The Only Data Science Explanation You Need

This video is for anyone who wants a no-nonsense explanation of what data science is and the type of work that data scientists do. Maybe you heard of data science and you wanted to learn more. Maybe you work with a data scientist and want to better understand their role, or you even have the goal of becoming one. This video was made for you.

Data science is actually quite a bit older than many of us realize. It was first mentioned with computer science and then with statistics.

Data science is an aptly named field. Data science is a domain where we work with data to generate some form of value. And we use scientific techniques to extract this value.

Thanks for watching everyone! Let me know below if you would be interested in a similar video to this for Deep Learning or Model Evaluation! 👇

I've never seen a video so effectively inform an audience of everything a complete outsider to the topic would need to know without BS and droning on. You made my career path easier and I aspire to be as fluid and effective as you are as a speaker. Thank you!

I agree, this is the only explanatory video about data science that one needs, and yet simple and concise :)

I noticed in this video you mention the tools used for a Data Scientist but don't say too much about the math that's used regularly. This seems to be a common trend on "How to Become a Data Scientist" videos. They almost exclusively talk about learning Python, R, SQL etc. but rarely go into any detail on the math involved in the field. I'm in a masters program for Data Science and it's pretty heavily math focused to begin. Just an idea for a future video.

Anyway, thanks for consistently putting content out, you're videos have really helped me in understanding the direction I want to go!

Great video, Ken!
One of the first examples of Data Science(though it was not called Data Science then) comes from John Snow’s famous map of the 1854 Broad Street cholera outbreak. Before germ theory was known, it was thought that Cholera was simply in the environment and that it spread at random. John Snow conducted interviews, mapped data points and graphed the results, leading to a single water pump being identified as the culprit. This was founding moment in Epidemiology and Public Health.

Just sharing my learnings as well. Cheers :D

I have watched at least 5 to 6:00 training videos on the subject of ml and deep learning etc. And I will tell you that it has taken me four times as much effort to understand that s*** sorry to use a four letter words then to the value that I got out of it. Whereas your of comments and explanations and conceptual arm waving has given me so much so many answers that I wish I hadn't wasted so much time on the four or five of the training videos. I think you should be creating at least another 5 or 10 videos, similar videos and different topics or concepts of the whole machine learning and and and and and and related topics. I am so happy that I found you your presence and I'm so very grateful for the effort to putting in and I would be even more grateful to see more videos from you. Thank you so very much. Enjoy your day!

THE EXPLANATION WE HAVE BEEN WAITING FOR!! 🙌🏼
...also... I hope it's okay... but now I'm going to drop a video next week titled: "The Only DATA ANALYTICS Explanation You Need" 🤣jk

[AaronMOliver]

Love the explanation of what DS is currently. It feels to me like the most interesting work is where the limits of our understanding math and the limits of computing power meet, forcing innovations.

Great vid as always!

Hi Ken, in 4:15 of your video, you mentioned Geography. I have basic to intermediate experience in GIS (spatial) data and geostatistics and working on improving my data wrangling, programming and ML skills in order to land a role as a geospatial data analyst/scientist.
Thanks for this short and insightful video, I was watching your content since 2020 when started my journey in learning data analytics.

[candidlyvivian]

Great video as usual Ken, super well explained! happy new year 😊

[CatyPerri]

My god you are the only person in this internet who actually explained what data science is.

[KillaHcam]

great stuff! I am in the process of hopefully moving into the Data Science world for my career and your videos are huge helps in my research to learn and understand in order to make the correct decisions for myself and career. Keep them coming.

[thevalueadder]

Thanks for this straightforward and in-depth explanation! I'm a beginner in DS, and I'm looking forward to applying it in my practice as a biomedical scientist, especially with a focus on infectious diseases.

[saturdayboy]

Wow, this video is brilliant. My only problem is that the title looks like a clickbait when it actually delivers what it promises haha.
So much chatter around data science these days but very few voices really know the field and of those even fewer have the clarity and generosity to share it in approachable/useful videos like this. Congratulations for the quality of your work and a big thank you.

[vjt]

As always Ken, superbly done. Concise and brief without getting into too much jargon and getting to the pith of it.

[mariopaul]

Monday's are always much better with a Ken Jee video!

Perfect way to start the week and great video Ken!

[jakewhitworth]

Would LOVE to hear the application of deep learning in DS. Right now I only hear about deep learning when it comes to voice recognition / natural language processing type of things

[anubhavgoyal]

Informative as usual! Really nicely explained Ken. Now I will just send this video if someone asked me to explain about Data Science

[shrutijain]

This is an Amazing
Data science explained so well 💯
Really like the example used and how everything is simplified .
