In fact, the evidence claims at a 5% significance level that mixed race, dark and very dark players are receiving around a half fewer bookings compared to very light players, and light players are getting booked at a rate of 50% more often, on average and ceteris paribus, with the trend continuing on through our poisson model. Our regression coefficients also show a correlation to where you are more likely to receive a booking if you are a lighter player, with numbers decreasing across the range of skin tones, for both the linear and poisson data.  Although there could be a case made that using the significant evidence found (other factors still have to be taken into account), referees are carrying themselves in a more lenient manner with players outside their skin tone (as all referees in this database would be classified as very light), we can conclude with our original hypothesis being false. There is no evidence on the basis of both the linear and poisson model, that darker skinned players are a victim of racial bias and therefore are not more likely to receive disciplinary sanctions compared to their lighter-skinned counterparts.
