This document provides an overview of common data science tasks, algorithms, and examples. It describes tasks like classification, regression, clustering, anomaly detection, time series analysis, and association analysis. For each task, it lists example algorithms like decision trees, k-means clustering, and Apriori association rules. It also provides real-world examples of applying each task, such as predicting political affiliations through classification or identifying customer segments through clustering. Finally, it outlines the topics that will be covered in a data science course, including algorithms, applications, and the data science process.
