With the results shown above, we can deduce various findings. When looking at the number of cards given out by referees as the seasons go, there is evidence of leniency within the Premier League. On average, the total amount of cards received by players has decreased by around 0.19 cards, with the largest decrease coming in the 2015/16 season at 0.3 cards per game, which was also found to be significant at the 1% level. However, leniency in cards received does not correlate with leniency in fouls given as evidenced with an increase in fouls, although relatively small, at roughly 0.1, with the commission of an extra foul increasing the card count on average (and ceteris paribus) by the same value. This was anticipated prior to the regression and unsurprisingly, this variable accounted for over 50% of the variation in total cards received also. Being a ‘veteran’ player was deemed to decrease the total amount of cards, although only minimally at the 5% level, suggesting experience does outweigh a natural decline in overall athleticism, but only marginally.
