The Only Data Science Explanation You Need

Күн бұрын

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.

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!

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 observation Grant! This video was more targeted for those who aren't planning on becoming data scientists, just to get a feel for what the field is. (Hopefully) in my videos more catered to people wanting to learn the profession I have more of the relevant math. I am definitely planning to make a few more videos on the math in the future. Thanks again for watching!!
