I think this question is a matter of personal interpretation, however... For a pitcher, typically the ERA, or Earned Run Average, is the given the first look. The ERA corresponds to the number of earned runs given up based upon a complete nine inning game. Every run that scores though is not necessarily considered "earned". For example, if a batter reaches base on a fielding error, that base runner, if he scores, is not counted against the pitcher as an earned run. For a batter, typically the BA, or batting average, is given the most weight. Batting average is simply calculated by taking the number of hits divided by the number of at bats. Again, like the ERA, not every "appearance" is considered an at bat. As an example, if a batter walks, it is not counted as an at bat for that hitter.
