Excel for Data Analysis:
5 Most Used Excel Functions by Data Analysts

🧵⬇️

1️⃣ VLOOKUP / XLOOKUP:

VLOOKUP is used to look up values in a table or range by row, making it useful for merging datasets or retrieving specific data.

XLOOKUP (newer and more versatile) allows searching both horizontally and vertically and supports approximate matches.

2️⃣ INDEX-MATCH:

The INDEX-MATCH combination is often preferred over VLOOKUP for more flexibility. INDEX retrieves a value from a specified cell range, while MATCH identifies its position. Together, they allow more complex lookups, especially when the lookup column isn’t the leftmost column.

3️⃣ SUMIF / SUMIFS:

SUMIF and SUMIFS allow summing values based on single or multiple conditions, making it easy to analyze specific segments of data, such as summing revenue by region or time period.

4️⃣ COUNTIF / COUNTIFS:

COUNTIF and COUNTIFS are similar to SUMIF but are used for counting cells that meet specific criteria. These functions are helpful for calculating frequencies, such as counting occurrences of a certain value in a dataset.

5️⃣ Pivot Tables:

Pivot Tables aren’t a function but are an essential Excel tool for data analysts. They enable quick summarization, aggregation, and exploration of large datasets, allowing analysts to generate insights without complex formulas.

Excel Interview Question & Anwers for Data Analytics Interview✅
[Part-1]

What is Excel and what are its primary uses?

Excel is a software program created by Microsoft that uses spreadsheets to organize numbers and data with formulas and functions. Its primary uses include creating spreadsheets, performing calculations, and making charts.

How do you open a new workbook in Excel?

To open a new workbook in Excel, you can either click on "File" in the menu, then select "New" and "Blank Workbook," or you can press "Ctrl + N" on your keyboard.

Explain the difference between a workbook and a worksheet.

A workbook is like a file that contains all your data and is made up of one or more worksheets. Worksheets are the individual pages within a workbook where you enter and manipulate data.

How do you navigate between different worksheets in Excel?

To move between different worksheets in Excel, you can click on the tabs at the bottom of the Excel window. Each tab represents a different worksheet.

I have curated top-notch Excel Resources 👇👇
https://t.iss.one/excel_data

Q1. What are sets and groups in Tableau?

Sets and groups are used group data based on some specific conditions. The main difference between these two is that a group can divide the dataset into multiple groups whereas a set can have only two options which is either in or out. A user should choose to apply group or sets based on the requirements.

Q2. What is Power Pivot & Power Query?

Power Pivot is an add-on provided by Microsoft for Excel since 2010. Power Pivot was designed to extend the analytical capabilities and services of Microsoft Excel.

Power Query is a business intelligence tool designed by Microsoft for Excel. Power Query allows you to import data from various data sources and will enable you to clean, transform and reshape your data as per the requirements. Power Query allows you to write your query once and then run it with a simple refresh.


Q3. State some ways to improve the performance of Tableau?

Use an Extract to make workbooks run faster
Reduce the scope of data to decrease the volume of data
Reduce the number of marks on the view to avoid information overload
Try to use integers or Booleans in calculations as they are much faster than strings
Hide unused fields
Use Context filters
Reduce filter usage and use some alternative way to achieve the same result
Use indexing in tables and use the same fields for filtering
Remove unnecessary calculations and sheets.

Q4. What is macro in excel?

Macro refers to an algorithm or a set of actions that help automate a task in Excel by recording and playing back the steps taken to complete that task. Once the steps are stored, you create a Macro, and it can be edited and played back as many times as the user wants.

Macro is great for repetitive tasks and also eliminates errors. For example, suppose an account manager has to share reports regarding the company employees for non-payment of dues. In that case, it can be automated using a Macro and doing minor changes every month, as needed.

Most Excel users stop at formulas and PivotTables.

But that’s just the surface.

Would you like to stand out from the crowd?

You need to start thinking like an analyst.

Here are 4 data analysis techniques that will take your Excel skills to the next level:

Just to be clear, PivotTables are great for summarizing data…

But they're limited in helping you analyze it.

Here's why.

Data tables, including PivotTables, are good at two things:

Looking up exact values.
Comparing exact values.

Quite frankly, this is more reporting than analysis.

1) Visual Analysis > Data Tables

Tables summarize. Charts reveal.

Visuals like:

Histograms (for distributions)
Scatter plots (for relationships)
Line charts (for trends)

...make patterns jump out.

Good luck seeing these patterns in a monster PivotTable.

Instead, PivotTables feed your charts.

2) RFM Analysis:

This is a simple but powerful analysis technique to evaluate customers:

(R)ecency: How recently they purchased.
(F)requency: How often they purchase.
(M)onetary: How much they spend.

RFM analysis is super simple to implement in Excel.

AND

It's not just for customers.

At its core, RFM analysis is about analyzing data based on behaviors.

You can define the analysis however you would like.

Take healthcare as an example.

Analyzing patients:

(A)ge
(B)lood pressure
(W)eight
(E)xercise minutes per week

The possibilities are endless!

Like for remaining 2 ❤️

#excel

3) Cluster Analysis

Sometimes, patterns aren’t apparent until you group the data.

Two examples:

Segment users by behavior
Classify patients by characteristics

Start with a scatter plot of two columns.

Look for any clusters.

Then, figure out what defines each cluster.

Better yet...

Use Python in Excel for cluster analysis.

Python in Excel is included in Microsoft 365 subscriptions.

It's your gateway to battle-tested analytics like k-means clustering.

This will allow you to scale to using many columns to find hidden patterns.

It's the future of Excel.

4) Logistic Regression

This one’s for when you want to predict something like yes/no, true/false, approve/deny, etc.

It helps answer questions like:

Approve this application?
Will the customer churn?
Is this claim fraudulent?

You can implement logistic regression using Solver.

Better yet...

Use Python in Excel.

People have implemented logistic regression using Solver for years.

But here's the problem.

It's error-prone and doesn't scale.

Python in Excel eliminates these problems and gives you way more insights.

It's the future of Excel.
