Highlights: Multiple Correspondence Analysis for student satisfaction data (Jupyter Notebook)
This report presents an analysis of student feedback data regarding study support, academic accessibility, and staff responsiveness. The analyst employed two statistical approaches: descriptive analysis examining frequency distributions and inferential analysis using Multiple Correspondence Analysis (MCA).
Key findings reveal that Net Promoter Scores (NPS) were consistently high across all student groups, though senior students showed significantly lower survey participation. Many students hadn’t used tutoring services, resulting in incomplete tutor-related responses. The MCA identified two main variation components: tutor usage and staff responsiveness (first component), and NPS with class standing (second component).
Notable patterns emerged showing freshmen ranked NPS lower than sophomores and juniors, suggesting satisfaction increases with experience. Tutor-related metrics dominated the data variation, masking other parameters’ relationships. The analysis revealed potential correlations between academic success, academic support, and clear communication, though statistical significance wasn’t formally tested.
The report recommends engaging senior students for their valuable long-term perspective, tracking students longitudinally to observe changing perceptions, and considering a simplified NPS scale given the skewed distribution toward high scores. The analyst suggests dedicated statistical tests are needed to properly assess correlations between non-tutor metrics, as current relationships remain masked by tutor-usage data.

Highlights: Trends in Breeding and Biotechnology Research: A Review. (Presentation)
This report reviews quantitative aspects of scientific research on trees, plants, and rangeland species in Iran, analyzing what has been studied and how. Comparing government-funded projects with university dissertations revealed clear differences in priorities: students favor quicker lab-based topics like genetic analysis, while institutions cover broader practical areas. Notable gaps were identified, with ecologically and commercially significant species like oak and Damask Rose receiving uneven attention across research domains. A panel of experts recommended prioritizing endangered, valuable, and ecosystem-critical species, proposing actions ranging from conservation to stress-response studies. The report concludes by calling for better organization of existing findings and a clearer roadmap for future research investment. This report was prepared in Persian (with an English translation available in the slideshow notes) and presented at the Research Institute of Forests and Rangelands in Iran in 2009.

Miscellaneous Projects:
Land Use Change in Tennessee - Nashville Software School
Tools: Python (SciKit), R (ShinyApp)
Key Features: Principal Component Analysis, k-Nearest Neighbors
-
The objective of this project was to elucidate patterns and hypothetical rationales for land use changes in Tennessee. It comprised two sub-projects:
-
A slideshow reviewing the methodology and results is included with the phase II set of files.
-
The visualizations depicted various correlations between land availability and valuation across counties. Analyses suggested the predominant criteria influencing land value are proximity to major metropolitan areas and agricultural profitability.
-
In summary, this project leveraged statistical programming languages and multivariate analysis to glean scientific insights into drivers of land use trends. The interactive dashboards and dimension reduction models provide data-driven understanding of how exurban dynamics shape land use patterns over time. Further research could relate the identified factors to policies on zoning, land conservation, transportation infrastructure, and urban development.
Improve College-Going and College-Readiness - Division of Research and Evaluation, TN Dept of Education
Tools: Python
Key Features: Principal Component Analysis
-
This repository comprises the data and computer code (in Python, in a Jupyter notebook) for an assessment project to identify measures that can evaluate high school graduates’ preparedness for collegiate studies.
-
Researchers have a great interest in enhancing college readiness for all youth and increasing the rate of postsecondary enrollment among graduates. The community is equally passionate about improving its students’ postsecondary success. For many of these students, college is not perceived as a viable option. Researchers posit that the district can improve college readiness among all district students by first identifying high schools to serve as “models of excellence” and then learning from these exemplars about best practices for producing “college-ready” students who enroll and persist in postsecondary education. Therefore, the available data was examined to recommend a model school.
-
Utilizing principal component analysis (aka dimension reduction), viable criteria were selected, upon which model schools were chosen. It appears that the most distinguishing factors to utilize for scoring are:
- The standardized grades (mathematics, SAT assessments)
- Enrolling for college. The two metrics that seem most relevant are: Enrolling for a 4-year degree (i.e., a strong education), and enrolling shortly after high school (an index of passion for education).
-
However, regarding data quality, there were both missing values and duplicated entries in the dataset. The strategy to manage the data was deliberated and implemented. Further research avenues (disaggregating the data within sub-regions) were suggested.
Logistic Regression - Nashville Software School
Tools: Python
- This Jupyter notebook was developed to exhibit the concept of logistic regression and how to implement this technique in Python. The code generates a logistic regression model, prints the model summary, exports and prints the coefficients, calculates predicted probabilities, and visualizes the logistic regression model along with the original data. The logistic regression model is applied to a binary response variable based on an explanatory variable. The visualization helps to understand how well the logistic regression model fits the data.
