Carolina Ragolta

MBA Student at Stanford Graduate School of Business

I majored in engineering and minored in economics as an undergraduate, but the content of Business Analytics and Economics for Managers showed me new ways for using the theoretical foundations I already had.

I was able to use Business Analytics when a project on truck optimization for my site came up while I was enrolled in the course. I was able to apply the statistical concepts that I learned during the course to create an optimizer tool for truck usage and scheduling at the mine. This tool resulted in significant cost savings, which was highly valued by the site management team.

Professor Hammond is an outstanding and inspirational teacher. Her Business Analytics course helped to demystify statistics for me, rendering the subject matter approachable and appealing. The fabulous visualizations and graphics, combined with relevant and interesting case studies, brought the concepts to life in a stimulating and engaging way. Mastery of data analysis is critical for business success and I now feel confident that I have the foundations in place. I am looking forward to embracing this capability further in my career.

I am applying concepts from the Business Analytics course in my current venture. From designing surveys to hypothesis testing, every aspect of data collection and analysis informs our customer validation process.

The way Business Analytics blended numbers with the impact on business forecasting and improvement of business processes was simply amazing. The real-life cases from different spheres made the learning more insightful. The subject further helped affirm the power of data/numbers in analyzing and forecasting about a particular business initiative.

I'm using regression analysis and other statistical concepts from Business Analytics to build predictive models, analyze trends, and conduct surveys and hypothesis testing. Business Analytics has helped me pursue a career in data analytics and land a job as a Business Intelligence Analyst at Ministry of Justice New Zealand. I'm leading a few modelling and reporting projects across the Ministry using the knowledge I gained from the course.

The excel I learned from Business Analytics has become useful as I started working as a data analyst for an economic research firm, BMI Research. The techniques I learned make it easier to comprehend the more complex functions. In addition, the integrated learning I took from the case studies allows me to apply “total analysis” in my everyday work and assessments, which is in fact the core business of my company.

Thanks to Business Analytics, I learned to apply statistical analysis to real world problems. For instance, I am currently doing a research project using regression analysis to see if we can predict emergency department demand on any given day - important for staffing and resource allocation.

[With Business Analytics], I discovered a new-found love of data analytics. I was fascinated to learn about ways we can use data to systematically seek an answer to a specific business question or predict the outcome of a scenario given past behavior. This new interest has motivated me to pursue a career in data science (a field that combines statistics, analytics, and business knowledge), which I have begun to work toward since I finished [the course].
