Welcome back! This is the fourth class in our Level Up series on statistics with Python. If you’re just tuning in, you can catch up on what we’re doing and review the first lesson here.
In this lesson we’ll learn about the Central Limit Theorem (CLT) by simulating it in Python.
The CLT is the basis for a few common statistical hypothesis tests, like Z-tests and t-tests. While many introductory statistics classes teach the CLT, very few actually attempt to prove it because that requires some complex math. In this session, we’ll bypass all that math by using Python loops to simulate the CLT. This helps build intuition for how hypothesis testing works, while also practicing our Python programming skills and avoiding math-y equations!
This is a fun stream because it is our first step into the world of inferential statistics. We’re no longer interested in simply looking at a sample of data by itself — we’re now starting to think about how to use a sample to gain an understanding of a population we cannot observe.
Here are some StackOverflow questions related to the work we did in today’s session:
Every Tuesday from now until March 2nd, we’ll be streaming a new session at 4PM EST. You can set a reminder for the stream for March 2nd here.
Finally, if you want even more stats content, you can sign up for the Master Statistics with Python interactive course this series was based on. This course was developed by Sophie and has many more quizzes, projects, and helpful nuggets that we can’t fit into our streams!Tags: codecademy, level up, python, statistics
