Can you post the data gathering section of your dissertation once it's been marked?
"In the process of collating data I shared a link to the online questionnaire on the Scottish football website 'Pie and Bovril'. This location was chosen with no regard to its demographics, and with no prior personal experience or familiarity with the forum or its users, despite it being the largest online forum dedicated to the subject of this dissertation. The questionnaire was shared on a number of occasions, with a specific request made to seek out supporters of a specific club due to a perceived lack of response."
Full marks. Absolutely legitimate, worthwhile insightful results. All appropriate data gathering methods followed flawlessly.
