Biostats Made Simple Series
The Biostats Made Simple series is led by Dr. Christine Ramdin. Each lecture covers fundamental biostatistics concepts that every resident and/or early career researcher should know. The series provides learners with the fundamental knowledge regarding: descriptive and inferential statistics, chi-square tests, p-values, confidence intervals, regression analyses, power and sample size, interrater reliability, and more.

Research Learning Series (RLS) - Biostats Made Simple: Session 9
Apr 11, 2025
In this session, we conduct a review of the previous 8 sessions and provide examples of databases available in SPSS format for analysis. We also introduce the National Hospital Ambulatory Care Survey (NHAMCS) database, how to conduct basic analyses using this database, and how to query the database to conduct more complex analyses.
