TRANSCRIPT

Hello world, and thanks for joining me. My name is Mohit Deshpande, and in this course, we're gonna learn all about hypothesis testing. We're gonna be building our own framework for doing this hypothesis testing. That way, you'll be able to use it on your own data in your own samples, and you'll be able to validate your own hypotheses. So the big concepts that we're gonna be learning about in this course, we're gonna learn a little bit about probability distribution. We'll talk about random variables and what a probability distribution actually is. We'll talk about some very important distributions, like the Gaussian distribution and the normal distribution, that kind of serve as the backbone for z-tests and eventually t-tests. And then we're gonna get on to the actual hypothesis testing section of this, which is gonna include z-tests and t-tests and they're really ways that we can have a claim and then back it up with statistical evidence. And so we're gonna learn about how we can do that as well as the different conditions where we might wanna use one or the other, and all of our hypothesis testing examples are gonna be chock full of different examples so that you get practice with running hypothesis tests, and in our frameworks, we're also gonna use code, and so you will get used to using code to validate hypotheses as well. So we're gonna take the math that we learned in this, which is not gonna be that much, and then we're gonna apply it to, and we're gonna implement that in code as well, and then we're gonna use all this to build our framework and then answer some real-world questions and validate real-world hypotheses. We've been making courses since 2012, and we're super excited to have you on board. Online courses are a great way to learn new skills, and I take a lot of online courses myself. Zenva courses consist mainly of video lessons that you can watch and rewatch as many times as you want. We also have downloadable source code and project files that contain everything that we build in the lessons. It's highly recommended that you code along. In my experience, it's the best way to learn something, is to get your hands dirty. And lastly, we see the students who get the most out of these online courses are the same students that make a weekly plan and stick with it, depending, of course, on your own availability and learning style. So Zenva, over the past six years, has taught all kinds of different topics on programming and game development to over 300,000 students. This is across a hundred courses. These skills that they learn in these courses, by the way, are completely transferrable to other domains. In f ... https://www.youtube.com/watch?v=74K9OhN-KYA
