Resumen

The present paper is a practical guide on exploratory data analysis (EDA) for researchers with limited background in statistics. EDA helps examine data relationships, patterns, and anomalies to, ultimately, determine the next steps and direction of the research. By providing hands-on examples and sample code in R, the paper equips readers with the knowledge and skills to draw insights from basic yet essential data summaries and visualizations.
