Explanation:

Quantitative variables are numerical and represent measurable quantities. Qualitative variables are categorical and represent non-numerical attributes or groups.

• League: Represents a categorical group (American League/National League), so it is qualitative.
• Wins: Counts the number of games won, a numerical measurable value, so it is quantitative.
• Team Salary: A numerical monetary value, measurable, so it is quantitative.
• Attendance: Counts the number of people, a numerical measurable value, so it is quantitative.
• HR (Home Runs): Counts the number of home runs, a numerical measurable value, so it is quantitative.
• BA (Batting Average): A numerical rate/statistic, measurable, so it is quantitative.
• ERA (Earned Run Average): A numerical rate/statistic, measurable, so it is quantitative.
• Year: A numerical label for a specific season, but in this context, it is a fixed categorical identifier for the 2021 season, so it is qualitative.
• Net Worth: A numerical monetary value, measurable, so it is quantitative.
