Product team wants to understand whether posts from friends drive more ‘social’ interaction than those from unconnected viewers and what other value unconnected audiences add.

How would you validate, using the available data, that content from friends is more social than content from unconnected viewers? Outline metrics, hypotheses, and statistical tests. Detail the concrete steps you would take to measure engagement for connected versus unconnected audiences. If engagement from unconnected viewers is lower, what alternative value could they provide and how would you quantify it?

Define socialness (e.g., reactions per view, reshare rate), run A/B-style comparisons, control for confounders; consider reach, content discovery, network growth as alternative value.
