📊 How to use Power BI DAX - Tutorial
Вставка
- Опубліковано 24 чер 2024
- In this step-by-step tutorial for beginners, learn how to use DAX (Data Analysis Expressions) in Microsoft Power BI. DAX is a formula language with functions. If you've ever written formulas in Excel, you'll find that DAX is very familiar.
We'll start by loading the sample data into a data model. Next, we establish relationships between the various tables.
Once the setup is complete, we'll write our first measure. A measure is a calculation that runs across our data model. You'll learn about a few different functions, including sum and count. You'll also learn how to comment your expressions.
Next, we create a measure using operators, like addition, subtraction, division, and multiplication. We then dive into how you can create measures using a graphical user interface called Quick Measures.
We then move onto creating a calculated column and talk about the advantages and disadvantages of columns vs. measures.
We then dig into iterator functions and when you would use them compared to an aggregator function. Iterator functions include sumx, countx, averagex, maxx, minx, and rankx.
Next, we look at the date functions that are available and we use the one called weekday.
We wrap up by looking at some logical functions, including find, if, and calculate.

I’ve watched several tutorials on Dax but yours stands out more and straight to the point. Thanks Kelvin
Today I went to a work interview (Thursday). They asked me if I was good on Power BI, and I never heard about it before. They said they could get around it, but I said I would be able to master it by Monday. Your videos popped up on my search and as I followed them, I feel like I'm ready in just one day. Really nice, powerful and simple at the same time program. Thanks to your tutorials, the introduction to this program was easy for me. Keep up with these videos. You will be the first search going on from here for software tutorials for me.
Kevin, you are such a great teacher. 🤩Thank you for keeping it very simple and clear. I love the way you explain everything and I am excited to watch more of your training videos for DAX. I have found Dax hard to learn but you make it fun and exciting. 😀
Do you know the different between power BI vs. Power Query?
Thank you very much, Kevin! I've just watched a few DAX intro videos from 5 different instructors, and your explanation is by far the best!
What a great teacher. You just made DAX look less of a mystery to me. never thought I will take on DAX and be this happy. Thank you Kevin. God bless you Sir
It's Amazingggggggggg! The way you've explained just makes me wanna learn more. We need more videos on DAX please!
Hey,
I'm EC engineer... Can I learn Power BI? Which language or software I should learn alongside power BI?
what is job opportunity for freshers in india?
Please guide.... 🙏🏻
@@dexxxxxxxx Hey sure. You can learn power BI. You don't need to learn any additional software, however it's recommended to learn Excel (if not learnt). You'll be good to go.
@@BlushStix thank you ma'am...
How much salary fresher can earn with power BI?
@@dexxxxxxxx A power BI developer can earn anything between 3.5lac to 10lac in India. You need to have knowledge about Fax when you'll learn power BI, make sure DAX is included in it.
@@BlushStix that's appealing salary... 🤯
Thank you very much for information 🙏🏻
Thanks very much for this! It's been a while since I last used Power BI DAX functions and needed a refresher. Your video turned out to be so much better than what I had initially expected! I hope you can do more tutorials on complicated DAX, they used to give me so much headaches!
I am absolute beginner in Power BI Dax formulas. But now by watching this video I understood how to use them and about their core functionalities. Thanks Kevin great effort.
Glad it was helpful!
It is usually tough to start gradually you will get a hand of it. Think about it, as if you are in excel. I tried to make a video on DAX for beginners.. kindly check it out...
Kevin, you are such a great teacher!
I've spent 3 months learning from some other guys on UA-cam and doesn't understand anything. But your 37-min video just changed anything, I could understand a bit more on how star scheme, DAX, new colume, measure,... works. That's just great!
This is fantastic, I had basic idea about power BI and DAX... but this video helped me to get into detail on calculation part... It was easy to understand and learn. Thanks a lot 🙂
Kevin, this instruction is awesome. I'm pretty new to Power Bi but I've been performing data analysis for a long time. Your instruction touched on many topics that quickly made sense to me (leveraging my previous experience with Excel) and the examples (following along with your example files) cleared up any questions I had. I only wish I had Power Bi 30 years ago (yes, I'm old). Thank you.
That means I must be old too. Perhaps better to say that you are experienced (or even highly experienced)! Cheers - Dave
Kevin, you are a great teacher. You explain very details and clear.
Thank you for sharing your knowledge.
Kevin, I just started a job at an accounting firm and we use Power BI as a tool during audits. This is amazing really. Great work explaining every step, it's extremely helpful!
Hi Carel! Please what are some of the use Cases in using Power BI for Audit....? Thanks ...
How do you use power bi for audits? I’m curious because I was actually wondering if there was applications for using power BI in the finance industry.
Hey Kevin! Now I finally understand the difference between aggregate functions and iterate functions. Two thumbs up to you.
This was awesome!! We need more advanced Power BI videos.
This video summarizes what took me 1 month to learn from DAX pdf book. Great work Kevin! Thanks for this!
Nice video. Very descriptive with good examples. I would have loved it if, when you were doing % and margins, you showed how big a % of total profits each customer was. So the customer profit % of total profit, and in the same table. That would have been a great real world addition 😊
Thanks a lot Kevin! I keep coming back here for the DAX measures using your cookie examples. Makes it so easy to understand. Power to you!
Each time I saw your tutorials...I end up watching your video by saying you a big thank you from the bottom of my heart...it is really helpful Kevin...you are truly great teacher...thanks once again.
Omg, you are the BEST teacher I have ever encountered. I don't think I ever thought I could be so grateful to someone I've never even personally met, thank you!
Kevin you are just amazing ! Thank you so much for profound and comprehensive tutorial. I'm grateful
Thank you Kevin!! You are a great teacher! I am new to Power BI. You have a very clear explanation and it's easy to follow. I hope to continue see your videos and learn from you. Thank you for sharing your knowledge!!
Thank you Kevin 👍🏻
I’m a final year student student studding Business IT. Data analyst and science are my career path I’m considering cause I’m efficient in excel, sql and a beginner in python language. Your power BI tutorial is a top notched for me. I got a job interview recently for a data analyst role. After having gone through your tutorials over the past few months, I stood out during the interview and the panelists were impressed. The only challenge I had was that I’m yet to complete my course but I believe after I’m done I will get one in that area.
👍🏻👍🏻👍🏻
Thank you so much Kevin! I have been struggling a bit with some of these concepts in DAX and this has made everything so much clearer for me. I can't wait to go back and rewrite some of my old measures and create new more powerful ones, especially with the Calculate Function.
Really useful, thank you!! I like that I can follow along with the sample files real time. Love the format!
You are a true teacher Kevin, Thanks for clear explanations
Your videos are the cleanest, neatest and smoothest videos anyone can ever come across. Hats off to your hard work!
Kevin. You're a legend! Thank you for this. Hands down best DAX tutorial. Going to watch again and follow through with the files you provided.
Thanks for the note BrotherCole 94! Much appreciated 👍
Hi Kevin, another great video as usual;) - however, like someone already pointed out on the comments below (Jonathan Porter), there's a mistake on the bar chart - Orders should add up to 700 but they are not. This is because the Values field should be summarised by Count. Cheers
Great video, I really enjoyed watching it. I'm on day 2 of my new Manager of People Analytics position, and this came in super handy. Thank you, Kevin.
Hey Kevin, great stuff! You have made it really easy to understand Power BI. I would love to see more videos on Power BI which cater to the advanced crowd.
Kevin, you really mastered every product of Microsoft...very nice session. Thanks

