@research-focus-group, we’ll now be looking at Hypothesis Testing. Hypothesis tests are required to make systematically study your assumptions about the data and how you model it. While working as a QR, it is important to systematically list down your assumptions and hypotheses and ensure what that the features/parameters that you’re using for your models are corroborated by your data.
This is also an interviewer-favorite topic when you’re going for your QR interviews. Have fun learning!
