To learn about hypothesis testing and statistical significance, you’ll work hands-on with multiple datasets on weight loss data — are patients losing weight due to pure luck, or is it a diet pill? You’ll run the numbers and find out!
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser.
