2. Calculate Brady's yards per attempt (YPA): YPA=Total Passing Yards / Total Passing Attempts YPA=79,204/10,598 YPA = 7.47 3. Calculate Brady's touchdown percentage (TD%): TD% = (Total Touchdown Passes / Total Passing Attempts)*100 TD% (581/10,598) * 100 TD% = 5.48% Calculate Brady's interception percentage (INT%): INT%=(Total Interceptions/Total Passing Attempts) * 100 (191/10,598) * 100 INT% INT% = 1.80% Now, use these values to calculate Brady's passer rating using the NFL's formula: Passer Rating = ((CMP % -30)/20) + ((YPA-3)/4)+(TD% *20) - (INT%*25) Passer Rating = ((63.88-30)/20) + ((7.47 - 3)/4)+(5.48*20) - (1.80*25) Passer Rating = (33.88/20) + (4.47/4)+ 109.6-45 Passer Rating = 1.694 +1.117+109.6-45 Passer Rating = 112.411
