A/B Testing and Practical Experiment Analysis

In this lesson, we will learn A/B testing and practical experiment analysis. We will understand control and treatment groups, conversion rate, random assignment, sample size, statistical significance, p-value, confidence interval, and correct interpretation of experiment results through practical examples. ## Lesson objective In this lesson, we will learn A/B testing and practical experiment analysis. In the previous lesson, we covered correlation and simple linear regression. We learned relationship between two numerical variables, Pearson correlation coefficient, difference from causation, regression line, slope, intercept, residual, and R-squared.
