RQ 1: What are the economic and social factors that affect global university rankings?
The features that are clearly important relative to the other features are the Gross Domestic Product (GDP) , the Rule of Law and the Government Effectiveness of the country. These have a large impact on the country’s university rankings. These three features are all related to the government and how they handle the country. By looking at these factors, an assumption can already be made about the country’s ranking. It proves that the way a country is managed plays an important role in its educational system. One can argue that it makes sense that these economic and social factors have the most influence. Notable features like Scientific and Technical Journal Articles, Adolescent Fertility Rate and Labor Force Participation Rate can also slightly influence the rankings. However, features such as Access to Electricity, GDP growth, Foreign Direct Investment and etc. remain minimal to insignificant to the rankings. From this, features that are not within the 95% cumulative importance can be removed. Overall, the features regarding the performance of the government prove to be the most important factors that influence a country’s university rankings.
RQ 2: Do countries with similar indicator values also have similar rankings? (Focused on PH)
The hierarchical clustering dendrogram shows that the countries are grouped into three clusters. The Philippines is part of the green clusters along with countries like Morocco, Romania and Costa Rica. This indicates that the Philippines have the most similar features to these countries compared to others in other clusters like the United States and Singapore.
The three main clusters namely Cluster 1 (yellow), Cluster 2 (green), and Cluster 3 (red) are the main clusters. The top indicators of each cluster was calculated by getting the deviation from the average of all of the clusters. For Cluster 1, the feature Merchandise Trade stands out as the main differential indicator. These are countries like Poland, Belarus, Portugal and Singapore. For Cluster 2, features like Adolescent Fertility Rate, GNI Per Capita and Merchandise Trade are the top indicators. These contain countries like the Philippines, Costa Rica, Peru and others. For Cluster 3, the GNI Per Capita and Merchandise Trade are the top indicators. These are countries like the United States, France and Italy. It is clear that the Merchandise Trade and GNI Per Capita are the main differences between each cluster. This gives us insights on how the countries of each cluster are similar in these factors and mainly grouped by this. Economic indicators stand out as the main differences between the clusters.
Using the Kruskal-Wallis test, it was found out that the distributions of the country university rank differ significantly between at least two clusters. The similarity of tank within clusters was then calculated using Coefficient of Variance. Cluster 1 contains the middle valued rankings with a CV of 50.54% indicating a high relative variability. The rankings are diverse with some outliers with higher-than-average values. Cluster 2 contains the lowest rankings among the three clusters. They have the highest relative variability but a spread-out distribution. This can indicate the disconnectedness between indicators and the rankings in Cluster 2. Lastly, Cluster 3 contains the highest rankings and lowest relative variability. This suggests a strong high-performing group.
Overall, this can suggest that the higher ranking countries (Cluster 3) are the most consistent while the lowest-performing countries (Cluster 2) are the most dispersed. Countries with similar values in features like Merchandise Trade and GNI Per Capita have been the main clusters. With Cluster 1 containing many first-world countries, it can be seen they are consistently ranked highly. The other clusters containing third-world countries show a dispersed distribution of rankings. This suggests that high-performing countries are consistently ranked higher and have similar rankings with countries like them. On the other hand, the low-performing countries with similar indicator values have varied rankings despite their similarity in indicator value.
RQ 3: Can rankings be predicted?
The graphs show the difference with the 3 models used for the study. The results show that among the models Linear regression showed a poor R2 score of 0.62 while comparing it to MLP Regressor and Random Forest. This indicates that it explains only 62% of the predictions while also showing significantly higher error rates with an MSE,MAE, and RMSE compared to MLP Reressor and Random Forest which indicates that linear relationships alone are not accurate to capture the factors that influence university rankings. These numbers also show that university rankings follow mostly non-linear patterns that require more modeling approaches to capture data more precisely.
The high R2 scores achieved by both MLP Regressor and Random Forest shows strong implications that university rankings can be predicted using economic and social indicators.This aligns with the analysis from RQ1 that GDP,Rule of Law and the Government Effectiveness of the country have the most influential factors. Due to the high R2 results it suggests that the relationship between economic and social factors with educational performance follows predictable patterns. The better results from MLP Regressor and Random Forest over linear regression model shows the complex nature of factors influencing university rankings. This aligns with the analysis from RQ2 that similar indicator values have varied rankings despite their similarity in indicator value, particularly in lowest-performing clusters. The MLP and Random Forest model better understands and sees these relationships between variables.
Overall, the results give useful insights for understanding the Philippines’ declining rankings. High accuracy models suggest that improvements in the most influential factors may lead to predictable enhancements in university performance.
Conclusion
The study provided insights about the relationship between a country’s global university ranking and the country’s economic and social situation. Realizing that the Philippines has an underperforming education system, it is a wake-up call to promote quality and effective education. High-performing economy and stable society countries become a role model for obtaining educational success. Through more analysis, it was concluded that the global university rankings were primarily related to economic indicators like Gross Domestic Product (GDP) and government performance like the Rule of Law and the Government Effectiveness. This shows that how the country is managed plays a vital role in affecting its educational sector. Countries with similar indicators also have similar rankings like the United States. The high-performing countries are the most consistent in the global university rankings as opposed to low-performing countries that have more dispersed rankings. This gives insights that high-performing countries have similar rankings while low-performing countries have scattered rankings.
The study also used machine learning models (Linear Regression, MLP Regressor, Random Forest) to predict the rankings of a country given its social and economic indicators. The random forest model provided the most accurate results as it can handle the interactiveness of the data and its threshold effects. The rankings were able to be predicted with a R^2 score of 92%.
Overall, in order to address the education problem of the Philippines, the solution shouldn’t just be to improve the educational sector but to also improve the country’s socioeconomic status. The country should focus on creating policies and programs to strengthen our social and economic sectors. A strong management of the country can be the key to improving the Philippine’s position in the global stage. Learning from high-performing countries, the Philippines has the ability to catch up, by focusing on improving the socioeconomic factors of the country.
