Card happy referees

Continuing the series on referees (parts I, II and III) I’m going to move on and look at which referees dish out the most cards per game. Once more I’m only going to include the 23 referees with a sizable amount of experience (76+ games).

In each of the table the number will be in the format ‘t (y+r)’. T represents the total number of cards shown, y is the number of bookings and r is the number of dismissals. Once more I’ll look firstly at the total cards per game. (The average here is 3.24 with a standard deviation of 0.48)

Referee Total cards per game Referee Total cards per game
M Riley 3.97 (3.74+0.22) M Halsey 2.27 (2.14+0.13)
M Dean 3.80 (3.59+0.21) P Durkin 2.31 (2.20+0.10)
P Dowd 3.61 (3.37+0.24) J Winter 2.40 (2.33+0.07)
S Bennett 3.61 (3.40+0.21) D Gallagher 2.72 (2.53+0.20)
G Barber 3.60 (3.40+0.20) U Rennie 2.73 (2.65+0.09)

How about giving cards to the home team? (Average 1.39, standard deviation 0.25)

Referee Home cards per game Referee Home cards per game
M Dean 1.78 (1.68+0.09) J Winter 0.83 (0.81+0.02)
M Riley 1.76 (1.63+0.13) M Halsey 0.89 (0.84+0.05)
M Clattenburg 1.60 (1.51+0.09) P Durkin 0.97 (0.93+0.03)
R Styles 1.57 (1.47+0.10) N Barry 1.12 (1.06+0.05)
L Mason 1.53 (1.49+0.05) D Gallagher 1.16 (1.08+0.08)

And then showing cards to the away team (average 1.75, standard deviation 0.23)

Referee Away cards per game Referee Away cards per game
M Riley 2.20 (2.11+0.10) P Durkin 1.34 (1.27+0.07)
P Dowd 2.17(2.00+0.16) M Halsey 1.38 (1.30+0.08)
S Bennett 2.14 (1.98+0.15) U Rennie 1.41 (1.34+0.07)
G Barber 2.08 (1.96+0.11) J Winter 1.57 (1.52+0.05)
L Mason 2.03 (1.88+0.15) D Gallagher 1.57 (1.45+0.12)

Now we start to get some interesting results. For example Mike Dean gives the most cards to home teams and is ranked sixth when it comes to giving cards to away teams and Uriah Rennie is a similar story. Conversly Phil Dowd gives the 10th most cards to the home team and yet ranks second in the number of cards he shows to away teams. Over the next couple of posts I’ll look at whether this could be the result of a bias or can be explained another way.
