When a batter receives a base on balls, the result is not counted as an at bat. A statistic called on base percentage (OBP) treats a base-on-balls as the same as a hit. The formula for finding OBP is:

OBP = (Hits + Bases on balls) / (At bats + Bases on balls)

Find the OBP for each batter on your team. Which batter has the highest OBP? Which has the lowest?
