Statistics for Data Science

Statistics for Data Science is the application of statistical principles and methods to the practical challenges of extracting insights and building models from large, complex datasets. It provides the fundamental framework for a data scientist's workflow, from using descriptive statistics for initial data exploration and probability for understanding uncertainty, to employing inferential techniques like hypothesis testing (crucial for A/B testing) and regression for making predictions. Ultimately, these statistical tools are essential for validating machine learning models, quantifying confidence in results, and ensuring that data-driven conclusions are sound, reliable, and actionable.
