Descriptive analytics focuses on summarizing and interpreting historical data to understand patterns and trends. Analyzing past admissions and length of stay (LOS) data fits perfectly within this definition, as it involves reviewing previous data to draw insights about what has occurred in the past. This type of analysis helps organizations understand their performance and make informed decisions based on historical context. Other options reflect different types of analytics. For instance, calculating future revenue involves predictive analytics, which uses historical data to forecast future trends. Creating business models for new services pertains to prescriptive analytics, which provides recommendations based on data analysis. Determining staffing needs for the next month may involve forecasting and planning, again moving beyond the scope of mere descriptive analysis. By focusing on historical data and its implications, analyzing past admissions and LOS data is an exemplary showcase of descriptive analytics.
