Hypothesis Testing in R: Practical Statistical Analysis

Making sense of data requires knowing whether observed patterns are genuine or merely the result of random chance. This text-based course guides you step by step through the principles and applications of hypothesis testing using R, transforming abstract statistics into clear, actionable analytical workflows. You will build a solid foundation in core statistical concepts before writing analysis code in R. You will work through realistic data scenarios, evaluating evidence, comparing groups, and interpreting statistical results with precision. What you'll learn: - Understand fundamental concepts including null and alternative hypotheses, p-values, significance levels, and degrees of freedom - Explore probability distributions and determine when to apply specific parametric and non-parametric tests - Perform single-sample and two-sample t-tests to evaluate differences between continuous datasets - Apply one-way and two-way Chi-Square tests to examine relationships among categorical variables - Utilize modern R packages and tidy data principles to streamline statistical testing workflows - Interpret statistical outputs correctly and calculate effect sizes to evaluate real-world significance The course starts with essential statistical definitions and terminology before progressing to practical R implementations and structured data analysis exercises. Designed specifically for beginners, this course requires no advanced mathematical background or prior experience with hypothesis testing.
