Data Analysis with Correlation and Linear Regression

Understanding how different variables interact is the cornerstone of data-driven decision-making. This text-based course guides you from the fundamental principles of statistical association to building and interpreting your own predictive models. You will learn to identify patterns, evaluate the strength of relationships, and make informed predictions based on data. What you'll learn: - Understand the core concepts of correlation, covariance, and statistical significance. - Calculate and interpret Pearson and Spearman correlation coefficients. - Build and evaluate simple and multiple linear regression models. - Apply modern diagnostic techniques to check model assumptions and avoid overfitting. - Interpret regression coefficients and statistical outputs to make real-world predictions. This course begins with essential terminology and foundational statistical concepts before moving into practical modeling techniques and interpretation. It is designed for beginners who want to build a strong foundation in data analysis, with no prior advanced mathematics or programming experience required.
