Association Rules for High University Rankings

Association rules find patterns by linking different factors. Here, they identify combinations of factors (like high teaching quality and a high number of students) that are often found in top-ranked universities. Each rule includes:

Antecedent: Conditions that need to be true, such as "Teaching Score ≥ 70" or "High International Student Percentage."

Consequent: The outcome, is typically a high university rank.

Metrics in Association Rules

1. Support: Indicates how often a rule applies in the data. For example, if support is 0.3, the rule applies to 30% of universities.

2. Confidence: Shows how often the outcome is true when the conditions are met. A confidence of 0.85 means the outcome happens 85% of the time when the conditions are true.

Key Insights from Association Rules Analysis

1. Teaching Quality Boosts Ranking: Universities with strong teaching scores are often top-ranked, showing that teaching quality is crucial for university success.

2. International Appeal Matters: High percentages of international students are often found in top universities, indicating the importance of international outlook and diversity.

3. High Scores Across Factors Contribute to Top Ranks: The top-ranked universities usually excel in multiple areas, including teaching, research, and international diversity, rather than just one factor.
