Videos categorized as News & Politics scored significantly higher for usefulness than Educational videos.
The majority (62.8%) were educational. More than half (59.1%) of videos were deemed useful, but only 6.5% were very useful. The study found no significant correlation between usefulness and metrics like duration, views, or likes, though the number of posted days was significantly higher in the useful group compared to the slightly useful group. Limitations include the dynamic nature of YouTube search results and ranking criteria. The implications suggest YouTube is a promising but inconsistent information source, with a need for more comprehensive video content on alternative medications and treatments.
