Correlation analysis identifies relationships between variables, helping businesses understand dependencies and influences. Power BI development use DAX or integrate Python and R scripts for detailed correlation matrices. Visualizations like heatmaps and scatter plots make these relationships easier to interpret. For instance, a correlation analysis might reveal how marketing spend influences sales or how customer satisfaction impacts retention rates. Incorporating this analysis into Power BI dashboards enables businesses to focus on key drivers of success, optimize strategies, and prioritize initiatives that yield the highest impact.
