Give an example of a statistical data analysis project you have worked on.

Sample answer to the question

During my previous role as an Analytical Chemist, I worked on a statistical data analysis project for a pharmaceutical company. The project involved analyzing the potency of different drug formulations and determining the relationship between various factors such as temperature, humidity, and storage duration. I collected data from multiple batches of the drug and used statistical software to perform regression analysis and calculate correlation coefficients. The results highlighted the impact of environmental conditions on drug potency and provided insights for optimizing storage conditions to ensure product stability. This project helped the company make informed decisions regarding storage and distribution practices, ultimately improving product quality.

A more solid answer

During my role as an Analytical Chemist at XYZ Pharmaceuticals, I led a statistical data analysis project focused on the evaluation of drug stability. The project aimed to determine the shelf-life of a new drug formulation by analyzing the degradation kinetics under various storage conditions. I designed an experimental setup to mimic real-world scenarios and performed accelerated stability studies. Using statistical software, I applied regression analysis and calculated Arrhenius activation energies to predict the drug's stability at different temperatures. The results allowed the company to establish appropriate storage conditions and expiry dates for the product. I effectively communicated the findings through detailed reports and presentations, providing crucial information for regulatory compliance and product quality assurance.
