We explore key areas of data science, including question formulation, data collection and cleaning, visualization, statistical inference, predictive modeling, and decision-making. These include languages for transforming, querying, and analyzing data; algorithms for machine learning methods, including regression, classification, and clustering; statistical concepts of measurement error and prediction; and salable data processing techniques.
