I learned Power BI by working with a dataset of patients' emergency room visits, which provided a hands-on and practical way to understand the software's capabilities. By importing and cleaning the data, I explored various visualization tools to analyze patient demographics, visit timings, and reasons for visits. I created interactive dashboards to identify trends and patterns, such as peak visit hours and common medical issues, which enhanced my ability to interpret complex datasets visually. This approach not only improved my proficiency in Power BI but also deepened my insights into healthcare analytics.
