If you missed that video you can find it here: https://www.youtube.com/watch?v=DLjPPNhU1aI A book I highly recommend, especially for the non-mathematical reader, is "How Not to be Wrong" by Jordan Ellenberg. Find it here: https://www.amazon.com/gp/product/0143127535?ie=UTF8&camp=1789&creative=9325&creativeASIN=0143127535 However, not everyone going into data science necessarily has a statistics background. It begs an obvious follow-up question: how much statistics do you REALLY need for data science? Education is valuable but not every single thing you learn in a traditional statistics degree is a hard and fast requirement. Here are, from my perspective, the core skills you need: Fundamentals - Probability calculations including conditional probability/Bayes rule and the Central Limit Theorem - Basic understanding of distributions including properties of random variables such as expected value and variance - Full confidence interval framework - Full hypothesis testing framework including p-values, conclusions, Type I and Type II error Tools - Linear models (how to setup, interpret, iterate) - Machine learning models including setting them up in a programming language from pre-processing to outputting results, also understanding the bias-variance tradeoff and how to address over (and under) fitting - Survival analysis Reasoning - Assumptions of tests and models used - How bias affects results - Confounding variables and Simpson's Paradox PayPal: [email protected] Patreon: https://www.patreon.com/richardondata BTC: 3LM5d1vibhp1F7pcxAFX8Ys1DM6XLUoNVL ETH: 0x3CfC599C4c1040963B644780a0E62d45999bE9D8 LTC: MH8yPjvSmKvpmRRmufofjRB9hnRAFHfx32
Preparing download options
http://unidownloader.com/ website is the best way to download a video or a separate audio track if you want to do without installing programs and extensions.

The best quality formats are FullHD (1080p), 2K (1440p), 4K (2160p) and 8K (4320p). The higher the resolution of your screen, the higher the video quality should be. However, there are other factors to consider: download speed, amount of free space, and device performance during playback.
The browser/computer should not freeze completely! If this happens, please report it with a link to the video. Sometimes videos cannot be downloaded directly in a suitable format, so we have added the ability to convert the file to the desired format. In some cases, this process may actively use computer resources.
You can download a video to your smartphone using the website or the PWA application UDL Lite. It is also possible to send a download link via QR code using the UDL Helper extension.
The most convenient way is to use the UDL Client program, which supports converting video to MP3 format. In some cases, MP3 can also be downloaded through the UDL Helper extension.
This feature is available in the UDL Helper extension. Make sure that "Show the video snapshot button" is checked in the settings. A camera icon should appear in the lower right corner of the player to the left of the "Settings" icon. When you click on it, the current frame from the video will be saved to your computer in JPEG format.
It costs nothing. Our services are absolutely free for all users. There are no PRO subscriptions, no restrictions on the number or maximum length of downloaded videos.