@@dexxxxxxxx Hi and thanks for your question. Power BI is a small part of a massive and very lucrative field, which is Data Warehousing and Business Intelligence. With the rise of big data, BI has become a high-demand career.
So, yes - there are lots of jobs available. You can choose to focus just on Power BI or focus on BI in general, Data Warehousing or Dimensional Modelling.
One of the Best DAX class in UA-cam. ! Very helpful .. Keep teaching !!

Thank you Kevin. you are such a great teacher :) i always thought DAX will be hard to learn.. but your explanation made me to understand easily. 😀
Explained in a short, simple, and impressive way ..... Great video
What a great tutorial. Very clear explanations. 10 out of 10.
For the bar chart of the weekdays at around 29:55, the values add up to over 700 (greater than the number of rows in the data). To correct this issue, in my version of Power BI, for the bar chart, I had to select "Count of Day of Week" in "Values" and then place "Day of Week" in "Axis". Thanks so much for your work Kevin! I appreciate your clear overview.
I spotted the same and left another comment;)
Day of week vs Count of Day of Week? That still wont mean anything. It should have been Day of Week vs Units Sold.
I think it should be count of order id
I am a beginner and I find this video very informative and explicit ❤
Great video. I really enjoy your style of explanation. I also greatly appreciate the sample files so I can follow along.
Excellent tutorials -- thanks Kevin! Wish you could do some more!
You're amazing. i was hoping to find more videos on your channel on Power BI. You do a good job at teaching.
One of the best videos on DAX. Thanks Kevin
Thank you so much for this, after taking so many courses still i wouldn't able to learn, but after watching this I'm pretty sure that little little things make you smarter,
