Answer: B.) Bar
Explanation: When trying to compare batting average of all players on the leagues baseball team, the batting average of the players in each team is measured and the data grouped by team. When measuring changes, differences or comparison, the bar chart and line chart seems to be the best for such purposes. However, depending on whether the changes in measured data is large or small, the bar chart seems best suited in cases where large differences exists, while line graphs are better when small differences exist between measure data.
