The Verdict

Data Conditioning

• Data extracted from www.cricinfo.com• Only ODI data considered• A player’s all round performance per

match is calculated as

Perf = Runs Scored + (Wickets taken X 20) + (Fielding dismissals X 10)

• Each wicket taken is equivalent to 20 runs• Each fielding dismissal is equivalent to 10 runs

HA = India wins when Sachin performs better than his average
