I think people in our beautiful data field tend to forget that it's not about the most-complex and detailed algorithm, it's about the most functional one. On another note: IQR, you son of a gun that's exactly what I needed for my project - thanks for the reminder. Ha!

Great video Luke. I just want to say that your channel has helped through grad school. Everytime I was so stressed about school projects, your videos made me laugh and gave me motivation to keep working towards my degree. Just graduated this spring and will start my first job soon in the data analyst field. Thanks for reading this comment.

[@petenguyen1131]

Thanks Luke and Thu Vu. Wish you guys all the best. I used to be a Marketer, and since last year I've moved further to a new job as a Data analyst. I've been working on almost 15 projects. You know, at my very first project I was so nervous because the team they are nerds for real. Sometimes in the meeting, I feel like they speak another language 🤣. But the interesting point is that when you are on-job-learning, especially something related to math, you can learn then apply and practice them in real cases. The more you apply to your job the more it grows on you. I approve those math tools works really well in most case.

[@LukeBarousse]

Thanks for sharing this perspective, Pete!! I've felt the same way in some of the teams I've been on!

[@JoshBabin]

Another sweet video my dude. One thought: on the distribution plot, it marks 50% at the peak of the curve. While this is true on a normal distribution (where mean=median=mode), your specific distribution was skewed to the right. So the 50th percentile would have been to the right of the mode (peak of curve). Unless I'm wrong, then you should thoroughly pwn me lol

[@LukeBarousse]

Nope I think you are completely right. I had to make that animation in my video software. So it was done by hand (and not to scale). Thanks for pointing this out! 🙌🏼🙌🏼

The most advanced math I've used with data is the Naive Bayes Algorithm, or maybe statistical significance testing. Gathering the data is usually more involved than the analysis.

[@EricVulgaris]

Knowing the various data distributions is essential to the job as arithmetic if you're looking to be more than be a chart farmer. It's important for troubleshooting your dataset and provide that analysis that stakeholders really want. Cuz your bosses don't want just a chart. They want the answer to the question the chart supports. The story (or context for decisions) requires a firm understanding of data sampling, biases, and distributions and how that relates to the business. This part of stats is IMHO so much more vital than knowing probabilities. Like if youre a new hire, prepare to be shocked the number of times bosses make decisions around an "average" from a data set when the distribution isn't gaussian (e.g. ARPU is good for budgetary forecasting but not for detailed sales measurements)

[@LukeBarousse]

Can you do a video of the steps you take to learn about a database and tables when you encounter a new one that you have to work with for the very first time? What's the quickest way to get productive when dealing with a new database and understanding the relationships, etc...?

[@LukeBarousse]

Let me see what I can do on this topic. Thanks for suggesting this! 🙌🏼

[@dard4642]

There is a lot of integral calculus hidden within statistical distributions. The area under a normal distribution (the integral of that curve) is equal to 1 and a z-score of 1.96 (Z = 1.96) corresponds to the alternative hypothesis being in the first 0.95 of the integral, where 1.96 in the upper limit of integration on the interval of x under the curve. Z=1.68 is the upper limit of integration for 0.9 of the integral, etc. I get that this is formal calculus and probably isn't used by too many data analysts but I find that learning integral calculus first really helps people have a better intuition and understanding of statistical distributions. (Edit: formatting)

[@LukeBarousse]

Yeah I can agree with this. It def can help provide a deeper understanding of statistical distributions!
