Statistical Analysis
Statistical Analysis is a key process in clinical trials that helps make sense of research data to determine if medical treatments are safe and effective. It's like being a detective with numbers - taking all the information collected during a clinical trial and using mathematical tools to understand what the results really mean. This includes checking if a new drug works better than existing treatments, determining the right dosage, and ensuring patient safety. While there are various software tools used for this (like SAS, R, or SPSS), the core concept remains the same: using numbers and data to make informed decisions about medical treatments.

Example Interview Questions
Senior Level Questions
Q: How would you handle missing data in a clinical trial?
Expected Answer: A senior statistician should discuss various approaches like multiple imputation, sensitivity analyses, and explain how they would document and justify their chosen method to regulatory authorities.
Q: What considerations go into designing a Phase III clinical trial?
Expected Answer: Should discuss sample size calculations, randomization methods, controlling for bias, defining primary and secondary endpoints, and planning interim analyses while maintaining study integrity.
Mid Level Questions
Q: What statistical methods would you use to analyze safety data in a clinical trial?
Expected Answer: Should explain common approaches like adverse event frequency analysis, time-to-event analysis, and how to present safety data in reports that non-statisticians can understand.
Q: How do you determine sample size for a clinical trial?
Expected Answer: Should discuss power calculations, effect size estimation, and how practical considerations like dropout rates influence sample size decisions.
Junior Level Questions
Q: What is a p-value and why is it important in clinical trials?
Expected Answer: Should be able to explain in simple terms what p-values mean and their role in determining whether study results are statistically significant.
Q: What's the difference between a primary and secondary endpoint?
Expected Answer: Should explain that primary endpoints are the main outcomes being studied, while secondary endpoints provide additional supportive information.
