So many things to learn from this video, such a nice explanation of concepts. Looking forward for more such videos. Thank you Eshan and team 👍

Since the hypothesis states that PYMK feature reduces engagement for people with more friends, would this experiment be designed only to run for that segment? Also, how do we define people with 'more friends'. Is there a threshold?

Good video, but he doesn't clearly explain why the lead analyst thinks that the lower engagement is due to the PYMN feature. Understanding that will help determine the right metrics for the A/B test.

That's a great point! It's important to understand the rationale before any plans or decisions!
