TED

Its videos run from 7 to 87 on a 0–100 scale, with a median of 58. That is a spread of 80 points — wide enough that a single level label would be false for the channel's own hardest videos. 74 of its 80 scored videos pass 40. 89% carry human-written subtitles rather than auto-generated ones.

vocabulary range

Read the vocabulary range as the channel’s own spread: in three of every four of its videos the vocabulary demand starts at the lower level or above, and stays at the upper one or below. The upper bound is how far the rare words reach, not how hard the speech is — a channel built on one specialised subject carries a high ceiling on perfectly ordinary sentences. For whether you can keep up, read the median difficulty next to it: that one is mostly about how fast people talk.

Each bar counts this channel’s videos in one ten-point slice of the scale. A median alone hides that shape, which is why the ranking shows a range rather than a single level. Bars from 40 up are dimmed because the advanced shelf begins at 43 — that is the part of the channel that stops being an easy watch.
