Training Course on Statistical Data Management and Analysis using R

Course Overview

The Statistical Data Management and Analysis using R training provides a comprehensive introduction to leveraging the R programming language for effective data manipulation, exploration, and statistical modeling. Through a series of hands-on exercises and real-world examples, participants will learn essential techniques such as data importation, cleaning, visualization, and modeling. By the end of the course, attendees will have the skills and confidence to tackle diverse analytical challenges, create reproducible reports using R Markdown, and apply statistical methods to extract meaningful insights from complex datasets.
