Intermediate Excel Questions for Data Analysts

Effective communication about the data is crucial in the role of a data analyst. While articulating data insights is a key skill, explaining all the tools, as well as the software that is used in the analytics of the data, is equally important, even if only some possess a natural talent for it. More often, being prepared for a range of questions during an interview demonstrates versatility and can also enhance our candidacy as well.

As the interview progresses, the level of difficulty in questions may increase, especially regarding our familiarity with the software. In the realm of data analytics, Microsoft Excel is termed to be the common as well as the basic tool, and with this, we might encounter inquiries about the functions and the tasks, like crafting SQL queries within the Excel sheet. For instance, we may be asked to elaborate on how we can easily perform data analysis by just making use of the Excel software. In response, we can effectively make use of various functions such as VLOOKUP or SUMIFS for the effective manipulation of the data. If asked about SQL queries in Microsoft Excel, we can convey that we leverage the power of SQL within Excel by just making use of the Po0wer Query Editor, which more specifically allows us to import, transform, and load data seamlessly, Hence showcasing our ability to explain not only about the data insights but also the tools as well as the software which are used in the analytics of the data is essential. It sets us apart from others and demonstrates our comprehensive skills in a way that resonates with the interviewers.


26. Define Excel chart in Excel, and how many types of charts are there?

A chart in Microsoft Excel is basically a feature that helps us to display the data through a range of visually intuitive graphs. These charts and the graphs can make it easier and quicker to comprehend data in comparison to just looking at the numbers on the selected worksheet. Some of the available charts on the Microsoft Excel mainly include the following ones:

  • Line graphs.
  • Bar graphs.
  • Pie charts.
  • Area graph.
  • Scatter graphs.
  • Surface graphs.
  • Doughnut graphs.

  • For example, Let us imagine that, when we are frequently formatting out the cells, then we need to insert specific formulas or create charts as well. Instead of manually repeating all these steps one by one, a macro can be easily created for the purpose of executing all these tasks instantly, as this enhances efficiency and also reduces the chance of errors in the manipulation of the data.

Moreover, in practical terms, we might record a macro for the purpose of automating the process of sorting as well as filtering out the data in an effective manner. And with a single click, the respective macro can sort information alphabetically. We can also apply filters that are based on specific criteria and even format the cells for better readability. By just encapsulating all these actions in a macro, Microsoft Excel users can save time and ensure consistency in the effective management of the data, thus making spreadsheet tasks more accessible to individuals with varying levels of expertise.

29. What is meant by the term relative cell address in Microsoft Excel?

In Microsoft Excel, the respective relative cell addressing is primarily a system that can be used for the purpose of indicating the locations of the selected cells within the formulas that adapt dynamically to the formula's position. It functions akin to giving navigational instructions from a starting point. When employing relative references, instructions are provided relative to the formula's current location as well. For instance, if in case the instruction is to move two cells to the right, this is contextually interpreted based on where the formula is copied or dragged out. The beauty of the relative cell addressing lies in its adaptability; when we replicate the formula in the other cell, then the instructions will adjust automatically, thus ensuring the formula always refers to a position relative to its new location. This dynamic quality streamlines our spreadsheet calculations, particularly while applying the same formula across the different sections of our spreadsheet, eliminating the need for manual adjustments effectively.


30. What is meant by the term dropdown list in Microsoft Excel?

A dropdown list in Microsoft Excel is basically considered a convenient tool that can be used for the entry and validation of the data, and more often, it lets us create a menu of the options within a cell, thus enabling a user to select a choice from a predefined list.

To implement this feature, we can make use of the "Data Validation function ."Clicking a small arrow next to the cell reveals a dropdown menu containing the specified options as well this helps us to maintain the integrity of the data by just restricting entries to the predefined list and reducing the errors, also ensuring consistency in the data. Dropdown lists are commonly used in various scenarios, such as selecting the names of the employees names or the project statuses.

Syntax:

It is used for the purpose of finding a value in the first column of a table, after that it will be returning a value in the same row from a specified column.

2. HLOOKUP:

Syntax:

HLookup is a value in the first row of the table, and used to returns a value in the same column from a choosen row respectively.

The lookup_value is what we are actually searching for, table_array is where we are searching, col_index_num or row_index_num is the column or row number in the table where the matching value is found, and [range_lookup] usually determines whether to find an exact match or an approximate match respectively. More often, these functions are useful for retrieving data from large datasets based on the specified criteria.


32. How one can make use of the Name Box function?

The "name box" function mainly refers to the special feature available in the spreadsheet software just like the Microsoft Excel or Google Sheets. More often, it allows us to assign a name to the specific cell or the range of the cells, and thus making it easier to reference and make use of those in formulas.

In order to make use of the name box function, we are required to follow the below-mentioned steps:

  1. Firstly, we will be clicking on the cell or we need to highlight the range of the cells where we actually want to have the name.
  2. After that, in the name box, that is located next to the formula bar, we are required to type the desired name for the selected cell or the range, and then after that we will be pressing the "Enter" button from our keyboard.
  3. We can now refer to this named range in the formulas instead of just making use of the cell references.
  4. In Microsoft Excel, we can also now manage named ranges by just moving down to the "Formulas" tab and then selecting out the "Name Manager." Here, we can easily edit, delete, or create new named ranges.

33. Is it possible to make use of the multiple data formats in the Pivot Tables?

Yes, the particular selected data can be easily imported from the different sources by just selecting out the "Data tab" and after that clicking on the Get External Data > From Other Sources as well. And with this many data formats can be easily exported some of them like: a text files, a worksheet, feeds realted to the data. Despite of all this, we still need to generate relationships that mainly exist between the imported tables and those which are in our worksheet before using them to create a pivot table.


34. How can one easily create a hyperlink in Microsoft Excel?

Now, for the purpose of creating a link in Microsoft Excel, we need to select the element that we wish to use as the anchor (this can be a cell or an object like a picture). We can then make use of a variety of pathways: selecting a Link from the Insert tab, right-click, and then we must need to select Link on the menu, or pressing the shortcut button that is Ctrl+K from our respective keyboard.
