A psychologist investigated the impact of a 45-minute aversion therapy session on smartphone addiction. Using a repeated measures design, 17 participants were assessed on a standardized smartphone addiction scale (where higher scores indicate greater addiction) before and after the session.
Each participant obtained a unique total score in the 'before' condition, with a maximum possible score of 50 and a median score of 28.
How many of the participants had a score less than the median in the 'before' condition? Explain your answer.
