Data transformation helps to clean, pivot, transpose, merge and prepare model-ready data.

For any data analysis project, we are following CRISP-DM (Cross-industry standard process for data mining) framework.

In this framework, data processing ( data transformation) is one of the key steps to start with the project.

In previous blogs of this series (Data Analysis in Power BI), we get an idea…

We are going to explore CONCATENATE, CONCATENATEX, COMBINEVALUES, EXACT, FIND, SEARCH, LEFT, RIGHT and MID Text functions in DAX using practical examples.

In any data analysis project, the text functions of DAX are playing very important roles. Using these functions we can fulfil some customer requirements which are related to the data visualization perspective.

In this blog, you are going to explore how you can use different DAX text functions like CONCATENATE…

Some more possible interview questions and answers about DAX in Power BI based on my experience and understanding.

I hope, now you got some idea about DAX related interview questions after going through my previous blogs on DAX interview questions.

If you have missed that, here are the links for your reference.

Interview Questions — DAX in Power BI — Part 1 | by Arpita Ghosh | Analytics…

Some more possible interview questions and answers about DAX in Power BI based on my experience and understanding.

In the previous blog, we have gone through some context and relationship-related questions and answers.

In this blog, we will go into aggregation related questions.

Please remember, only questions and answers can’t help you to clear any interview, you have to practice each and every syntax. …

You will learn how to Create a What-if Parameter in Power BI.

In any data analysis project, whenever we analyze data, always want to find out, some what-if scenarios. For example, what if sales increased by 10% or what if we decreased item cost by 1%.

These what-if analyses can be very helpful for any decision-making process.

Power BI has an AI-driven…

It’s a continuation of possible interview questions and answers about DAX in Power BI based on my experience and understanding.

In the previous blog, we learn 12 interview questions and answers on DAX.

Now in this blog, we will get into a deeper level of questions.

Please remember, only questions and answers can’t help you to clear any interview, you have to practice each and every syntax. …

A complete guided case study in Power BI based on the Kaggle data set.

Introduction

In this blog, we are going to explore COVID vaccine data and try to find out the inference of how the immunization process is going on worldwide.

Source of Data

For the case studies, Kaggle is a good source of data. So this time I consider below dataset

  1. It has two files, but…

You will learn how to build statistical visuals like decision trees in Power BI.

The decision tree is an equally important part when we are using the Decision Tree machine learning algorithm for our data science project. Power BI has some small visualization capability and custom visual features are enabling to implement this.

In this blog, we are going to explore one statistical visualization…

You will learn how to build smart visualizations like correlation plots in Power BI.

Correlation Plot and Decision Tree in Power BI

A correlation Plot is an important visualization for any data analysis or data science project. Power BI has some small visualization capability and custom visual features are enabling to implement this.

In this blog, we are going to explore the one smart and AI visualizations, named correlation plot.
