A university arranges scientific communication workshops for its researchers. The attendees of the workshop are able to publish their work within a year 91.0% of the time. New researchers who are unable to attend the workshop are only able to publish within a year 58.0% of the time. 59.0% of new researchers choose to take part in the workshop.
