Data science encompasses a wide range of tasks and applications across various industries. Below are some key tasks and real-world examples that illustrate how data science is applied to solve problems and drive innovation.

Predictive Analytics

Predictive analytics involves using historical data to forecast future outcomes. For example, in healthcare, predictive models can forecast disease outbreaks like dengue or COVID-19 by analyzing historical disease data, weather conditions, and population demographics. Techniques such as time series analysis (e.g., ARIMA) and machine learning models (e.g., Random Forest) are commonly used.

Customer Segmentation

Customer segmentation helps businesses group customers based on behavior or demographics to personalize marketing strategies. In retail, clustering algorithms like K-means are used to analyze purchase history and demographic data, enabling targeted marketing and personalized recommendations.
