to easily reorder your data. The most common type of sorting is alphabetical ordering, which you can do in ascending or descending order.

To sort in alphabetical order :

- Select a cell in the column you want to sort (In this example, we choose a cell in column A).
- Click the Sort & Filter command in the Editing group on the Home tab.
- Select Sort A fo Z. NOWT the information in the Category column is organized in alphabetical order.

You can sort in reverse alphabetical order by choosing Sort Z to A in the list.

Question 7.

Define Filter.

Answer:

The basic Excel filter (also known as the Excel Autofilter) allows you to view specific rows in an Excel spreadsheet while hiding the other rows in the worksheet. When a filter is added to the header row of a spreadsheet, a drop-down menu appears on each cell of the header row. This provides you with a number of filter options that can be used to specify which rows of the spreadsheet are to be displayed.

3. Long Answer Type Questions

Question 1.

What are Merge and Centre? Write down the steps to merge a group of cells.

Answer:

If you go to the Home menu in the ribbon and look in the Alignment grouping of commands, you will see a small icon in the lower, right-hand corner called Merge and Center. This command does just what it implies. It not only merges the cells into one larger cell, but it also centers the text. Merge and Center improves the appearance of a title or header by centering the text over a particular section of the spreadsheet. If you click on the More icon to the Merge and Center command, you will see other Merge options.

- The first one is Merge Across. This will merge multiple cells and more than one row at the same time. The text will remain left-justified.
- Then there are Merge Cells. This will merge multiple cells on one row and will keep the text left-justified.
- Finally, you have Unmerge Cells, which will undo the merged cells.

Let’s take a look at an example using the Merge and Center command. Imagine you are a painting contractor for residential homes. You created a spreadsheet to include several different costs for work requested by a new client. You have everything formatted nicely. The title, which includes the name of the client, the estimated number, and street address has been entered into cell Al. It would be nice if we could quickly and easily center the title across the top of the spreadsheet. Here are the steps.

- Highlight the cells you want to merge. (In our example, Al through FI),
- Go to the Home menu in the ribbon.
- Look in the Alignment grouping of commands.
- Click on Merge and Center.

Just like that, your title is centered and the cells have been merged into one larger cell. The benefit? Well, besides it looks better, you can make changes to the cells below and the title will remain centered: For instance, you can add a column (or delete one) and your title will not be affected. One important note about the Merge command: merging cells can delete data. Only the data in the upper-left cell will be kept once the cells have merged. Do not place data in every cell if you plan on merging multiple cells into one larger cell.

Question 2.

What is Conditional Formatting? Write down the steps to create a conditional formatting rule.

Answer:

Conditional formatting in Excel enables you to highlight cells with a certain color, depending on the cell’s value.

Highlight Cells Rules

To highlight cells that are greater than a value, execute the following steps.

1. Select the range A1:A10.

2. On the Home tab, click Conditional Formatting, Highlight Cells Rules, Greater Than…

3. Enter the value 80 and select a formatting style.

4. Click OK.

Result. Excel highlights the cells that are greater than 80.

5. Change the value of cell A1 to 81.

Result. Excel changes the format of cell A1 automatically.

Question 3.

What is a cell? How can we insert a new cell in our current worksheet?

Answer:

A cell is an intersection between a row and a column on a spreadsheet that starts with cell Al. Below is an illustrated example of a highlighted cell in Microsoft Excel; the cell address, cell name, or cell pointer “D8” (column D, row 8) is the selected cell and the location of what is being modified.

Insert Cells into an Excel Worksheet

Having to insert extra cells to an Excel worksheet from time to time is a common practice: data gets forgotten and must be added, space must be made for new data, or existing data gets moved about when the sheet is reorganized.

Whatever the reason, there is, as is the case with all Microsoft programs, more than one way to accomplish the task of inserting cells to an Excel worksheet.

Question 4.

What is a Formula? Write down the steps to create a simple Formula in Excel.

Answer:

A formula is an expression that calculates the value of a cell. Functions are predefined formulas and are already available in Excel. For example, cell A3 below contains a formula that adds the value of cell A2 to the value of cell A1.

Steps to create a simple formula in MS Excel

You can create a simple formula to add, subtract, multiply or divide values in your worksheet. Simple formulas always start with an equal sign (=), followed by constants that are numeric values and calculation operators such as plus (+), minus (-), an asterisk(*), or forward-slash (/) signs.

For example, when you enter the formula =5+2*3, Excel multiplies the last two numbers and adds the first number to the result. Following the standard order of mathematical operations, multiplication is performed before addition.

- On the worksheet, click the cell in which you want to enter the formula.
- Type the = (equal sign) followed by the constants and operators that you want to use in the calculation.

You can enter as many constants and operators in a formula as you need, up to 8192 characters.

Question 5.

What is a Function? Write down the steps to create a basic Function in Excel.

Answer:

In Excel, a function is a preset formula used for calculations. Like formulas, functions begin with the equal sign ( = ) followed by the function’s name and its arguments. The function name tells Excel what calculation to perform. The arguments are contained inside round brackets. For example, the most used function in Excel is the function, which is used to add together the data in selected cells.

The SUM function is written as –

= SUM (D1: D6 )

Here the function adds the contents of cell range D1 to D6 and displays the answer in cell D7.

The parts of a function :

The order in which you insert a function is important. Each function has a specific order called syntax—which must be followed in order for the function to work correctly. The basic syntax to create a formula with a function is to insert an equals sign (=), function name (SUM, for example, is the function name for addition), and argument. Arguments contain the information you want the formula to calculate, such as a range of cell references.

- Click on the Shift cells right option in the dialog box
- Click OK to add the two cells to the worksheet and to close the dialog box
- Cells A2 and B2 should now be blank and October should be located in cell C3
- Type February into cell A2 and June into cell B2.

Question 4.

Discuss the cell reference in Excel.

Answer:

For many spreadsheets, you won’t want to go back to the original formula to change all the information you’re working with. This is where cell references come in handy. By entering a reference to another cell on the worksheet, you can tell the formula to work its calculation with whatever number is placed in that cell. The formula can then be changed quickly by trying out different numbers in the reference cell.

To reference a cell, simply enter the location of the call as designated by its column and row; for example, A1 is the cell in the top left corner of the spreadsheet. To reference a cell on another worksheet within the same workbook, type the name of the worksheet followed by an exclamation point, then the location of the cell. So Sheet !A1 would refer to the A1 cell on the worksheet titled “Sheet.” If you want to reference a range of cells, use a colon between the first and last cell of the range. The formula =SUM(A1:A12) will calculate the total sum of all the figures in the range from A1 down to A12.

Question 5.

Demonstrate the use of AutoSum in Excel.

Answer:

Using AutoSum to select common functions
