The sample size of the research was limited to students aged 17-19 from one college, which is not wholly representative of the target audience aged 14-19. To be fully valid, feedback would need to be gathered from a more diverse audience from different countries and ages. While bias is possible due to personal relationships with some feedback sources, the extremely negative YouTube comments received suggest they were not influenced by personal affection. For the feedback to be considered reliable, a repeated feedback process would need to produce consistent results over time from different participants.
