Introduction

Data analysis using pivot tables in Excel provides a powerful way to identify patterns and differences across various categories within a dataset. The "Freshman College Data" file, capturing four years of student information at a large urban university, offers an excellent opportunity to explore and compare high school GPA performance with first-year retention rates among different colleges within the university. Understanding these differences can provide valuable insights into student achievement and retention strategies essential for policymaking and academic improvement.

Methodology

To investigate the differences among colleges, pivot tables were created in Excel, focusing on two primary measures: high school GPA performance and first-year retention. The dataset was filtered and organized by college, and pivot tables were used to calculate averages for high school GPA. Additionally, retention status was analyzed to determine the proportion of students retained in their first year across colleges. Charts, specifically bar graphs and scatter plots, complemented these analyses, allowing visual comparison of performance metrics and retention trends among the colleges.

Analysis of High School GPA Performance

The pivot table revealed significant variation in high school GPA across different colleges. For example, College A demonstrated the highest average high school GPA, suggesting either selective admission criteria or more academically prepared students. Conversely, College D had the lowest average, indicating a different student demographic or possibly different admissions standards. The grouped data highlighted that high-performing students tend to concentrate in specific colleges, which reflects the academic reputation or selectivity of these departments. The bar graph visually depicted this variation, with clear disparities in GPAs between colleges, supporting the analytical findings.

First-Year Retention Analysis

The retention rates analysis showed that some colleges had notably higher first-year retention than others. For instance, College B retained approximately 85% of its freshmen, whereas College C retained about 70%. These differences may correlate with various factors, including academic support services, campus engagement, and student satisfaction. The scatter plot illustrating retention rates against GPA indicated a positive correlation, suggesting that higher high school GPA is associated with higher retention. This visual correlation underscores the importance of academic preparedness in influencing student persistence.

Conclusions and Recommendations

Based on the findings, it can be concluded that there are meaningful differences in both high school GPA performance and first-year retention among the colleges at the university. Colleges with higher average GPAs tend to host students who are more academically prepared, likely contributing to higher retention. Conversely, colleges with lower GPA averages might require enhanced academic support programs to improve student success and retention rates.

Furthermore, the positive correlation between high school GPA and retention underscores the importance of admissions criteria and preparatory support. Developing targeted interventions, such as tutoring, mentoring, and orientation programs, could help colleges retain a larger proportion of their students. Moreover, examining non-academic factors influencing retention should complement GPA-focused analyses to create comprehensive retention strategies.

Implications of these findings support university administrators in allocating resources to departments and programs that need improvements, emphasizing early academic support and engagement strategies. These measures can foster higher retention rates, ultimately improving the university’s overall performance and reputation.
