2. Short Answer Type Questions

Question 1.
What is a Chart in MS Excel?
Answer:
Charts are used to display series of numeric data in a graphical format to make it easier to understand large quantities of data and the relationship between different series of data. To create a chart in Excel, you start by entering the numeric data for the chart on a worksheet. Then you can plot that data into a chart by selecting the chart type that you want to use on the Insert tab, in the Charts group.

Question 2.
Write down types of Charts in MS Excel.
Answer:
The list of charts in MS Excel

• Column charts
• Line charts
• Pie charts
• Bar charts
• Area charts
• XY (scatter) charts
• Stock charts
• Surface charts
• Doughnut charts
• Bubble charts
• Radar charts

Question 3.
What is a Pivot Table?
Answer:
Pivot tables are one of Excel’s most powerful features. A pivot table allows you to extract the significance from a large, detailed data set. An Excel pivot table can summarize the data in the above spreadsheet, to show the number entries or the sums of the values in any data column. For example, the pivot table on the right shows the total sum of all sales, for each of the four salespeople, for the first quarter of 2016.

Question 4.
What is Data Tools?
Answer:
In Microsoft Excel Data Tools are simply tools that make it easy to manipulate data. Some of them are used to save your time by extracting or joining data and others perform complex calculations on data.

Question 5.
Define What-if analysis?
Answer:
What-if analysis is the process of changing the values in cells to see how those changes will affect the outcome of formulas on the worksheet.
Three kinds of what-if analysis tools come with Excel: scenarios, data tables, and Goal Seek. Scenarios and data tables take sets of input values and determine possible results. A data table works only with one or two variables, but it can accept many- different values for those variables. A scenario can have multiple variables, but it can accommodate only up to 32 values. Goal Seek works differently from scenarios and data tables in that it takes a result and determines possible input values that produce that result.

Question 6.
What is Goal Seek?
Answer:
The goal seeks function, part of Excel’s what-if analysis toolset, allows the user to use the desired result of a formula to find the possible input value necessary to achieve that result. Other commands in the what-if analysis toolset are the scenario manager and the ability to create data tables. This guide will focus on the goal seek command.

Question 7.
What is Macro?
Answer:
It allows you to perform multiple operations just by clicking a simple button or changing a cell value or opening a workbook etc. It enables you to work in a smart and efficient way. In terms of productivity, it is very productive as it reduces lots of manual work and gets things done very fast.

3. Long Answer Type Questions

• If you want to create a second chart, click somewhere in the worksheet to “deselect” the current chart first, or the new chart will replace the current chart.

Question 2.
Write down the Elements of a Chart.
Answer:
Basic Elements of Excel Charts
The above chart is the basic charts in Excel, We can customize the charts by dealing with different Chart Element Objects and their properties. In this session we will focus on different elements of charts objects: Here is an examples Column Chart for the same data shown above :

And here I have marked the basic chart elements in Excel each element with different clor for understanding purpose. Most of the time we generally deal with Chart Area, Plot Area, Chart Title, Legends, X-Axis, Y-Axis, Data Labels Data Series, and Gridlines. Here is the pictorial representation of Chart Elements or Chart Objects in Excel:

Now will see each element of the Excel Chart in detail :

Chart Area
Chart area in Excel Charts is the largest element (portion) of the Chart. We can format the Chart Area and change its border and background colors to make the charts look more cleaner. Legends, Chart Titles, and Plot Areas are the three major child elements of Chart Area. Generally, we do not change the background color of the charts to make them look more professional. Charts look more cleaner with white or default background color. However, we can change the background color to suit the other parts of the excel sheets to make them consistent.

Basic Elements of Excel Charts – Plot Area
Plot Area is the second-largest element (portion) in Excel Charts. It covers the actual chart data area. We can access the Plot Area and Format it to suit our needs. It is the same as Chart Area, if your project needs different background color then we change it. Otherwise default background color (white) looks more cleaner.

Question 3.
What is Convert Text to Columns? Write down the steps to convert Text to columns.
Answer:
Sometimes we need to separate the contents of one Excel cell into separate columns. For this, you can use the ‘Convert Text to Columns Wizard’.

1. Open the worksheet that contains the text you would like to convert to columns.
2. Select the cells that you would like to convert.
3. On the Data tab, click Text to Columns in the Data Tools group.
4. Choose the format of your current data. Select Delimited if the text contains a character such as a comma, tab, space, or semi-colon to separate the various fields. Otherwise, select Fixed Width if there are a certain number of spaces between each field.
5. A preview of the data in columns appears below, according to the delimiter selected. Click Next.
6. You now need to choose the format for each of the columns. Select the column heading in the Data preview and then select a data type from the column data format options.
7. A preview of your selected data appears below. Click Next.
8. Select the type of character that separates the various fields. You can select as many as are applicable. If you would like to include your own characters that aren’t listed, select the Other checkbox and enter the specific character in the field provided.
9. Once you have selected the data type for each column, click Finish.
10. Your text will now appear in several columns, depending on the number of delimiters in the original list.

Question 4.
What is Data Validation? How to create a Data Validation Rule?
Answer:
Data validation allows you to control exactly what a user can enter into a cell. In our example, we can use data validation to ensure that the user chooses one of the three possible shipping options. To make things even easier, we can insert a drop-down list of the possible options. This kind of data validation allows you to build a powerful, fool-proof spreadsheet. Since users won’t have to type in data manually, the spreadsheet will be faster to use, and there’s a much lower chance that someone can introduce an error.

Data validation in Excel
Since we already have a list of shipping options in the Shipping worksheet, we’re going to tell Excel to use the data in that list to control which values a user can select. But before we do this, we actually need to name the cell range first. Naming cell ranges is one way to keep track of important cell ranges in your spreadsheet.
To create a data validation drop-down list:
Select the cell where you want the drop-down list to appear. In our example, that’s cell E6 on the Invoice worksheet.

1. On the Data tab, click the Data Validation command.
2. A dialog box will appear. In the Allow: field, select List.
3. In the Source: field, type the equals sign (=) and the name of your range, and then click OK. In our example, we’ll type =ShipRange.
4. A drop-down arrow will appear next to the selected cell. Click the arrow to select the desired option. In our example, we’ll select Standard. Alternatively, you can type the shipping option, but Excel will only accept it if it is spelled correctly.
5. The selected value will appear in the cell. Now that we’re searching for the exact name of a shipping option, our VLOOKUP function is working correctly again.

Question 5.
What is Protection? Write down the steps to protect a Worksheet.
Answer:
