Free Udemy Course 2025: Data Science: Probability and Statistics

Are you ready to move beyond just spreadsheets and start making data-driven decisions based on solid statistical evidence? If you know that a career in Data Science, Business Intelligence, or Analytics demands more than simple averages, this course is your complete guide to building that essential quantitative foundation.Master the Statistical Foundations of Data Science and Business AnalysisThis is the practical, hands-on course you’ve been looking for. We designed it for one purpose: to give you the practical skills to confidently handle data and make reliable statistical inferences.By the end of this course, you will be able to:Build a solid foundation in descriptive statistics (mean, median, dispersion).Master core probability concepts like conditional probability and Bayes' Theorem.Understand and apply key probability distributions (Binomial, Poisson, Normal).Perform real-world hypothesis testing (like T-tests) to validate business decisions with data.Why is Statistical Fluency Your Career Superpower?In the modern world, data is the new oil. But raw data is useless. The real value is in the insights extracted from it. Companies like Google, Netflix, and Amazon use statistical models as the backbone of their decision-making. If you want a career in data, you must speak the language of statistics.This course is your translator. It bridges the gap between being a "Data User" (who just looks at dashboards) and a "Data Analyst" (who can build and question them). We ensure you have the conceptual clarity and the Python coding skills to work with data confidently and responsibly.How This Course is Taught (Your Practical Toolkit)We believe the only way to learn statistics is by doing. We'll start from Lesson 1, "Introduction to Data and Variables," and build your knowledge logically, module by module.Clear & Simple: We have broken down complex topics like Bayes' Theorem, the Central Limit Theorem, and p-values into easy-to-follow steps.Real-World Focus: We emphasize practical application over abstract theory. We use real-world examples to discuss common pitfalls like sampling bias, effect sizes, and the limitations of statistical tests, ensuring you become an effective and ethical data analyst.You will gain the skills to handle data quality issues, outliers, and missing values. You'll learn to construct and interpret confidence intervals and execute one-sample and two-sample T-tests to test real hypotheses.Ready to start your data science journey with a rock-solid statistical foundation?Enroll now, watch the free preview lectures, and begin building the quantitative skills that employers demand!
