What You Will Learn

  1. Practical Statistics

    35 hours to complete

    A solid foundation in statistics is essential to making sense of data in any field, but most courses focus on theory, rather than modern use cases. This course is designed to cut through the noise and teach you the concepts and techniques you need to know to tackle common real-world challenges, such as analyzing AB tests and building regression models.

    Prerequisite knowledge

    1. Simpson’s Paradox

      Examine a case study to learn about Simpson’s Paradox.

      • Binomial Distribution

        Learn about binomial distribution where each observation represents one of two outcomes and derive the probability of a binomial distribution.

        • Bayes Rule

          Build on conditional probability principles to understand the Bayes rule and derive the Bayes theorem.

          • Sampling Distributions and Central Limit Theorem

            Use normal distributions to compute probabilities and the Z-table to look up the proportions of observations above, below or in between values.

            • Hypothesis Testing

              Use critical values to make decisions on whether or not a treatment has changed the value of a population parameter.

              • T-Tests and A/B Tests

                Test the effect of a treatment or compare the difference in means for two groups when we have small sample sizes.

                • Logistic Regression

                  Use logistic regression results to make a prediction about the relationship between categorical dependent variables and predictors.

                  • Course Project: Analyze A/B Test Results

                    In this project, you will be provided a dataset reflecting data collected from an experiment. You’ll use statistical techniques to answer questions about the data and report your conclusions and recommendations in a report.
